PREPARATIONS > How to place speakers (speaker systems) Connecting an external power amplifier When connecting an external power amplifier (pre-main amplifier) to enhance speaker output, connect the input jacks of the power amplifier to the PRE OUT jacks of the unit. The same channel signals are output from the PRE OUT jacks as from their corresponding SPEAKERS terminals. NOTICE To prevent the generation of loud noises or abnormal sounds, make sure the followings before making connections. ( Unplug the power cable of the unit and turn off the external power amplifier before connecting them. ( When using the PRE OUT jacks, do not connect speakers to the corresponding SPEAKERS terminals. ( When using a pre-main amplifier that does not have the volume control bypass, turn up the volume of the pre-main amplifier enough and fix it. In this case, do not connect other devices (except the unit) to the pre-main amplifier.
