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.
1
F.PRESENCE jacks (RX-A3020 only)
Output front presence channel audio signals or Zone2 audio signals depending on the “Power
Amp Assign” setting (p.114).
2
R.PRESENCE jacks (RX-A3020 only)
Output rear presence channel audio signals or Zone3 audio signals depending on the “Power
Amp Assign” setting (p.114).
3
FRONT jacks
Output front channel sounds.
4
SURROUND jacks
Output surround channel sounds.
5
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).
6
CENTER jack
Outputs center channel sounds.

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: about 100 W (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.
