Operating Your Lifestyle® 40 Music System

Equalizing the volume levels of external sources

The SIGNAL LEVELS selection in the MENU options allows you to adjust and equalize the volume gain levels received from externally connected sources (VIDEO 1, VIDEO 2, AUX, TAPE). For example, you can adjust the gain level of an external source so that volume level 50 on this source sounds as loud as level 50 from a built-in source.

1.Using the MENU button, select SIGNAL LEVELS.

2.Press VIDEO 1, VIDEO 2, TAPE or AUX and you are shown a gain adjustment display (Figure 34). After listening to the built-in sources (FM, AM, CD) at your preferred volume level, use the arrow keys to adjust the signal level settings (GAIN) of the connected sources until you get the same volumes. The adjustment range is from –15 to +15.
