■ 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.
• When you make connections to the PRE OUT jacks, do not make any connections to the SPEAKERS terminals.
• Each PRE OUT jack outputs the same channel signals as the corresponding SPEAKERS terminals.
• Adjust the volume level of the subwoofer with the control on the subwoofer unit.
• Some signals may not be output at the SUBWOOFER PRE OUT jack depending on the settings for “SPEAKER SET” (see page 80).
• You can use the automatic setup feature even if you use an external amplifier (see page 37).
