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. Notes • 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 87).

When you only connect one external amplifier for the surround back channel, connect it to the SINGLE jack. Notes • 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 87). 4 SUBWOOFER PRE OUT jacks Connect one or two subwoofers with a built-in amplifier. Note The signal output at the SUBWOOFER PRE OUT 2 jack is the same as the one output at the SUBWOOFER PRE OUT 1 jack. 5 CENTER PRE OUT jack Center channel output jack. 24 En
