INSTALLATION 4B. input Connections Two conductor shielded low-impedance cable is recom mended for input lines to the amplifier input. Pin 2 of the XLR-type connector is high (+), pin 3 is low ( - ), and pin 1 is ground. The 14-inch jack may be used as a low impedance input. Tip is high (+), ring is low (-), and the sleeve is ground. See Figure 3. High impedance lines may be connected to the amplifier inputs with a single-conductor low capacitance sheilded cable of 30 feet or less in length. A two conductor 14-inch plug will automatically unbalance the input. To help avoid hum or buzz in the output, be certain that all input cables are physically separated from power wiring or power transformers. 4A. Operating Cautions a. Do not operate the amplifier in a completely closed, unventilated housing. b. Do not connect the outputs of the channels in parallel. C. Do not connect the output terminals to a battery, power supply, or the power mains. Damage caused by such hookup is not covered by the warranty. d. Be careful when making connections, selecting signal sources and controlling the output level. e. Do not ite the input signal ground to the ground lead of an output. Ground-loop-induced oscillations may Occur. Ensure that the main ac power is within 10% of selected voltage and frequency. Failure to operate the unit within these limits voids the warranty. g. Use only the proper size mains fuse for the selected ac voltage. h. Do not connect either side of the loudspeaker cable to ground when operating the unit in bridged mode. The bridged mode is balanced to ground. i. Make certain that test equipment is not ground referenced when testing the unit in the bridged mode. Tampering with the circuit or repair by unauthorized personnel will void the warranty of the unit. 4C. Output Connections Binding posts are provided for speaker terminations, the red post is high (+) and the black post is low(-). The preferred connector is a high quality dual banana plug. See Figure 4 for typical output configurations. Before making output connections, the input attenuators should be turned off (full counterclockwise), doing so will eliminate any chance of loud blasts or damage to the loudspeaker. Power loss in the speaker wire. The impedance of the speaker connecting wire would ideally be zero, so all of the amplifier output power would be delivered to the speaker load. However, the impedance of the speaker wire can become a significant percentage of the speaker impedance. Thus, part of the amplifier power is "lost'' in the wire (in the form of heat) and the power delivered to the speaker system six EX 7300 STEREO POWER AMPLIFIER Operation AWG Size 10 to either of the black binding posts. Switch power on and slowly increase amplifier channel 1 level control until the desired output power is obtained. If the clip LED indicators come on, reduce the power amp level control or the source signal level. 120 12 .

No user serviceable parts inside. Hazardous voltage and currents may be encountered within the chassis. To avoid electric shock, do not perform any servicing unless you are qualified to do so. is correspondingly reduced. Wire impedance is higher when using long wire runs and small wire sizes. Table 1 shows the two-wire cable (copper) lengths permissable for a number of wire sizes and speaker impedances, to avoid a loss of more than 0.5 dB. For a loss of 1 dB (basically imperceptible) lengths may be doubled.; For a 2-dB loss, the lengths would be multiplied by 4.4. In general, note that the higher load impedances allow much longer smaller-gauge wiring to be used: 4D. Grounding The chassis of the unit should be grounded. Connecting the. chassis grounds of additional audio equipment to the chassis ground of the amplifier may help reduce noise and hum. 4E. Ventilation In order to offset the heat generated by the power amplifier, it is necessary to provide ample ventilation around the unit. Avoid blocking or impeding the vent slots of the chassis. Locate the unit where it is free from direct sunlight, humidity, dust or vibration to help prevent problems which might be caused by the environment. 5D. Alternate Primary Voltage The amplifier can be powered with line voltages other than 120 volts by altering the primary wiring of the power transformer. Table Il lists the primary wire color, the terminal block (TB), and the position of the TB the wire should be located in for operation at the desired voltage. To alter the transformer primary wiring configuration use the following procedure: 1. Disconnect the amplifier from the ac power source. 2 Remove the ten screws securing the top cover. There are three screws on each side; two screws on the rear along the bottom edge, and the two innermost screws inset into the top strip on the front panel. See Figure 5 for exact screw locations. Discharge each large capacitor carefully through a 150-ohm, 2-watt resistor for at least one minute. See Figure 6. 4. Locate the two voltage-selection terminal blocks mounted next to each other on the side of the chassis between the power transformer and the large capacitor. 5. The transformer has six primary leads. Disconnect the primary leads of the power transformer by pulling each wire firmly to disengage it from the terminal block. Note: The primary lead colors are black, brown, white, black/white, brown/white and white/black. Select the desired operating voltage on Table Il and reconnect the wires accordingly. Push each wire firmly into the block until it snaps into place. 7. Relocate the fan wires according to the wiring chart. 8. Install the correct line fuse (values in Table III). Plug the amplifier into a variac and sweep the mains voltage from zero to full operating voltage while monitor ing the amplifier's dc rail voltages. The dc rail voltage should be $78 V dc, 15% at the selected primary voltage 10. Reinstall the top cover with the ten screws. 5. OPERATION 5A. Dual/Stereo Mode: In the dual or stereo mode the channels may be operated independently. Before hook-up make sure that the mode switch is in the dual position and that the level controls are down (FCCW). Connect the inputs and outputs (See Figures 3 and 4). Turn the power amp on and slowly increase level until the desired output power is obtained. If either (clip) LED illuminates, reduce the output with the input attenuators or reduce the source signal leveli 5B. Bridge Mode: Input connection should be made into channel 1 only. Do not make any input connections into channel two. Move the mode switch to bridge mode and make sure both level controls are down (FCCW). Connect the speaker across the two red binding posts. Channel 1 red post is high (+). channel 2 red post is low (-). Do not make a connection 7300 STEREO POWER AMPLIFIER CO Permanent Connections * Factory Wiring (120 V) 100 V TB1 T82 TB1 TB2 T01 TB2 Ο (BLK) LINE CAP D (BLK) FUSE (BLK) PWA SW LINE CAP (BLK) 2 NEUTRAL (WH) BLK BLK/WH FAN (YL) (BLK) PWR SW AURLARLALALALALALAJO LALALALALALALALALAL 31BLK BLKWH IS FAN (YL) LALALALALALALALALALA LALALALALALALALALALO LLRALALALALALALA LALALALALALALALAL WH BAND BRNWHI (YL) FAN WH/BLK ||FAN (YL) 8 BRNWH 9 BAN G.

Protection If the amplifier goes into 'protect" mode it is probably for one of the following reasons: Very Low Impedance Load or Shorted Load. Disconnect the speaker lines from the power amplifier and allow the amplifier to cool. If the protect LEDs go out after a short period of time check the speakers or decrease the number of speakers attached to the outputs. 6. TROUBLESHOOTING a. Be systematic; check one thing at time; check the obvious. b. Verify that the input connections are properly made. See Figure 3, page 4. C. Verity that the output connections are properly made. See Figure 3, page 4. Check input and output cables for proper wiring. e. Check the signal source and the load.. Make sure the level controls are up. f. Check that the bridge mode switch is in the desired position. g. If there are no lights, check ac power switch and power fuse. Fuses that blow instantly on turn-on are a sign of internal distress, and you should refer the unit to a qualified service station. DC on the Output of the Amplifier. Disconnect the speaker lines from the power amplifier and allow the amplifier to cool. If the protect LEDs do not go out after a short period of time it is likely that a de voltage is on the output and that the amplifier will need servicing. n. 7.
