LS_BASS_GAIN

Loudspeakers Bass Gain Register

Note:

With positive bass/treble settings, internal clipping may occur even with an overall volume of less

than 0 dB. This will lead to a clipped output signal. Therefore, it is not recommended to set bass/

treble bands to a value that, in conjunction with volume, would result in an overall positive gain.

LS_TREBLE_GAIN

Loudspeakers Treble Gain Register

With positive bass/treble settings, internal clipping may occur even with an overall volume of less

than 0 dB. This will lead to a clipped output signal. Therefore, it is not recommended to set bass/

treble bands to a value that, in conjunction with volume, would result in an overall positive gain.
