7.23.4
Limiter Zero Cross Disable
Configures an override of the digital zero cross setting.
7.24
Limiter Control 2, Release Rate (Address 28h)
7.24.1
Peak Detect and Limiter
Configures the peak detect and limiter circuitry.
7.24.2
Peak Signal Limit All Channels
Sets how channels are attenuated when the limiter is enabled.
7.24.3
Limiter Release Rate
Sets the rate at which the limiter releases the digital attenuation from levels below the CUSH[2:0] thresh-
old (“Limiter Cushion Threshold” on page 53) and returns the analog output level to the MSTxVOL[7:0]
Note:
The limiter release rate is user-selectable but is also a function of the sampling frequency, Fs,

Limiter Zero Cross Disable
0
OFF; Limiter Attack Rate is dictated by the DIGZC (“Digital Zero Cross” on page 45) setting

Apply the necessary attenuation on a specific channel only when the signal amplitude on that specific chan-
nel rises above LMAX.
Remove attenuation on a specific channel only when the signal amplitude on that specific channel falls below
CUSH.
1
Apply the necessary attenuation on BOTH channels when the signal amplitude on any ONE channel rises
above LMAX.
Remove attenuation on BOTH channels only when the signal amplitude on BOTH channels fall below CUSH.
