Connect a single (RCA) cable from the signal generator to the line in jack on the UUT. GAIN control should be full counterclockwise. Off/Auto/On switch should be OFF.EQ switch should be on Normal.Turn Crossover knob to full CW (150)Position of phase switch is irrelevant.2. Turn on generator, adjust to 200mV, 30 Hz.3. Plug in UUT; red LED should be ON. Turn GAIN control full clockwise. 4. Bass response should be substantial, and woofer at near maximum excursion.5. Turn off generator, turn VOLUME control fully counterclockwise, disconnect RCA cable.Sweep Function1. Follow steps 1-4 above, using a sweep generator as a signal source.2. Sweep generator from 20Hz to 300Hz. Listen to the cabinet and drivers for any rattles, clicks,buzzes or any other noises. If any unusual noises are heard, remove driver and test.Driver Function1. Remove driver from cabinet; detach + and - wire clips.2. Check DC resistance of driver; it should be 8.1 ohms 10%.3. Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrat-ed amplifier fed by a signal generator and adjust so that speaker level output is 5.0V.4. Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusualnoises.SIGNALGENERATORAC VOLTMETER (6V)HTPS-400UNDER TEST0036700368HTPS-400 ADJUST BIAS PROCEDURE(Mandatory when any output MOSFET transistors Q305,310,320,321,306,307,311,312 are replaced)1. Amplifier should be unplugged and OFF.2. Remove Amp assembly from cabinet.3. Identify the Linear board assembly (PCB with the output transistors)4. Adjust RP301 and RP302 fully Counter Clockwise. See diagram below.5. Apply 120 VAC power to unit.6. Verify LED is ON.7. Connect voltmeter set to DC millivolt range to twin pins on terminal J303, on Linear board.8. Verify initial voltage is less then 0.1 mV.9. Adjust RP301 Clockwise until voltmeter reads 0.3 mV + the initial current from step #8.10. Adjust RP302 Clockwise until voltmeter now reads 0.6 mV + the initial current from step #8.11. Turn amplifier OFF. Disconnect AC power to unit.12. Remove voltmeter from terminal J303.13. Replace amp assembly back into cabinet.15HTPS-400 SUBWOOFER16Electrical Parts ListPartReferenceQuantityDescriptionNo.DesignatorPCB, INPUT FEATURESemiconductorsUA0003U2,U3,U43OPAMP, QUAD 14PIN DIL
