TIP# HKTT2004-03
Isolating audio problems in an AVR receiver
Using 6/8 Direct In
The following charts are used to help the tech quickly isolate
audio problems in an AVR receiver. Use the following
procedures to help find what is working, then to quickly locate
the problem area.
Equipment needed:
91 set of (RCA) Y adaptors.
9Function/signal generator.
9Oscilloscope.
Models covered:
AVR210 AVR310
AVR220 AVR320
AVR520 AVR225
AVR125 AVR525
AVR130 AVR230
AVR330 AVR430
AVR630
Procedure:
1) Do a factory reset of the receiver. (This will eliminate any common micro processor
problems.) Reset List can be found near the last page or check the service
website; www.harmanservice.com for the latest info.
2) Print the block diagram from the service manual.
3) With no inputs or speakers attached to the AVR turn on the receiver and turn the
volume all the way down.
4) Turn unit off.
5) Hook up an oscillator to the 6/8 Direct in jacks using the Y adaptors. Adjust the
oscillator to about 0db (.775Volts RMS).
6) Hook up an oscilloscope to monitor the line out jacks. Or, if there are no line out
(preamp out) jacks monitor the input to the power amps or the speaker outs.
(AVR125, 225, 130 do not have preamp out jacks)
7) Turn the AVR on. Select 6 or 8 direct in, depending on the receiver.
8) Slowly turn the volume control up until you can easily measure the voltage at the line
out jacks. ( -40 to -25db )

Isolating audio problems in an AVR receiver
Using 6/8 Direct In
9) At this point you will be able to check and assure all output levels are the same.
10) IF THE OUTPUT LEVELS ARE NOT THE SAME STOP! Go no further. At this point
you will need to use the charts to see where you are losing your signal. The chart
shows the analog signal flow from the input jacks to the output jacks.
11) If the output levels are the same check the power out stage at the speaker out jacks.
12) If you find the levels at the speaker out jacks are OK, your problem will be in the DSP
part of the receiver.
Congratulations! You have now eliminated 90% of the electronics in the AVR and
confirmed that the problem is in the DSP section.

Quick Guide to h/k and JBL Microprocessor resets
In the rare case where the unit’s operation or the displays seem abnormal, the cause may involve the erratic operation of the
system’s memory or microprocessor.
NOTE: Resetting the processor will erase any configuration settings you or the customer have made for the product, e.g. speakers,
output levels, surround modes, digital input assignments as well as the tuner presets. After a reset the unit will be returned to the
factory presets, and any special settings for these items must be reentered.
