L8400P L series OPERATION
Power
Move the Master Power switch ¢ to the �On� position to use the L8400P subwoofer. If you will be away from home for an extended period of time, or if the subwoofer will not be used, switch the Master Power switch ¢ to the �Off� position.

Level Control
The subwoofer Level Control � adjusts the volume of the subwoofer relative to the rest of the system. Proper level adjustment depends on several variables such as room size, subwoofer placement, type of main speakers and position. Adjust the subwoofer level so that the volume of the bass information is pleasing to you.

Crossover Adjustments
The Crossover Frequency Control ¶ determines the highest frequency at which the subwoofer reproduces sounds. If your main speakers can comfortably reproduce some low-frequency sounds, set this control to a lower frequency setting, between 50Hz and 100Hz. This will concentrate the subwoofer�s efforts on the ultradeep bass sounds required by today�s films and music. If you are using smaller bookshelf speakers that do not extend to the lower bass frequencies, set the low-pass crossover control to a higher setting, between 120Hz and 150Hz. This control is not used when the LFE switch � is in the �LFE� position.
