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.
