⢠Perform adjustments in the HI-VOLTAGE mode. 1 Adjustment point Semi-fixed resistors VR101, VR201, VR301, VR401, VR501, VR502 of amplifier board 2 Precautions on adjustments 1. Set the RCA input terminal to open. 2. Apply a voltage of 14.4V between the +12V terminal, REMOTE terminal, and GND terminal. 3. Rotate the above semi-fixed resistors completely in the counterclockwise direction while observing the component side. 4. Check that the voltage at the adjustment point becomes 0 mV in step 2. 5. Fine adjustments may be required according to the characteristics of the MOS-FET used. ⢠When adjusting the idling current Rotating the semi-fixed resistor in the clockwise direction: Increases the idling current Rotating the semi-fixed resistor in the counterclockwise direction: Decreases the idling current * Take note that rotating excessively in the clockwise direction will increase the idling current suddenly. 3 Approximate adjustment values Adjust as follows so that the following voltages become 1.2 to 0.3 mV around 0.7 mV . FL channel : Voltage between TP7 and TP6: Use VR101 of the amplifier board FR channel : Voltage between TP7 and TP5: Use VR201 of the amplifier board RL channel : Voltage between TP7 and TP4: Use VR301 of the amplifier board RR channel : Voltage between TP7 and TP3: Use VR401 of the amplifier board SUBWOOFER Channels : First, adjust so that the voltage between TP1 and TP2 becomes 1.2 to 0.3 mV around 0.7 mV using VR501 of the amplifier board. Next, adjust so that the voltage between TP1 and TP2 becomes 2.4 to 0.6 mV around 1.4 mV using VR502 of the amplifier board.â Connection :
