Connecting an external amplifier

The same channel signals are output from the jacks of the PRE
OUT terminals as from their corresponding SPEAKERS terminals.
When connecting an external power amplifier (pre-main amplifier)
to enhance speaker output, connect the input terminals of the power
amplifier to the PRE OUT terminals of this unit.
NOTES
• When a component is connected to the PRE OUT terminals, do
not connect speakers to the SPEAKERS terminals corresponding
SW
to those PRE OUT terminals.
• When an external amplifier equipped with a volume adjustment
function is connected, a sufficient volume level may not be achieved.
Use of the following components is recommended.
– An amplifier with no volume adjustment function.
– An integrated amplifier equipped with a function that bypasses
volume circuitry, such as the Yamaha A-S2000 with MAIN IN
input.
