BASS PEAK LEVEL
With Dolby Digital and DTS , not only the LFE (Low Frequency
Effects), but also the bass of all channels can be heard from the
Subwoofer or Large-speakers. This procedure prevents these
speakers from becoming too loud and creating an unbalanced sound.
Since the sound is output at a loud volume, perform this operation
carefully.
Note:
• If your system does not include a subwoofer, this setting will set
the bass peak level for your front speakers.
