Model: AVR325, AVR525, AVR430, AVR630 Subject: Rewiring Bias/Fan cables In the event you receive an AVR325, AVR525, AVR430 or AVR630 with the complaint: “the unit intermittently goes in standby or the fan runs constantly” perform the following modification. Please note other component or connection failures can cause the unit to go in to standby.
Page 26 AVR525 4) Unplug each the cable on the Bias PCB, desolder the female plugs, cut the connectors off each wire, strip the insulation 1/8” on each end and solder directly to the PCB assembly in each location. 5) For locations N801, N802, N803, N804 on the Main PCB, set the unit on its side and remove the bottom grille.
Page 27 AVR525 7) Replace the DSP and Processor boards 8) Recheck all bias voltages, following the instructions below: MAIN AMP IDLE CURRENT ADJUSTMENT PROCEDURE (Set variable resistors for MAIN/SURROUND Board) Specialized equipment/parts needed: Variable AC transformer (“Variac” type) to adjust and monitor AC line voltage.

Page 135 AVR525 harman/kardon 8-channel analog multiplexer / demultiplexer BU4051BC / BU4051BCF / BU4051BCFV The BU4051BC, BU4051BCF and BU4051BCFV are analog multiplexers / demultiplexers which use three-input digi- tal signals for control via an 8-channel analog switch. These products feature high on / off output voltage ratio and low crosstalk between analog switches.
Page 136 AVR525 harman/kardon Triple 2-channel analog multiplexer / demultiplexer BU4053BC / BU4053BCF / BU4053BCFV The BU4053BC, BU4053BCF, and BU4053BCFV are multiplexers / demultiplexers capable of selecting and combin- ing analog signals and digital signals in a 2 ch × 3 configuration. Inhibit signals and control signals are used to turn on the switch corresponding to each of the channels.
