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).
