ADJUSTMENT AND CONFIRMATION PROCEDURES
1.Idling current adjustment
Before Idling adjustment, turn the trimming resistors R6040 to R6045 counter-clockwise fully.
Connect the DC voltmeter to sockets P6080 to P6084.
After turn POWER to ON, adjust the trimming resistors R6040, R6041 and R6042 so that the reading of
voltmeter becomes 1.25mV. (Front and center channels)
Adjust the trimming resistors R6043, and R6044 so that the reading of
voltmeter becomes 0.75 mV. (Surround and surround back channels)
After adjustment, attach the top cover.
Confirm the voltage of points above after about five minutes.
Front and center channels
When less than 5.0 mV, readjust the resistors above so that the voltage becomes 5.0 mV.
When 5.0 mV to 6.0 mV, it is not necessary to adjust.
When more than 6.0 mV, readjust the resistors above so that the voltage becomes 6.0 mV.
Surround and surround back channels
When less than 3.5 mV, readjust the resistors above so that the voltage becomes 3.5 mV.
When 3.5 mV to 4.5 mV, it is not necessary to adjust.
When more than 4.5 mV, readjust the resistors above so that the voltage becomes 4.5 mV.
Note: No load and No signal
