Adjustment method
<Adjustment method>
1. Prior to turning the power ON, fully turn the adjusting resistor (VR787(Lch),VR788(Rch)) counterclockwise
direction and connect the DC voltmeter to the measuring terminal(B2204-B2205(Lch) , B2213-2214(Rch)).
2. Set the surround mode OFF.
3. Adjust the resistor so that the measured value becomes 2mV immediately after turning the power ON.
4. When the idling current has been stable (about 30 minutes after the power is turned ON),
confirm that the measured value falls within 1.0mV `10mV(2.3mV).

Adjustment volume VR787(Lch) , VR788(Rch)
Attention
This adjustment does not obtain a correct adjustment value immediately after the amplifier is
used (state that an internal temperature has risen).
Please adjust immediately after using the amplifier after turning off the power supply of the
amplifier and falling an internal temperature.
* It is not abnormal though the idling current might not become 0mA even if it is finished to turn variable
resistance (VR787,VR788) in the direction of counterclockwise.
