Introduction 1.1 Service bulletins 1.3 Working with surface-mount Contact QSC Technical Services to make sure you have the most up-to-date service bulletins for PowerLight Series amplifiers. Service bulletins may be distributed in hard copy, via fax, and electronically (Adobe Acrobat PDF) via CD-ROMs, FTP from the QSC web site (www.qscaudio.com), and e-mail. These service bulletins had been issued at the time this manual was printed: PFC0001, “PFC MOSFET Replacement” (PowerLight 6.0PFC and PowerLight 9.0PFC only); PFC0002, “PFC Power Supply Replacement Guidelines” (PowerLight 6.0PFC and PowerLight 9.0PFC only); and PFC0003, “Amplifier Goes Into Protect When Turned On” (all three models). components PowerLight amplifiers, like many modern electronic products, use surface-mount technology (SMT) components where appropriate in order to make high-density circuitry that is reliable and economical to manufacture. SMT components in the PowerLight amps are used in the small- signal and control circuits, so they do not handle significant amounts of power; therefore, they are subject to very little stress and should seldom fail. Sometimes they do fail, or they require replacement for a performance upgrade or modification. Thus, it is important to know how to work with SMT components. 1.2 The well-equipped service bench Specialized tools and equipment exist for soldering, unsoldering, and removing SMT components quickly and efficiently, but they are often expensive. Most SMT repairs, though, can be handled reason- To properly service QSC amplifiers, a technician needs the right tools. The technician’s service bench should have the following ably well with common tools and equipment, such as tweezers, solder braid, and fine-tip soldering irons. equipment: Two-terminal components (resistors, capacitors, • Digital multimeter with RMS AC voltage and current • Digital clamp-on ammeter • Dual-trace oscilloscope • Audio distortion analyzer • Non-inductive load resistors, configurable as 8 ohms (min. 1800 watts capacity), as 4 ohms (min. 3200 watts capacity), and as 2 ohms (min. 4500 watts capacity) • Variable AC voltage source, such as a Variac or Powerstat variable transformer, with a rated current capacity of up to 50A (for 120V models) or 25A (for 230V models) • Low-distortion audio sine wave generator • Philips and flat screwdrivers • Soldering iron with a fine tip (25–60W recommended) • Rosin-core solder (60/40 or 63/37) • Long-nose pliers • Diagonal cutters • Wire strippers Automated test equipment, such as an Audio Precision worksta- tion, is very useful for servicing PowerLight amplifiers. Contact diodes, etc.) Removal 1. Use two soldering irons, prefer- ably about 25 to 40 watts, with fine tips. 2. With a soldering iron in each hand, hold one tip on the solder at one end of the component and the other tip on the other end (Figure 1.1). 3. Once the solder melts on both ends, grip the component between the two tips and lift it from the circuit board. 4. Use solder braid and a soldering iron to remove the solder from the two pads (Figure 1.2). Insertion QSC Technical Services to obtain applicable AP test files. 1. With a soldering iron and 60/40 or 63/37 eutectic-type solder, Servicing power supply modules will require some additional special-built equipment: • Power supply remote controller • PFC power supply fixture (for PFC modules only) • CMP box Becauseof the complexity of the PFC power supplies, QSC recommends they be serviced only by QSC. Figure 1.1. Solder braid Figure 1.2. melt just enough solder onto one pad to create a small mound (Figure 1.3). 2. Grasp the component in the middle with tweezers. Melt the small mound of solder with the iron and place the component across the two pads (in the correct orientation, if the compo- nent is sensitive to direction) and press it flat against the circuit board, with one end of the component immersed in the melted solder (Figure 1.4). 3. Hold the component in place and take the soldering iron away. Technical Service Manual 5 PowerLight 6.0 II, PowerLight 6.0PFC, and PowerLight 9.0PFC Let the solder harden to tack the component in place. 4. Fully solder the other end of the component to its pad. Let the solder harden (Figure 1.5). 5. Fully solder the tacked end of the component to its pad (Figure 1.6). Three-terminal components (transistors, etc.) Removal 1. With a soldering iron and solder braid, remove as much solder as possible from the middle terminal of the component. 2. With a soldering iron in each hand, hold one tip on the solder at the terminal at one end of the component and the other tip on the terminal at the other end. 3. When the solder on both ends melts, grip the component between the two tips and lift it from the circuit board. You might need to quickly touch the pad on the middle terminal with a soldering iron to melt any remaining solder that might be holding the component down. 4. Use solder braid and a soldering iron to remove the solder from the three pads. Insertion 1. With a soldering iron and 60/40 or 63/37 eutectic-type solder, melt just enough solder onto one pad to create a small mound of solder. 2. Grasp the component with tweezers. Melt the small mound of solder with the iron and place the component in the correct orientation across the three pads and press it flat against the circuit board, with one terminal of the component pressed into the melted solder. 3. Hold the component in place and take the soldering iron away. Let the solder harden to tack the component in place. 4. Fully solder the other terminals of the component to their pads. Let the solder harden. 5. Fully solder the tacked terminal of the component to its pad. Multi-pin components (ICs, etc.) Removal Removing a multi-pin SMT component is a delicate procedure. Ideally, you should use a soldering iron with an attachment that allows you to heat all the pins simultaneously. If such a soldering device is not available, use this procedure: 1. Use a soldering iron and solder braid to remove as much solder as possible from the pins of the component. 2. With fine tweezers, carefully try to lift each pin to see if it’s Solder free. If it’s not, touch it with the tip of the soldering iron and if necessary, use the solder braid to remove the remaining solder. 3. Repeat the process until all the pins are free and you can Figure 1.3. remove the component. Insertion 1. With a soldering iron and 60/40 or 63/37 eutectic-type solder, Tweezersmelt just enough solder onto one pad to create a small mound of solder. It is usually easiest to use a pad that corresponds to one of the end or corner pins of the component. Figure 1.4. 2. Grasp the component with tweezers.

Figure 1.6. 1.4 Series description QSC’s PowerLight Series amplifiers are high-performance professional audio products, designed primarily for live and touring sound and large-scale installations. This service manual covers the three most powerful models developed for the PowerLight Series: the PowerLight 6.0 II, the PowerLight 6.0PFC, and the PowerLight 9.0PFC. Each one has two audio channels and is three rack spaces tall. See page 2 for complete specifications. The PowerLight 6.0PFC and PowerLight 9.0PFC feature power supplies with power factor correction, which reduces peak current demand by drawing power throughout the AC voltage waveform. The PowerLight 6.0 II has power supplies that don’t have PFC but are simpler and less expensive to manufacture. The first four digits of the amplifier’s serial number indicate the month and year of manufacture in MMYY formay. For example, 0701xxxxx = July 2001). A serial number that starts with “13” indicates the amplifier was made during the model’s beta production. The PowerLight 9.0PFC entered production in May 1998. The PowerLight 6.0PFC followed in March 1999, and the PowerLight 6.0 II, in August 2002. Many PowerLight 6.0PFC amplifiers, however, have been converted by QSC Technical Services into PowerLight 6.0 II amplifiers, so you may encounter PowerLight 6.0 II amplifiers with serial number date codes that precede the model’s actual release date. The PowerLight 6.0PFC and PowerLight 9.0PFC ceased production in March 2004. 6 QSC Audio Products, Inc. TD-000083-00 1.5 Technical descriptions and theory of operation Power supplies QSC PowerLight amplifiers feature high-frequency switch-mode power supplies that help reduce noise, increase electrical efficiency, and lower weight. Two models, the PowerLight 9.0PFC and the PowerLight 6.0PFC, had power factor correction to reduce the peak current demand from the AC mains. They accom- plished this by drawing current throughout the AC voltage waveform, instead of just at the peaks, as most amplifiers and other electronic equipment do. The PowerLight 6.0 II was developed later, and its power supplies do not have power factor correction. All three models have a four- tier class H system of multiple rail voltages to boost efficiency. A power amplifier is most efficient at or near full power, yet the dynamic nature of music and other typical audio requires much less than full power most of the time. Thus, this class H scheme creates essentially four different “full-power” levels within the amplifier channel. The amplifier circuitry automatically and instanta- neously switches to the lowest rail voltage that will allow the reproduction of the audio signal without discontinuity. Each amplifier channel has its own power supply. In addition, each has a small “housekeep- ing” supply that manages the turn-on functions before the main power supply starts up. Audio circuitry The audio inputs are balanced to offer a high amount of common- mode noise rejection. The input balancing is done using an instrumentation amplifier arrangement, which uses a single op amp, arranged as a voltage follower or buffer, on each leg of the balanced input, driving a single op amp differential amplifier. The degree of common-mode rejection is dependent on the close matching of the impedance between each leg and ground and around the differential amplifier. The circuitry uses 1% precision resistors to ensure at least 40 dB of common-mode rejection. The differential amplifier circuitry includes a first-order high- frequency roll-off, down 3 dB at 280 kHz (nearly four octaves above the high end of the audio spectrum). This makes the amplifier less susceptible to RF interference, high-frequency oscillations, etc. The audio signal passes through a pre-clipper, which prevents the audio signal from driving the output section itself into actual clipping. This maintains damping on the channel output even during clipping so that it continues to tightly control the loudspeaker motion, which is something most amplifiers cannot do. A defeatable clip limiter on each channel reduces signal level when clipping occurs; it does not prevent clipping, but reduces the amount of distortion to inaudible or barely audible levels. An all-pass filter uses group delay to slow the audio signal by 4 μs, but the class H steps are controlled by the undelayed signal. This reduces IM distortion by ensuring that the steps are executed before the audio signal in the output section reaches the transition thresholds. The audio signal voltage is converted into current by transistors Q87 and Q89, to be precisely bifurcated into positive and negative halves by the current steering circuitry. These current signals are the controls for the output devices.The output devices are vertical MOSFETs, which are commonly used for very high power switching because of their power handling capability and general nonlinearity. Using them for linear audio amplifica- tion requires an unorthodox approach. In these three PowerLight amplifier models, each channel has eight MOSFET devices arranged in a full bridge configuration. Each one has a local management circuit called a current cell that controls and linearizes the device by providing the necessary compensation to make the MOSFET’s conductivity track the signal current. Technical Service Manual 7 PowerLight 6.0 II, PowerLight 6.0PFC, and PowerLight 9.0PFC Figure 1.7. Amplifiers without PFC draw current only at the peaks of the AC voltage waveform. Figure 1.8. An amplifier with PFC draws current throughout the AC voltage waveform. Figure 1.10. Most amps lose feedback during clipping, resulting in loss of damping and in “clip sticking.” Figure 1.9. The rail voltages of the output section switch among four tiers to reproduce the signal faithfully while maximizing efficiency. Figure 1.11. The pre-clipping scheme in the PowerLight 6.0PFC, 9.0PFC, and 6.0 II keeps the output signal clean despite the flat-topping of the waveform. 2. Servicing the amplifier 2.1 Mechanical disassembly and reassembly Introduction Replacing components will usually require removing the affected modules from the amplifier chassis. The two channels each have their own power supply module and audio module, and they share the line filter assembly and the input, output, and display board assemblies. Within the chassis, the power supply modules are on the bottom, and the audio modules are on top. Getting at a power supply module requires removal of its audio module first. The following instructions describe the procedure for removing both audio and both power supply modules. However, if you only need to work on one channel, you do not need to remove the modules from the other. Key QSC Part Description Qty. 12345 Tools and materials needed • Philips screwdriver • Diagonal cutters • Tie wraps • Needle-nose pliers • Adhesive rubber foot (one per channel), QSC part # QQ- QQQQQQ-QQ or equivalent • 5/64” hex (Allen) key • 11/32” nutdriver or socket wrench • Isopropyl alcohol and a small brush Disassembly Removing the top cover 1. Disconnect the amplifier from AC power and allow at least 10 minutes for internal voltages to bleed down. 2. A total of 18 screws—six with pan heads and twelve with flat heads—hold the top cover to the chassis. Using a Philips screwdriver, remove them and set them aside. See Figure 2.1. 3. Lift the top cover up at the front until it clears the side rack ear pieces, then lift it off the chassis. If the front of the cover is bent or dented, make sure the front edge clears the two display board headers. Figure 2.1. Removing or installing the top cover.

Removing or installing the display board. 2.3 AC line filter The AC line filter is an important part of the amplifier because it reduces noise and interference from the internal switching circuitry to prevent its radiation into the AC wiring. It also contains part of the housekeeping supplies for the two audio modules; without the housekeeping supplies, the amplifier’s power supply modules will not start up even if they are in working order. The line filters are the same among the three amplifier models, but the 120-volt and 230-volt versions are not interchangeable. See Figure 2.8.

The control circuitry in turn enables the power supply module to operate. Thus, a power supply module normally will not operate when it is not connected to an audio channel. The remote control circuit shown in Figure 2.9 allows the power supply module to operate without an audio channel module connected. This is useful for verifying the power supply’s operation independently of other amplifier circuitry. Tools and materials required: • Soldering iron • Rosin-core solder (60/40 or 63/37 eutectic type) • Long-nose pliers • #1 and #2 Philips screwdrivers • Thermal grease (heat sink compound) • Small diagonal cutters • Desoldering equipment or solder braid POWER SUPPLY TEST REMOTE CONTROLLER • Micro-torque wrench with 9/64” Allen (hex) and #1 Philips bits If fuse F1 on the power supply module’s printed circuit board (PCB) is blown, you will also need a 1A 250V 5×20 mm slow-blow fuse (QSC part # MS-000113-00) to replace it with. Also, the alumina insulator between the diodes and the heat sink is very fragile and often breaks when the diodes are removed; replace it with QSC part # PL-000085-00.

2. Remove the MOSFETs from the heat sink. Thoroughly clean the old thermal grease off the heat sink. Apply fresh thermal grease to the new MOSFETs (QSC part # QD-000188-00) and attach them to the heat sink. Make sure the new MOSFETs are correctly oriented. One end of each MOSFET has a mounting hole, while the other has an open-ended slot (see Figure 2.9). Each MOSFET must be mounted so the slot end faces away from the diode end of the heat sink (see Figure 5.11). Try to get the MOSFETs evenly spaced and as close to perfectly in line as you can. The silk screen print on the circuit board (see Figure 5.12) shows the correct orientation. Tighten the MOSFET mounting screws to 32–35 lb-in (3.6–4.0 N-m) torque. Do not over-torque them. 3. Remove the four diodes on the circuit board (D1, D2, D7, and D8). See Figure 2.12. 4. Check the value and rating labeled on capacitor C20 (see Figure 2.13). If it is not a 0.1 μF 250V capacitor (early modules will have the original 0.047 μF 400V component instead), replace it with QSC part # CA-410009-00. 5. Remove resistors R5 through R8 (see Figure 2.11) and replace them with 4.75Ω 1⁄4-watt resistors (QSC part # RE-.47501-10). 6. Set the MOSFET and heat sink assembly upside-down and place the PCB on top of it. Make sure all the threaded holes in the heat sink and the MOSFETs line up exactly with the holes in the board. If any MOSFETs don’t line up, reposition them so they do because misaligned mounting screws can damage them when tightened. Make sure the fishpaper strip is in place, and then reattach the MOSFET and heat sink assembly to the PCB. Make sure you use the correct screws and washers in each location. Tighten the four heat sink screws to 32–35 lb-in (3.6–4.0 N-m) torque and the MOSFET mounting screws to 12 lb-in (1.4 N- m). Do not over-torque them. CAUTION: Overtightening its mounting screws will destroy a MOSFET. When tightening a screw, use the split lockwasher as a visual guide; as soon as it is flattened, the screw is tight enough. Plug the thermal sensor lead onto its two pins on the circuit board. 7. Clear any solder from the circuit board holes for the four diodes. Apply a thin coating of new thermal grease to both sides of the alumina strip and set it in place on the heat sink. Insert the four new diodes (120V models: QSC part # QD-000183-00; 230V models: QSC part # QD-000182-00) into their holes in the PCB, but do not solder them in place yet. Then set the two mica insulators in place over the diodes (they will overlap in the middle), and clamp and fasten the diodes to the heat sink; tighten the screws to 32–35 lb-in (3.6–4.0 N-m) torque. Do not over-torque them. As you do (from between the diodes and the heat sink); it is extremely fragile, so it is best to replace it during reassembly with a new one. Then remove the 16 screws that attach the MOSFETs to the printed circuit board (PCB); if the MOSFETs are blown, some of the mounting screws may be melted or damaged. The new MOSFETs come with new mounting screws with captive washers, so there is no need to save old ones for reuse. Remove the other four mounting screws so that the heat sink assembly is free from the circuit board. Set the hardware aside. Find where the twisted wire lead from the heat sink’s thermal sensor attaches to a pair of pins on the board, and unplug it. Detach the gate drive cable, which is an 8-conductor ribbon cable that plugs into an 8-pin header. Lift the heat sink and MOSFET assembly from the board. If the strip of fishpaper (Figure 2.11) remains stuck to the PCB, leave it there; if it comes loose, set it aside for re-assembly later. “Diode” end of heat sink Figure 2.10: The heat sink assembly, with all four MOSFETs attached. The “diode” end of the heat sink is at right; the slots in the MOSFETs would face to the left. Figure 2.11. The silk screen on the circuit board shows the correct orientation of the MOSFETs. This photo also shows the four resistors (R5–R8) to be replaced.

this, make sure the diodes are straight and evenly spaced, and reposition them if necessary. 8. Solder the four diodes to the circuit board. 9. Reattach the gate drive cable. 10. Check the fuse (see Figure 2.14). If it is blown, replace it with a slow-blow 1A 250V 5×20 mm fuse (QSC part # MS-000113-00). 11. Repeat the procedure for the other channel’s power supply board if it also has failed or is to be updated. Suggestions for troubleshooting If you are repairing a failed power supply module and not simply upgrading a working one, you should determine whether other components have also failed. Typical collateral failures around PFC power supply module failures include: Blown high rail diodes: Check D12 and D14 for sooty or blackened thermal grease around their edges or for any other signs of damage. If you suspect that they might be damaged, remove them from the circuit board and check them with the diode test function on a DMM. Replace them if necessary (QSC part # QD-000126-00). These diodes are clamped onto the other heat sink, at the end next to the power transformer. If you remove the diodes, thoroughly clean away the old thermal grease from that portion of the heat sink and from the mica insulators; apply fresh thermal grease when you reassemble or replace them. Blown driver ICs: The two MIC4452BN MOSFET driver ICs, U1 and U3, are under the MOSFET heat sink. Frequently, when MOSFETs fail, the driver IC associated with the transistor(s) fails, too. The IC’s QSC part # is IC-000064-00. Fuses: Conditions that cause the MOSFETs to fail also frequently cause the fuses on the AC line filter to blow. The filter circuit board runs along the side of the amplifier between the AC power cable and the AC power switch. Each channel has two fast-blow ceramic AC fuses, for a total of four (120V models: 125V 25A, QSC part # MS-000112-00; 230V models: 250V 15A, QSC part # MS-150250-FU). Check them and replace any that are blown. Also on the AC line filter board are the housekeeping supplies for each channel; if they do not work, the channels will not start even if the power supply modules are in perfect working order. The housekeeping supplies each use a 250V 1A slow- blow fuse (QSC part # MS-000113-00). Capacitor C20 Figure 2.13. Capacitor C20 may also need replacement. See the text. Figure 2.14. Fuse F1 may need replacing.

Fuse F1 Adjusting and calibrating the power supply module Adjusting and calibrating the power supply card will help ensure the success of the repair; this portion of the service bulletin describes a series of five procedures for doing so. Because of the specialized nature of the power supply fixture required for these procedures, it can only be performed at the QSC factory by trained personnel. Follow these procedures exactly and in order. There are four trimpots, VR1–VR4 (see Figure 2.14), on the controller card that must be adjusted correctly before reinstalling the power supply in the amplifier: VR1 On the PL 9.0PFC, this trimpot sets sets VOUT/26.6. VOUT/32; on the PL 6.0PFC, it VR2 This trimpot is for balancing the transformer to the PFC circuitry. VR3 This trimpot sets the maximum 2-ohm output power. For the PL 9.0PFC, it will be set for 4500 watts @ 2 ohms at 2 kHz; for the PL 6.0PFC, it will be set for 3600 watts @ 2 ohms at 2 kHz. VR4 This trimpot sets the power supply’s idle voltage. For the PL 9.0PFC, it will be set for 191.3 volts DC; for the PL 6.0PFC it will be 166.5 volts DC. Tools and materials needed: • PFC power supply fixture with external power supply and CMP (Control-Monitor-Power) box • Two digital multimeters (DMM #1 and #2) with clip-on leads • Digital multimeter (DMM #3) with clamp-on AC current probe • 0–240 VAC VariacTM, PowerstatTM, or similar variable AC transformer; 60 amperes or higher rating, with RMS voltage and current metering • 120 VAC power (for the fixture’s housekeeping supply) • Four-channel oscilloscope with ×1/×10 probes • Oscilloscope with differential probe (optional; see • step Small 10 pocket-type of the VOUT flat-blade procedure) screwdriver • Grounded anti-static work surface • Audio Precision (AP) workstation with PFC test procedure files* and 2-ohm load resistor banks (mimimum power handling capacity: 1250 watts per 8-ohm resistor; 5000 watts total in 2-ohm configura- tion). *The four AP test procedure files are available on the QSC Technical Support CD-ROM: Pfcxf.tst; Pfcpwr2k.tst; Pfcpwr20.tst; and Pfctherm.tst. The PFC power supply fixture The PFC power supply fixture is a special test bed for PowerLight 6.0 and 9.0 supply modules. It has the necessary connections and indicators for adjusting, calibrating, and testing the modules. It also contains one audio channel of a PowerLight 9.0 to allow testing of the module’s capability to power an actual amplifier channel. The fixture is custom built by QSC. Front panel switches and indicators From left to right (Figure 2.14): • Power switch. For the AC lines to the power supply module being tested. • Power indicator. It lights when the fixture is connected to AC power and is turned on. • Blown fuse indicator.

DC supply AC connection Solid- state fuse Power switch for housekeeping supply. Switches and LED indicators The CMP box The CMP box has two digital panel meters that monitor AC voltage and current and a solid-state electronic AC fuse that can be set to trip specific current levels from 0 to 100 amperes. To set the current trip level, flip the trip set switch down; the AC ammeter will then read the trip current setting. Use the trip set knob to adjust the desired trip point, then flip the switch up. The BNC jack provides an AC voltage proportional to the AC current: 100 mV RMS = 1.0 ampere RMS. This is useful in the transformer balancing procedure because it allows the use of an external voltmeter with finer resolution (>3 decimal places) than the panel ammeter has. Important note about repaired PFC power supply modules After repairing a failed power supply module that had already been calibrated before its failure, either in produc- tion or in Technical Services, the VOUT/32 and VOUT @ idle voltages in Procedure 1 only need to be checked and not fully adjusted, unless the measured high rail voltage is not 191.3 volts, ±1.5 volts, for the PL 9.0 or 166.5 volts, ±1.5 volts, for the PL 6.0. If the high rail voltages are outside this range, then the module will require full adjustment and calibration. Gate drive cable Figure 2.20. The CMP box. The variable AC outlet for the test fixture is on the back of the box. Figure 2.21. The gate drive cable for the MOSFETs. Disconnect it here for the VOUT procedure. 9. Connect DMM #1 to one set of the parallel DC on the back of the fixture. Connect DMM #2 to Vthe OUT controller terminals card, with the ground or reference lead on the tab of U8, a +12V regulator, and the hot lead on the left leg of capacitor C34. On the board, this point is labeled “VOUT/32.” 10. Note: this step is optional because the replacement diodes specified in this bulletin do not have the leakage problems that many of the original fast diodes had. Through a differen- tial probe, connect an oscilloscope input between resistor R31 (labeled “OSC”) and ground; this will allow you to view the output of the diodes to see if any are leaky. 11. Turn the fixture power switch on. Turn up the Variac gradually until DMM #1 reads 190 volts DC (for the PL 9.0) or 166 volts (for the PL 6.0). You don’t need to measure the AC voltage from the Variac yet. 12. Adjust VR1 to obtain a reading on DMM #2 of 5.94 volts DC (for the PL 9.0) or 6.20 volts DC (for the PL 6.0). 13. Flip switch the lights ISET switch green down. or should be rejected for If the LED indicator next to the orange, controller ISET board is good; if red, it is bad and replacement or repair. 14. Turn down the Variac all the way. Turn off the fixture’s AC switch. Unplug the external supply’s AC line from the Variac. 15. Set leads the from ISET the and controller VOUT/32 switches card. Trip set switch up: reads AC current; Trip set switch down: reads trip current setting Adjusts trip current of solid state fuse 0–280 VAC in from Variac down. Remove DMM #2’s 16. Wait a few seconds for the capacitors to discharge and DMM #1’s voltage reading to drop to 60 volts or less. Procedure 2 of 5: Adjusting idle voltage 1. Re-attach the gate drive cable on the power supply module. Also, disconnect the five DC rail output wires on the right end of the module from the lower barrier strip and attach them to the corresponding screw terminals on the upper barrier strip. Make sure the screw connections are tight and secure. 2. Turn the fixture’s AC switch on and turn the Variac up to the appropriate AC voltage: 120 volts AC for a 120V module, or 230 volts AC for a 230V module. The power supply will turn on and begin to draw current when the AC voltage reaches about the halfway point. 3. Adjust VR4 to obtain the a reading of 191.3 volts DC (for the PL 9.0) or 166.5 volts DC (for the PL 9.0) on DMM #1. 20 QSC Audio Products, Inc.

Procedure 3 of 5: Adjusting transformer balance This is done in three stages. In the first two, watch the trans- former flux “bubble” waveform on the oscilloscope, and on the third, adjust the AC current to a minimum. To prevent overcurrent cutback due to undervoltage, adjust the Variac to 130 volts for 120-volt modules or 260 volts for 230-volt modules. 1. Set the CMP box’s electronic fuse to a trip threshold of 20 amperes (for a 120V module) or 10 amperes (for a 230V module) and turn on the fans. 2. Start the PFC test file (Pfcxf.tst) on the AP workstation. It will put out a 2 kHz sine wave at 0.1 volt RMS and will switch the load resistance to 2 ohms. Turn the fixture’s gain control all the way up. 3. Step the signal level up in 0.1 volt increments and watch the transformer flux “bubble” signal on the oscilloscope (vertical scale: 20 or 50 V/div; horizontal scale: 1 or 2 ms/div; ×1 scale). At each step, adjust VR2 to get a smooth, balanced signal. See Figure 14. There should be no spurious oscillations or noise visible. 4. When the audio signal reaches a particular level, the CMP box’s electronic fuse will trip. Set the audio signal back to 0.1 volt. 5. Reset the trip point to 40 amperes (for a 120V module) or 20 amperes (for a 230V module) and repeat steps 2 and 3. The electronic fuse should trip at about 2.8 kW of output (measured on the AP), with approximately 1.4 volts input. 6. Reduce the AP’s signal level to 0.1 volt. Reset the electronic fuse and increase the signal level so that the output is about 2.5 kW. Gently adjust VR2 to null the AC current on DMM #3 to a minimum. 7. Turn the Variac down to zero and set the electronic fuse to 60 amperes. Procedure 4 of 5: Adjusting 2-ohm limits 1. If this is a brand new module (not a repair), set VR3 to approximately 4 o’clock. If it is a repair or has otherwise already been calibrated at some time, leave VR3 alone until after the first power sweep. 2. Set the Variac to 130 volts (for 120V modules) or 260 volts (for 230V modules). 3. Run the AP test file (Pfcpwr2k.tst) for a 2-ohm power sweep test at 2 kHz. 4. Watch the power sweep on the AP monitor and see where the power cutback occurs. The target output power level at 2 kHz is about 4.6 to 4.7 kW for the PL 9.0 or 3.6 to 3.7 kW for the PL 6.0. If the cutback point is not in the target range, carefully adjust VR3 and then repeat the power sweep. It may take more than two or three tries to get the right setting. CAUTION: During the power sweep, keep a finger on the reset switch of the CMP box. If anything abnormal happens, such as power cutback at a low level, or audible noise from the supply module’s transformers, immediately flip the reset switch down and hit F1 on the AP computer keyboard to abort the sweep test. If you stopped the test due to transformer noise, go back and start over at the transformer balancing procedure. If you had not aborted the power sweep, in a short time you would have destroyed the MOSFETs. If you stopped the test for any other abnormality, you must troubleshoot and repair the supply module before continuing. 5. Load the AP test file Pfcpwr20.tst, which will change the signal frequency to 20 kHz, and repeat step 4. This time, verify that the power cutback does not occur until approximately 4.5 kW for the PL 9.0 or 3.6 kW for the PL 6.0. 6. After competing the power sweeps, press F1 on the AP computer keyboard. Procedure 5 of 5: Thermal test 1. On the AP workstation, load the thermal test file Pfctherm.tst. It should select the Pseudo (pink noise) waveform at 2.7 volts RMS amplitude. Make sure the fixture’s gain control is turned up full. Load the fixture output with the 2-ohm resistance and shut off the fans. 2. The power supply module should shut down within one minute. The PROTECT indicator LED on the front panel will light. 3. After the module shuts down, turn on the fans and await its

Turn down the Variac to zero. Turning off the fixture’s AC switch will automatically bleed the capacitors down. Disconnect the module from the test fixture and set the AP workstation back to sine wave and 0 volt RMS. 2.5 AC voltage conversions WARNING: Regulatory agencies require that any operating voltage conversions from 120 volts to any other voltage be done only by QSC’s factory service. Any other operating voltage conversions may be done only by a QSC-authorized service center or international distributor. The power supply modules and line filter modules in the PowerLight 6.0 II, PowerLight 6.0PFC, and PowerLight 9.0PFC are made for specific AC line voltages; they cannot be converted from one to another. To convert an amplifier from120 to 230 volts AC or vice-versa requires replacing both power supply modules and the AC line filter. For this reason, it is seldom economically justifiable to convert one of these models. 2.6 Bias adjustments These three amplifier models have a trimpot for bias adjustment on each audio channel. However, adjusting it is far more complex than on most amplifiers, so it should only be done when working on the module at board level, or as an emergency measure if the module is running too hot at idle. 22 QSC Audio Products, Inc.

3. Troubleshooting Because of the high complexity of the circuitry used in the amplifiers covered by this manual, most, if not all, of your troubleshooting efforts will be at board level. Proper component- level troubleshooting and service will also usually require specialized test fixtures that may not be economically sensible to have unless you do a high volume of service work on these amplifiers. See the Servicing chapter of this manual for informa- tion on these fixtures. 3.1 Initial check When first checking the operation of a suspect amplifier on the bench, always turn your variable transformer down to zero before plugging the amplifier in. After you turn the amplifier on, gradually turn up the AC voltage as you observe the amplifier’s behavior and its current draw; this will help you determine what, if anything, is wrong with it. If you see or smell smoke, flames, or any other signs of short circuits or excessive current draw, quickly turn the AC back down to zero. If no such problems occur, it is usually safe to turn the AC up to the amplifier’s full operating voltage for further testing. The following procedure will help you determine if the amplifier has a problem and if so, where it may be located. Starting at zero volts 1. Start with the variable transformer at zero. 2. Connect an AC voltmeter to monitor the transformer output and an AC ammeter to monitor the current delivered to the amplifier. 3. Connect the amplifier to the output of the variable trans- former. 4. Turn on the amplifier. LED activity starts 5. Gradually turn up the AC voltage. When it reaches about 25% of the amplifier’s operating voltage (30 volts for a 120-volt model or 60 volts for a 230-volt model), the power LEDs on both channels should start to flicker. By the time it reaches about 40% (50 volts for a 120-volt model or 100 volts for a 230-volt model), both power LEDs and both protect LEDs should be on. 6. Continue increasing the AC voltage. When it reaches about 70 volts (120-volt model) or 140 volts (230-volt model), both protect LEDs should go out and all four fans should start up. Check current draw 7. At this point, the current draw for a PowerLight 6.0PFC or PowerLight 6.0 II should be about 2 A or less for a 120-volt model or 1 A or less for a 230-volt one. For a PowerLight 9.0PFC, it should be about 2.5 A or less (120-volt model) or 1.25 A or less (230-volt model). 8. If all is well, you can safely increase the AC voltage to the amplifier’s normal operating level and test its audio perfor- mance. Once the AC voltage is at full, the amplifier should behave normally. On the left side of the front panel, the two power LEDs should be lit, while the standby and protect LEDs should not. On the right, the signal, -20 dB, -10 dB, and clip LEDs should light only in response to an output signal. If they do not, continue by following the preliminary troubleshooting guide. 3.2 Preliminary troubleshooting Abnormal behavior of the amplifier indicates some problem in one or more of its parts. You can use the observed patterns of this behavior to help deduce where the problem lies. The amplifier has two channels with independent power supplies; a defect may exist on one channel that does not affect the other. Power, Standby, and Protect LEDs: None lit on one or both channels • The main fuse for the affected channel(s) may be blown. The main fuses are located in the line filter assembly and are accessible when the amplifier’s top cover is removed. • The audio module’s housekeeping supply is not working on the affect channel(s). This is a rare failure because the house- keeping supply has very reliable protection against short circuits and other possibly destructive situations. Without its housekeeping supply, though, the audio module cannot signal the power supply module to turn on. Protect LED lit • If the Protect LED lights steadily, without interruption, the power supply module is not working. • If the amplifier is hot, it has probably overheated and will stay in protect until it cools down to a safe temperature. Amplifier endlessly cycles on, into protect, and then off, and over again • There is a defect in the audio module—probably in the output circuitry—that prevents the power supply module, as it starts up, from reaching its proper rail voltages or places DC on the output. When this happens the channel immediately switches into protect, and then the power supply resets and tries to start again.

Technical Service Manual 23 PowerLight 6.0 II, PowerLight 6.0PFC, and PowerLight 9.0PFC 3.3 Further troubleshooting This procedure allows you to further isolate the problem and determine which board or module is defective. Start at zero volts 1. Turn the variable transformer to zero and turn the amplifier off. Open the amplifier 2. Remove the top cover of the amplifier. See the Servicing chapter for instructions and diagrams. 3. Check the continuity of the two main fuses, located at the top of the line filter assembly near the front of the amplifier. Replace any that are open. Ramp up the AC voltage 4. Turn up the AC voltage to about 30 volts (120-volt model) or 60 volts (230-volt model). 5. Using pliers, pull the connectors for the two housekeeping supply wires off of the audio module of the affected channel. Measure the voltage between the wires. It should be approximately 40 volts DC. If the voltage is significantly lower or is not there at all, there may be a problem with the portion of the housekeeping supply that is on the line filter assembly. 6. If the voltage is good, reconnect the housekeeping supply wires. 7. Disconnect the latching connector on the cabling that goes to the input board. If the channel now starts up, then the problem was on the input board—perhaps a defective op amp; replace or repair the input board. 8. If disconnecting the input board did not make the channel start up, reconnect it and turn the amplifier off. 9. Disconnect the power supply control ribbon cable from the 8- pin header on the audio module. Attach the power supply remote controller (See the section on servicing power supplies in Chapter 2) to the ribbon cable. 10. Loosen the screw terminals of the five power supply wires at the front of the audio module. Remove the wires from the terminals and make sure they are arranged so none of them will short out against anything. 11. Turn switch S1 on the remote controller to on and turn the amplifier on. The LED on the remote controller should glow green. 12. Increase the AC voltage to 65 volts (120-volt model) or 130 volts (230-volt model). 13. Measure the voltages on the supply wires 1 through 4, using wire 0 as a reference. 24 QSC Audio Products, Inc. TD-000083-00 4.
