Bass Management Configuration 2

Configuration 2 assumes that the left and right speakers, are full range while the center and

surround speakers are smaller speakers. Also, all bass data is redirected to the left and right

speakers.

This configuration include output level adjustment that allows 12 dB attenuation for the 3 smaller

speakers (C, Ls, Rs). When the level adjustment will be disabled the decoder boosts by 12 dB the

full range speakers (Left, Right).
