Register description: New Map STA382BWS
EQ control can be bypassed on a per-channel basis for channels 1 and 2. If EQ control is bypassed on a given channel, the prescale and all filters (biquads, bass, treble in any combination) are bypassed for that channel.

Each channel contains an individual channel volume bypass. If a particular channel has volume bypassed via the CxVBP = 1 register, then only the channel volume setting for that particular channel affects the volume setting, the master volume setting will not affect that channel.
