Using the Integrated Amplifier as a Power Amplifier

Combined with a preamplifier of your choice, the integrated amplifier can be used as a power amplifier (Main mode). When it is selected, the MAIN IN LED lights. See “Connecting Your Speakers” for connection information

(page 13). This is an example of connection using the preamplifier P-3000R.

Important:

Always turn the integrated amplifier off before connecting the MAIN IN jacks.

Before setting the integrated amplifier to Main mode, make sure that no component such as a CD player is connected to the MAIN IN jacks, as a direct connection may cause a massive blast sound and damage the integrated amplifier or your speakers.

This mode can be used with the following limitations:

The volume level can’t be adjusted.

Only SPEAKERS and SETUP can be used.

Only the MAIN IN and SPEAKERS terminals can be used.

The Auto Standby function is not available (page 38).

To use this mode, you need to change the “ROUTE” setting (page 39).
