Service bulletin # 9606 August 1996
Warranty labor rate: MINOR repair
To: All harman/kardon Service Centers
Models: AVR-10 /AVI-100
Subject: Rear channel volume level
_____________________________________________________________________________________
While playing certain Dolby Pro Logic program material with low sensitivity rear channel loudspeakers, the
perceived volume level from the rear loudspeakers may be lower than the volume level from the front speakers.
To increase the volume level from the rear channel with approximately 5 dB, perform the following
modification:
1) Locate the Surround Sound PCB, (PCB10) close to the rear of the product. PCB-10 is mounted vertically.
Locate on PCB-10 IC304. IC304 is the Surround Sound signal amplifier.
2) Pin 6 of IC304 is connected to feedback resistor R353 (1K8). R353 is mounted vertically, located closely  to
pin 5 of IC304. The marking “R353” on the PCB is not directly next to the resistor.
3) Tack solder on the foil side of R353 a 2K2 resistor. This 2K2 resistor is now in parallel with the existing 1K8
resistor.
Note: After the modification is completed, the combination of sensitive rear channel loudspeakers with a high
setting of the rear channel volume may result in audible noise from the rear loudspeakers.
