ADJUSTMENT OF IDLING CURRENT
Applied to the following model.
(Model) TX-SR333/HT-RC630
a. Pre-adjustment
Set the following registers to minimum position before POWER ON.
Set the voltages at the following terminals to the following voltage by adjusting the following registers, under the condition of
no input and no load, immediately after POWER ON.
Channel L/C/R
SL/SR
Terminals
Registers
Voltage 2.5mV
---
About SL/SR Channel, adjustment is unnecessary.
If the measured value of SL/SR Channel are under 1mV or over 21mV, turn off the power of the AVR and rework the AVR.
b. Aging
Heat run during the following time.
Time
c. Final adjustment
Re-adjust by the following procedure after heat running for the above mentioned time.
L/C/R
Below 9mV 9mV
Between
Do not adjust.
Over 11mV 11mV
Equip series 1/4W 100-ohm resisters near the terminal respectively in each pole of the jig used for the above mentioned terminals.
