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.

CxEQBP:

●

0: perform EQ on channel X (normal operation)

●

1: bypass EQ on channel X

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:

●

0: perform tone control on channel x – (default operation)

●

1: bypass tone control on channel x

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.
