Adding Amplifiers in the BTL Mode

Adding amplifiers while in the BTL mode makes possible the creation of a sound system with total output greater than 120 watts.

Only use this switch when the power is off. Set the NORMALIBTL switch t o the BTL side. Connect the speakers as shown in the diagram.

Sound is produced from the outside speaker terminals when using the AVC20 in the BTL mode. (The rear "+" speaker terminals become BTL 'I - " speaker terminals.)

Connection (A)

@To use the AVC20 on the two front channels and use the two rear channels with other amplifiers, remove the U-shapedshort pins as shown in the diagram.

(In order not to lose the pins, use cellophane adhesive tape or the like to fix them to the rear panel.)

@Connect the REAR- PRE OUT terminals to the AUX IN terminals of the added stereo amplifier using pin plug cables.

@When this is done, the AVC20 volume control can be operated, but the volume of the other amplifier must be increased to match that of the AVC20.
