function is affected, similar to attenuation changes, by the soft and zero cross bits (SZCMode[1:0]). See

“Volume and Muting Control” on page 36 for more information.

9.15.6 Sub Channel Mute (MuteSub)

Default = 0

Function:

The sub channel’s power PWM, logic-level PWM, and auxiliary serial data outputs will enter a mute state

when enabled. The muting function is affected, similar to attenuation changes, by the soft and zero cross

bits (SZCMode[1:0]). See “Volume and Muting Control” on page 36 for more information.

9.16 Limiter Configuration 1 (Address 5Ch)

9.16.1 Maximum Threshold (Max[2:0])

Default = 000

Function:

Sets the maximum level, below full scale, at which to limit and attenuate the output signal at the limiter

attack rate.

9.16.2 Minimum Threshold (Min[2:0])

Default = 000

Function:

Sets a minimum level below full scale at which the limiter will begin to release its applied attenuation.

MuteChX Setting
