Connecting an external power amplifier
(RX-V781 only)
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.
a SUR. BACK jacks
Output surround back channel sounds. When using only one external amplifier for the surround back
channel, connect it to the SINGLE jack (L side).
b SURROUND jacks
Output surround channel sounds.
c CENTER jack
Outputs center channel sounds.
d FRONT jacks
Output front channel sounds.
e SUBWOOFER1-2 jacks
For connecting a subwoofer with built-in amplifier. When 2 subwoofers are connected, the same sound
is output from them.
Connecting a device compatible with the trigger
function
The trigger function can control an external device in conjunction with operating the unit (such
as powering on/off and input selection). If you have a Yamaha subwoofer that supports a
system connection or a device with a trigger input jack, you can use the trigger function by
connecting the external device to the TRIGGER OUT jack with a monaural mini-jack cable.
X
You can configure the trigger function settings in “Trigger Output” (p.124) in the “Setup” menu.
Caution
• To prevent the generation of loud noises or abnormal sounds, make sure the followings before
making connections.
– Remove 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 an external amplifier that does not have the volume control bypass, do not connect
other devices (except the unit) to the amplifier.
