Multiplexer Hardware Installation 1 Welcome Thank you for purchasing a Crown IQ mixer/multi- plexer. IQ mixer/multiplexers are intelligent mixers with special signal routing capabilities. Their intelli- gence stems from a powerful onboard microproces- sor which enables them to be controlled and monitored by a Crown IQ System®. Each input and each output can be individually controlled and, with their distributed intelligenceTM capability, continue to operate even when an IQ System is not connected. In addition to two main outputs (one for each chan- nel), each model has a second set of ÷busš outputs which are switched on/off by a relay. This enables many mixer/multiplexers to be connected to a com- mon audio bus without loading it down. They are designed to work as stand-alone units in a small audio system or as modules in a large audio sys- tem. Three different models are available to serve a wide variety of needs. The MPX-6 TM and SMX-6 TM models operate as 6x2 mixers. The AMB-5 TM can operates as a 5x2 mixer. Multiple units can be connected together to form larger mixers. For example, a MPX- 6 and SMX-6 can be connected together to form a single 12x2 mixer. They can also be connected as a 6x4 mixer. The MPX-6 is the simplest of the three models. It provides basic mixing capabilities. All control and monitor functions are handled by the IQ System. The MPX-6 does not have the automatic mixing capability of the other models because it does not have input sensing. The SMX-6 is more sophisticated because it has sensing ability. A sensing circuit is located at the beginning of each input to sense the input signal level ahead of any signal processing. Similar sen- sors are located at each output. These sensors, along with its onboard intelligence, enable the SMX- 6 to perform many versatile functions like automatic mixing, compression, and automatic level control. The AMB-5 has the same functions as an SMX-6 plus it has the ability to sense the ambient sound level and automatically adjust its output level ac- cordingly. In this way it serves as the ultimate automatic level controller. Input 6 is dedicated as the sensing input, leaving five to function normally as a 5x2 mixer. Unlike the SMX-6, signal processing is only available for Channel 1. Channel 2 functions like an MPX-6. Rev. 0 1.1 Options In a standard IQ System, the IQ components like the mixer/multiplexers are connected to the system via the Crown Bus. The Crown Bus is a serial com- munication loop which carries IQ commands and data. IQ mixer/multiplexers are also able to bypass the Crown Bus and connect (one at a time) directly to a computer (PC compatible or Macintosh®). Once configured, the mixer/multiplexers can be discon- nected and allowed to operate by themselves. Option 1 allows an AMB-5, MPX-6 or SMX-6 to con- nect to a host computer and serve as a Crown Bus interface between the computer and other IQ com- ponents. This eliminates the need to purchase a separate IQ interface (IQ-INT) for a small IQ Sys- tem. Option 4 allows an SMX-6 (only) to connect to a Crown Local Net loop. The Crown Local Net is a communication subsystem within an IQ System. Using it, two or more SMX-6s can communicate between themselves to keep track of the total num- ber of open microphones. This information can then be used to prevent feedback when more mics are open. Note: Options 2-3 are not presently available. 1.2 Unpacking Please unpack and inspect the unit for any damage that may have occurred during transit. If any dam- age is found, notify the transportation company im- mediately. Only you, the consignee, may initiate a claim with the carrier for damage resulting from shipment. Crown will cooperate fully as needed. Save the shipping carton as evidence of damage for the shipper’s inspection. Even if the unit arrived in perfect condition, as most do, save all packing materials so you will have them if you ever need to transport the unit. NEVER SHIP THE UNIT WITHOUT THE FACTORY PACK.

3 Hardware Installation The installation of an IQ mixer/multiplexer consists of two major parts: installing the hardware and con- figuring the software. This manual deals only with hardware installation. Refer to the appropriate soft- ware manual for instructions in setting up and oper- ating your unit. Provide adequate cooling if the unit will be used in a hot environment. Allow one empty rack space (1.75 inches or 4.4 cm.) between each unit if more than four units will be stacked in a cabinet. Each empty rack space should be sealed with a blank rack panel. The hardware installation is divided into 4 steps: 1) connecting to a host computer, 2) connecting to the Crown Bus, 3) connecting the audio inputs and outputs and 4) connecting auxiliary devices. 3.1 Connecting to a Host Computer (Step 1) An IQ host computer is an IBM® PC compatible or Apple® Macintosh computer which is used to con- figure or control/monitor part or all of an IQ System. Depending upon the design of your IQ System, it may or may not require a host computer during normal operation. Page 10 IQ Mixer / Multiplexer Hardware Installation RS232 DSPI ENABLE ENABLE CH1 CH2 CHow the mixer/multiplexer will be used will deter- mine whether or not it will need to be connected directly to a host computer. If the unit will be con- nected to the Crown Bus it will not need to be connected directly to a host computer. The following circumstances require connection to a host com- puter: • If a Crown Bus will not be used, the mixer/mul- tiplexer will need to be connected to a host computer so the software inside the unit can be configured. Afterward, if manual control is not required, the host computer can be discon- nected. • If the mixer/multiplexer must be configured be- fore it is installed into an IQ System, it must be connected directly to a host computer for con- figuration. The onboard battery of the unit will maintain its software configuration for up to 60 days without it being plugged into an AC source. • If the mixer/multiplexer will be used as an IQ interface (Option 1) it will need to be con- nected directly to a host computer. One of the advantages of connecting directly to a host computer is that a separate IQ interface (IQ- INT) is not required. If you plan to configure the unit Rev. 0 1 P OOLS UBN WOR2P OOLS UBN WORCDSPI ENABLE ODEP ODEP ENABLE IOCSPI POWER POWER OFF CH1 CH2 OFF ENABLE CH1 CH2 IOCSPI ODEP ENABLE POWER CH1 CH2 OFF ODEP IOCSPI POWER OFF ENABLE CH1 CH2 IOCSPI ODEP ENABLE POWER CH1 CH2 OFF ODEP IOCIOCSPI SPI POWER OFF Fig. 3.1 An IQ System with a PC Host Computer and Two Mixer/Multiplexers

IQ Mixer / Multiplexer Hardware Installation while it is connected to the Crown Bus, skip ahead to Section 3.2. There are two main communication standards sup- ported by the unit for serial communication with a host computer. They are RS232 and RS422. RS232 is commonly used with IBM PCs and com- patibles. Because it uses unbalanced signal wiring, it cannot be used for distances over 50 feet (15.2 m). RS422 is commonly used with Macintosh comput- ers. It uses balanced signal wiring and can be used for distances up to 2,000 feet (610 m). Although uncommon, RS423 communication can also be used. It uses the unbalanced transmitter (TXD) wiring of RS232 and the balanced receiver (RXD) wiring of RS422 to provide signal ground isolation between the transmit and receive lines. With a proper cable it can be used over a greater distance than RS232...but a shorter distance than RS422. For details contact either Crown Tech. Sup- port or Amcron Tech. Services (see page 22).

Instead use an un- twisted cable or ribbon cable. Twisted-pair wire can be used for RS422. 3.1.1 Communication Standards and Parameters Before communication can take place between the unit and a host computer the communication stan- dard must be selected and the communication pa- rameters must be set with switches accessed through an opening in the side of the chassis. (Fig- ures 2.2 and 3.5) Caution: Be sure to disconnect the AC power from the unit before selecting a different communication standard or changing the parameters. IBM PC-compatible computers typically have an RS232 serial port, so the communication standard switch should be moved to the right (Figure 3.5). With a Macintosh host computer, the standard is usually RS422, and the communication standard switch should be moved to the left. In the rare event that RS423 communication is used, set the switch to the RS422 position. Setting the communication parameters for RS232 and RS422 serial communication is accomplished using the six segment baud rate and parity DIP switch in Figure 3.5. The first four switches select the baud rate and the last two set the parity. Use the fastest baud rate possible. The highest baud rate supported by the unit is 19.2 K baud. Parity check- ing is not presently supported and should be OFF. The odd/even parity bit doesn’t matter when parity is switched OFF. The unit has been factory set to 1 stop bit and 8 data bits. Important: The communication standard and param- Page 11

BAUD RATE & PARITY SETTINGS MAC PC Fig. 3.5 Selecting the Communication Standard and Parameters eters of the mixer/multiplexer and the host computer must be the same. Any mismatch will prevent com- munication from taking place. The communication parameters of the host com- puter are set by the IQ software. This is true for both PCs and Macintosh computers. Please refer to the appropriate software manual for details. Here are some important guidelines when configur- ing serial communication: • Use the same communication standard at each end. If the unit is set for RS232, the computer must also be set for RS232. (Refer also to the appropriate IQ software manual.) • Use the same communication parameters at each end. The unit and the computer must be set for the same baud rate and parity check- ing. • Use the highest baud rate possible but be aware that the communication circuitry (UART) in some PCs cannot function over 9600 baud. (IQ mixer/multiplexers can be set as high as 19.2 K baud.) • If the host computer fails to communicate with the unit and the communication standard and parameters are set correctly, try reducing the baud rate of both the unit and the computer. • If communication problems persist, check the serial cable for improper wiring or possible shorted or broken wires. • For further assistance call either the Crown Technical Support Group or Amcron Technical Services Dept. (see page 22 for telephone numbers). 3.2 Connecting to the Crown Bus (Step 2) The Crown Bus is a serial communication loop de- signed to transmit IQ commands and data. As a communication standard it is independent of the wiring system used. This flexibility is a great strength, enabling a Crown Bus loop to be wired with either fiber optic cabling or with inexpensive twisted-pair wire, whichever the installation re- quires. A single IQ System can have more than one Crown Bus loop. To function properly, a Crown Bus loop must be unbroken. 3.2.1 Setting the IQ Address Before installing a mixer/multiplexer on a Crown Bus loop, it must be given a unique IQ address. This address will be used by the IQ System when- ever it communicates with the unit. The 8-segment DIP switch shown in Figure 3.5 is used to set the IQ address. No two IQ components of the same model which are connected to the same Page 12 1 2 3 4 5 6 7 8 1 2 4 8 16 32 64 128 BAUD RATE PARITY IQ ADDRESS BAUD RATE & PARITY COM STANDARD OFF ON RS232 RS422 1 2 3 4 5 6 IQ Mixer / Multiplexer Hardware Installation 1 2 3 4 5 6 19200 9600 4800 BAUD RATE 2400 1200 300 150 ON PARITY ODD OFF EVEN Rev. 0

IQ Mixer / Multiplexer Hardware Installation Crown Bus can have the same address. Suppose, for example, an IQ System has two Crown Bus loops as shown in Figure 3.1 and an SMX-6 is installed in loop 1 and given IQ address 77. No other SMX-6 can be given the same address in Crown Bus loop 1. However, an SMX-6 can have the same address if it is installed in loop 2. Different IQ components can have the same address and be in the same Crown Bus loop. In the previous example, an AMB-5 could be installed in loop 1 and use IQ address 77 because it is not an SMX-6. A valid IQ address is any number from 1 to 250. Do not use a number higher than 250 since they are reserved for special use. An address of ÷0š (zero) should not be used. The IQ address is determined by adding the values of each segment of the DIP switch which is turned on (pushed down). Figure 3.5 shows the value of each DIP switch segment. For example, if the desired unit address is 1, only switch 1 should be down. If the desired unit address is 217, switches 8, 7, 5, 4, and 1 should be down (128+64+16+8+1=217). See Appendix A for list of all valid DIP switch settings. If the IQ interface used is an IQ-INT, the system can have up to eight separate Crown Bus loops. This will enable the audio system to be divided into different zones, each with its own Crown Bus loop. Dividing the IQ System into multiple Crown Bus loops has advantages and disadvantages which are listed be- low: Multiloop Advantages • A break in communication in one loop does not affect other loops. • Over 250 IQ components of the same model can be use in a system. • The same IQ address can be used more than once (once per loop per model). Single Loop Advantages • The IQ System can send and retrieve data faster in a single loop. • ÷Real timeš level display of a greater number of units is possible. 3.2.2 Crown Bus Wiring The Crown Bus is implemented in IQ mixer/multi- plexers as a 20 milliamp current loop operating at 38.4 K baud so that it can function with inexpensive twisted-pair wiring. If fiber optic wiring is required contact Crown Tech. Support or Amcron Tech. Ser- Rev. 0 vices (see page 22) for information on adding the appropriate transceivers. Here are some guidelines for twisted-pair wiring: • Use shielded twisted-pair wire at least 26 AWG in size. The wire should be of good qual- ity and should NOT have high capacitance (30 picofarads/foot or less is good). Shielded wire is recommended for situations where interfer- ence is a problem. (West Penn 452 or an equivalent wire works well.) The shield serves two purposes: First, it helps prevent the IQ data signal from transmitting to nearby audio wiring. Second, it helps prevent outside RF from interfering with the data signal. However, in most cases interference is not a problem and, since unshielded wire has lower capaci- tance, it is a better choice. • If shielded wire is used, connect the shield only to the input connector. • Add an IQ Repeater for very long loops...greater than 1,000 feet (305 m)...or when required by high-capacitance wire. Al- though we recommend adding a repeater for loops longer than 1,000 feet, it is often pos- sible to go 2,000 feet (610 m) or more. The most significant characteristic of the wire is its capacitance. The lower the capacitance, the longer the loop can be. Unshielded wire typi- cally has less capacitance. • Never use the ground wire in a mic snake line. It may sometimes be convenient to run Crown Bus data signals to and from stage monitor amplifiers along unused wire pairs in a mic snake. If this is done, do not use the ground wire which is normally connected to pin 1 on an XLR connector or data noise will be Mixer/Multiplexer 1 Mixer/Multiplexer 2 1 2 3 4 1 2 3 4 Cable connectors are numbered as they appear from the front.

Note: Because typical mic cables have high capacitance, the maximum possible Crown Bus loop distance will be less. Outside RF interference is seldom a problem for a Crown Bus loop...especially if shielded twisted-pair wire is used. However, there are extreme situations when fiber optic wiring is recommended. For ex- ample, locating a Crown Bus loop next to an AM radio transmission line may require fiber optic ca- bling. An extremely long Crown Bus loop distance (greater than 10 miles) may also require fiber optic cabling. Some examples of twisted pair wiring follow. Figure 3.6 shows point-to-point wiring for the Crown Bus using two female removable barrier block connec- tors: Some IQ components use separate 5-pin and 4-pin DIN connectors for Crown Bus input and output wiring. Connecting to them is shown below: The IQ components in each Crown Bus loop are wired in series. The output of one IQ component ÷loopsš to the input of the next and so on. This is shown in Figure 3.9. Fig. 3.10 An Audio Input Section Pro audio equipment Semi-pro or consumer equipment 3.3 Connecting the Audio Ins & Outs (Step 3) IQ mixer/multiplexers have 6 mic/line inputs and 2 stack inputs. (Input 6 of the AMB-5 is dedicated for ambient sensing and is discussed in Section 3.3.2.)

IQ Mixer / Multiplexer Hardware Installation It is also possible to connect more than one ambient sensing microphone to the sense input. This can be accomplished by taking advantage of the manual mixing function of Channel 2. Simply connect each ambient sensing microphone to one of the five regu- lar inputs of the AMB-5 and use the IQ software to assign each of them to Channel 2 only. Switch the sense input to the line-level position (L) and connect the main audio output of Channel 2 to it. Use the IQ software to control the level of the ambient sensing microphones. The microphones which are located in more critical areas can be set to a higher level so they will trigger the level controller first. Be sure the microphone has adequate sensitivity for the spectral content of the ambient sound. For ex- ample, a microphone with a bandwidth designed solely for speech reinforcement may not have ad- equate low-frequency sensitivity to pick up the low- frequency noise of machinery in a factory. 3.3.3 Audio Outputs Three-terminal removable barrier block connectors are provided for audio output (Figure 3.15). Both a main and bus output are provided for each of the two mixer channels. They are balanced and can drive 1200 ohms or more to +26 dBu or 600 ohms to +20 dBu. Each bus output can drive any number of inputs within this impedance range. The main audio outputs are provided for connection with other audio equipment such as power amplifi- ers. They can also be stacked with the outputs of other mixer/multiplexers to increase the number of mixer inputs. For example, two 6x2 MPX-6s can be stacked to create a 12x2 mixer. This is described in Section 3.3.4. The bus outputs are turned on or off by relays and function like the aux send outputs on a conventional mixing console. They are switched on or off by the IQ System. This special design allows many bus outputs to be connected to a common audio bus in a multiple-zone network (like a large airport paging Rev. 0 system). Because the bus outputs are controlled by the IQ System, they can be kept off until they are actually used, preventing too many of them being on at the same time and loading down a common audio bus network. The versatile bus outputs can be used for any audio system, small or large, where switchable outputs are desired, such as switchable recording outputs. Both main and bus outputs are wired the same way. Balanced output wiring is shown below. Notice that the shield is not connected to the output ground terminal if the load is connected to AC ground. This prevents unwanted ground loops. Un- balanced output wiring is shown next.

IQ Mixer / Multiplexer Hardware Installation 3.3.5 Paralleling Inputs When using more than one unit, the inputs may be wired in parallel to increase the number of outputs that a source can drive. This is shown in Figures 3.20-21. For example, the audio signal in Figure 21 which feeds Input 1 is available to the outputs of both units, creating a 6x4 mixer. Important: If the source is a microphone which re- quires phantom power (P) select it only at the first input. Switch all other parallel inputs to mic (M). Note: When mixer inputs are paralleled, the total input impedance will drop by 1¦N where N is the number of inputs to be connected. Depending on the signal source, this may place a limit on the number of possible outputs. 6 INPUTS SMX-6 PARALLELED INPUTS 12 INPUTS MPX-6 8OUTPUTS MAIN STACK OUT IN MPX-6 SMX-6 SMX-6 2OUTPUTS STACKED MPX-6 OUTPUTS Fig. 3.18 A 12x2 Mixer Using 2 Mixer/Multiplexers Fig. 3.20 A 6x8 Mixer Using 4 Mixer/Multiplexers To signal source First Unit AUDIO OUT2 MAIN STACK IN AUDIO STACK BUS + – + – + – + – Fig. 3.21 Paralleling the Inputs of Multiple Units Rev. 0 OUT1 MAIN IN BUS First Unit 3-pin output connector Connect ground ( ) from output to phone plug shield Second Unit Second Unit + – + – + – + – AUDIO IN2 -5 0 5 ADD FOR MIC 25 10-10-12 2115 AUDIO IN1 LM P -5 0 0 5 ADD FOR MIC 25 10-10+ -12 – 2115 LM P (–) No connection + – 2-conductor shielded cable Do NOT tie ground terminals of parallel inputs together 2-conductor shielded cable Phone (RCA) plug Connect shield to ground terminal of input ONLY AUDIO OUT2 STACK IN AUDIO BUS OUT1 MAIN STACK IN BUS AUDIO IN2 -5 0 5 ADD FOR MIC 25 10-10-12 2115 3.3.4 Stack Inputs The stack in jacks (Figure 3.15) enable the audio inputs to be increased by stacking 2, 3, or more mixer/multiplexers to create a 12x2, 18x2 or wider mixer. Use 2-conductor shielded cable to route the signal from the main output of one unit to the stack input (RCA phono jack) of the second unit. This is shown in Figure 3.19. The stack input routes the signal directly to the output of the second unit. Use the outputs of the last unit in the stack for connec- tion to amplifiers or other external audio equipment. Note: The level of each signal on the stacked output bus is controlled by the unit having the signal as an input. Stacking mixer/multiplexers can create an almost unlimited number of inputs. However, there will still only be two main and two auxiliary bus outputs for connection to other equipment. See Section 3.3.5 to find out how to increase the number of outputs.

For example, auxiliary cooling for an amplifier equipment rack can be controlled using the Aux port to control a solid state relay which in turn controls a cooling fan. This is shown below in Figure 3.23: AUX CONNECTOR GND 10 V The solid state relay shown (Crown part number C 7308-7) can be ordered from Crown. The Aux port uses a male 3-pin mini XLR connector which is located above the DB25 connector (Figure 2.1). Use a Switchcraft® TA3F cable connector or equivalent to make the connection. When the Aux port is turned on by the IQ System it provides 10 VDC across pins 3 (+) and 1 (ground).

The first is direct RS232/RS422 communication with the unit where the unit is its own interface and interface for any connected components. The sec- ond, called Crown Local Net, applies only to SMX-6 mixers. 4.1 A 1-Loop IQ Interface The serial port allows any of the mixer models to serve a an IQ interface between a host computer and a single Crown Bus loop. Note: While 250 IQ components of each type can be controlled on a single Crown Bus loop, it is recom- mended that no more than 20 units be connected to an AMB-5 or SMX-6. This is because of the tremen- dous timing demands on their microprocessors. More than 20 IQ components may cause timing problems. The MPX-6 has no such limitations. Note: While the mixers may be used as a system interface, they do not support IQ2 protocol as an interface. The only components that an IQ mixer may used as interface for are other mixers, MRX relay modules, and IQ-PIP-AP modules. With the built in serial port an IQ mixer can eliminate the need for an external IQ Interface (IQ-INT II) in a small system. The mixer connects directly to the host computer via the DB25 serial connector. Switches accessed through the side of the chassis are used to select the serial interface configuration, parity and baud rate. See Section 3.1 for specific wiring and switch instructions. 4.2 Crown Local Net Crown Local Net is available only for an SMX-6. It enables multiple SMX-6s to be interconnected via a Crown Local Net (CLN). This is a pseudo-RS422 communication loop designed for local communica- tion between IQ components apart from the Crown Bus. SMX-6s can use this option to communicate the total number of open mics in the system as well as their individual ducking priorities. In this way, one SMX-6 will know how many mics are being used by other SMX-6s and can take appropriate action to prevent feedback or implement priority switching (ducking) of mics. Note: Because RS232/422 and CLN use the same DB25 connector, they cannot be used at the same Page 20 IQ Mixer / Multiplexer Hardware Installation time. This means that SMX-6s will need to be con- nected to a Crown Bus via an external IQ interface for setup of a CLN. 4.2.1 Wiring the Crown Local Net A Crown Local Net is a serial loop (Figure 4.1). With two exceptions, a Crown Local Net loop is wired the same as standard RS422 wiring. Exception 1: The Crown Local Net does not use handshaking, there- fore pins 4 and 5 (RTS/CTS) are not used. Exception 2: When more than 2 components will be communi- CLN Interface (RS422) CLN Interface (RS422) CLN Interface (RS422) Fig. 4.1 A Crown Local Net RS422 Serial Loop cating on a Crown Local Net, two cables must be connected to each DB25 connector...one for incom- ing data and one for outgoing data. With two units on a Crown Local Net, only one cable is attached to the connector. Figure 4.2 shows the wiring for a 3-unit Crown Local Net. If more units are desired, simply add another unit and follow the same pattern for wiring. Note: Pin 7 should not be used as a ground if the units are already properly grounded. The wire used for RS422 communication is usually unsuitable for use as a ground. Important: The Crown Local Net must make a com- plete loop. If the last unit in a group is not connected to the first unit, the system will not function. Important: The Crown Local Net depends on proper IQ address assignments, even if the system will not be installed with a Crown Bus loop. Each unit in a Crown Local Net must have a different IQ address. See Section 3.2 for details. As more diverse IQ communications are needed, the Crown Local Net will be available to move infor- mation directly between IQ components without af- fecting the performance of a host computer.

IQ Mixer / Multiplexer Hardware Installation 6 Technical Information The IQ System was developed to provide a way to both monitor and control complete sound systems during operation. The system began with amplifier control using plug-in IQ-P.I.P. modules in each am- plifier and an IQ-INT to connect the system to a host computer. The next major advance was the MPX-6, the first intelligent mixer/multiplexer able to mix and route audio inputs under computer control. Now, the SMX-6 and AMB-5 sensing mixers offer advanced signal processing and have the capability of mixing audio signals automatically. 6.1 Audio 6.1.1 Input Section Each audio input signal first passes through a bal- anced filter designed to eliminate RF interference. The RF filters are a balanced network of chokes, ferrite beads and capacitors that attenuate both common-mode and differential-mode signals above 500 kHz. Optional input isolation transformers can also be added by the factory. The signal then enters the input switching circuit. This circuit can insert a 25-dB pad for line level signals or apply phantom power to the input termi- nals (44 volts through two 6810-ohm resistors). The signal is filtered again to eliminate lower-frequency RF energy such as interference from the AM broad- cast band. The signal then goes to the preamp stage. Each of the six input preamplifier stages is a bal- anced circuit providing from 13 to 46 dB of voltage gain. The preamp consists of a pair of low-noise transistors followed by a high performance op-amp. The transistors, in effect, convert the input voltage to a current while maintaining reasonably high input impedance. Their transconductance (output current divided by input voltage) depends on the setting of the gain control. The op-amp then converts the current back to a voltage to drive subsequent cir- cuits. 6.1.2 VCA Sections Each preamplifier output drives two VCAs which then drive the two current-summing mix buses. The stack inputs also feed into the mix buses. The VCA’s derive their control voltages from a multi- plexer circuit driven from the microprocessor. The microprocessor uses onboard algos or commands from a host computer to control the VCAs (depend- Rev. 0 ing upon the model). Levels can be set in 1¦2 dB increments from 25 dB gain to 100 dB attenuation (which is considered off). 6.1.3 Output Section The two mix buses are sent to the corresponding main output and auxiliary bus output stages. All output stages are active, balanced and can drive 1200 ohms to +26 dBu or 600 ohms to +20 dBu. The auxiliary bus output stages have internal relay con- tacts which can connect or disconnect the signal to the auxiliary bus output connector. These contacts are controlled by the host computer and thus allow programmed signal routing. Optional output isola- tion transformers can also be added by the factory. 6.1.4 Level Sense Circuits (AMB-5 and SMX-6 only) The output of each input preamp and each mix amp is monitored by a corresponding level detector. Each level detector tracks the peak level of the signal and releases with a time constant of about 85 ms. The eight levels are sent to a multiplexer and the A/D converter. 6.2 Control and Interface Section The host computer communicates with the unit mi- croprocessor either through an outboard IQ inter- face (like an IQ-INT) via the Crown Bus, or directly through the RS232/RS422 port. Each unit acts only on commands with an address matching its own. 6.2.1 Crown Bus Interface The serial loop (Crown Bus) connections on the unit are made with an opto-isolated 4-pin removable barrier block connector and a ground stud for the optional connection of shielded wire. To prevent ground loops, only the input cable’s shield should be connected. These connections conform to IQ System standards, which allow the host computer to control numerous IQ components with the same computer program. 6.2.2 RS232/RS422 Interface Depending on selected options, the DB25 connector can be used to communicate directly with the host computer for setup or control of a Crown Bus loop, or (SMX-6 only) for connection to an RS422 Crown Local Net. A switch selects either RS232 or RS422 operation. Page 23 6.2.3 D/A Converter To set channel gain levels, a digital-to-analog con- verter continuously converts all gain settings to control voltages. An analog demultiplexer sends the appropriate control voltages to each of the twelve VCAs. 6.2.4 Log Amp and A/D Converter The A/D converter scans through an eight-channel multiplexer to read the input and output signal lev- els. When a channel is selected, the signal is sent through a logarithmic amplifier for increased dy- namic range. This analog voltage is then converted to a binary number that the microprocessor can read. The processor can then mathematically in- crease detector time constants, perform averaging or other response functions. Page 24 IQ Mixer / Multiplexer Hardware Installation 6.2.5 Auxiliary Port Auxiliary devices such as supplemental cooling fans can be remotely controlled via the AUX output on the unit. When the auxiliary control feature is turned on by the host computer, 10 VDC is supplied across pin 3 and pin 1 (ground) of the male 3-pin AUX connector. This port can control solid state relays, and since it has a current-limit resistor (16 mA max.), it can directly drive an LED or opto- coupler. The AUX input function is used by applying a 5-30 VDC signal to pin 2 (with pin 1 as ground). A high or low signal here will be communicated to the host computer. A logic low can be less than 0 volts (negative); the signal is internally clamped for cir- cuit protection. Rev. 0
