Connections
■ Connecting an external amplifier
This unit has more than enough power for any home use. However, if you want to add more power to the speaker output
or if you want to use another amplifier, connect an external amplifier to the PRE OUT jacks. Each PRE OUT jack outputs
the same channel signals as the corresponding SPEAKERS terminals.
• When you make connections to the PRE OUT jacks, do not make connections to the SPEAKERS terminals.
• The signals output at the FRONT PRE OUT jacks are affected by the TONE CONTROL settings (see page 52).
• Adjust the volume level of the subwoofer with the control on the subwoofer (see page 52).
• Some signals may not be output at the SUBWOOFER PRE OUT jacks depending on the settings for “SPEAKER SET” (see page 85).
1 FRONT PRE OUT jacks
Front channel output jacks.
2 SURROUND PRE OUT jacks
Surround channel output jacks.
3 SUR.BACK PRE OUT jacks
Surround back channel output jacks. When you only
connect one external amplifier for the surround back
channel, connect it to the SINGLE jack.
• When “BI-AMP” is set to “ON”, this unit outputs the front
channel audio signals at the SUR.BACK PRE OUT jacks.
• The audio signals output at the SUR.BACK PRE OUT jacks
differ depending on the “EXTRA SP ASSIGN” setting (see
pages 33 and 85).
4 SUBWOOFER PRE OUT jacks
Connect one or two subwoofers with a built-in amplifier.
The signal output at the SUBWOOFER PRE OUT 2 is the same
as the one output at the SUBWOOFER PRE OUT 1 jack.
5 CENTER PRE OUT jack
Center channel output jack.
