HT-R410
ADJUSTMENT AND CONFIRMATION PROCEDURES 1
Idling current adjustment
Before Idling adjustment, turn the trimming resistors R6040,R6041,R6042,R6043 and R6044 to counter clockwise.
Connect the DC voltmeter to sockets P6080,P6081,P6082,P6083 and P6084.
After turn POWER to ON, adjust the trimming resistors R6040, R6041 and R6042 so that the reading of
voltmeter becomes 2.5 mV. (Front and Center channels)
Adjust the trimming resistors R6043 and R6044 so that the reading of
After adjustment, attach the top cover.
voltmeter becomes 1.5 mV. (Surround channels)
Confirm the voltage of points above after about five minutes.
Front and center channels
When less than 7.0 mV, readjust the resistors above so that the voltage becomes 7.0 mV.
When 7.0 mV to 9.0 mV, you are not necessary to adjust.
When more than 9.0 mV, readjust the resistors above so that the voltage becomes 9.0 mV.
Surround channels
When less than 4.0 mV, readjust the resistors above so that the voltage becomes 4.0 mV.
When 4.0 mV to 6.0 mV, you are not necessary to adjust.
When more than 6.0 mV, readjust the resistors above so that the voltage becomes 6.0 mV.
Note: No load and No signal
Confirmation of protection circuit
1. Confirmation of operation of speaker relay
Confirm that the speaker relays turn ON approximate. 5 seconds after the power switch is turned ON.
Confirm that the speaker relays turn OFF immediately after the power switch is turned OFF.
2. Confirmation of DC detection circuit
Press and hold down CD button, then press STANDBY/ON button to display "TEST-" on FL tube.
Then press DVD button to display "TEST-1-00".
Apply DC 1.5 to 3V to Multi-channel INPUT terminal with no load.
Confirm that the speaker relay turns OFF.
Apply DC -1.5 to -3V to DVD INPUT terminal with no load.
Confirm that the speaker relay turns OFF.
Caution: Don't apply DC voltage more than 1 sec..
