10.3.40 B
This register is used to select from a few sample bass boost settings to modify the frequency characteristics of the Main
channel (shelving filter). Bits B3 to B0 apply to the left channel, bits B7 to B4 apply to the right channel. This function
must be used with care in order to avoid clipping distortion at high volume settings.
More sophisticated control of the bass boost filter can be exercised in the expert mode (see Section 10.5). The user then
has full control over this second-order filter and can, within limits, realize bass equalizers with arbitrary centre
frequencies, Q factors and boost/cut settings.

Note
1. The default setting at power-up is 0000 0000.
