Connecting an external power amplifier
When connecting an external power 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
FRONT jacks
Output front channel sounds.
b
SURROUND jacks
Output surround channel sounds.
c
SUR. BACK jacks
Output surround back channel sounds. When using only one surround back speaker, connect the
external amplifier to the SINGLE jack (L side).
d
CENTER jack
Outputs center channel sounds.
(Example)
Connecting front speakers via an external power amplifier
About external power amplifiers
We recommend using power amplifiers that meet the following conditions.
• With unbalanced inputs
• With volume control bypass (or without volume control circuit)
• Output power: 100 W or more (6 to 8 Ω)
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 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.
