Limiter Threshold SZC Disable (Address 19h)
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 attack rate.
Bass, Treble and digital gain settings that boost the signal beyond the maximum threshold may trigger an
attack.
Cushion Threshold (CUSH[2:0])
Default: 000
Function:
Sets a cushion level below full scale. This setting is usually set slightly below the maximum (MAX[2:0])
threshold. The Limiter uses this cushion as a hysteresis point for the input signal as it maintains the signal
below the maximum as well as below the cushion setting. This provides a more natural sound as the limiter
attacks and releases.
