4.4.2. Balance Loudspeaker Channel
Positive balance settings reduce the left channel without
affecting the right channel; negative settings reduce the
right channel leaving the left channel unaffected. In lin-
ear mode, a step by 1 LSB decreases or increases the
balance by about 0.8% (exact figure: 100/127). In loga-
rithmic mode, a step by 1 LSB decreases or increases
the balance by 1 dB.

4.4.3. Bass Loudspeaker Channel
With positive bass settings, internal overflow may occur
even with overall volume less than 0 dB. This will lead to
a clipped output signal. Therefore, it is not recom-
mended to set bass to a value that, in conjunction with
volume, would result in an overall positive gain.
