EQ control can be bypassed on a per channel basis. If EQ control is bypassed on a given
channel the prescale and all 9 filters (high-pass, biquads, de-emphasis, bass management
cross-over, bass, treble in any combination) are bypassed for that channel.

Tone control (bass and treble) can be bypassed on a per channel basis. If tone control is
bypassed on a given channel the two filters that tone control utilizes are bypassed.
CxTCB:
●
●
Each channel can be configured to output either the patented DDX PWM data or standard
binary PWM encoded data. By setting the CxBO bit to ‘1’, each channel can be individually
set to binary operation mode.
