CxEQBP



0: perform EQ on channel X - normal operation



1: bypass EQ on channel X

Tone control (bass/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

controlled to be in binary operation mode.

Also, there is the capability to map each channel independently onto any of the two limiters

available within the STA326 or even not map it to any limiter at all (default mode).

Each PWM output channel can receive data from any channel output of the volume block.

Which channel a particular PWM output receives is dependent upon that channel’s CxOM
