Limiter Control 1, Min/Max Thresholds (Address 27h)
7.23.1
Limiter Maximum Threshold
Sets the maximum level, below full scale, at which to limit and attenuate the output signal at the attack
Note:
Bass, Treble and digital gain settings that boost the signal beyond the maximum threshold may
trigger an attack.
7.23.2
Limiter Cushion Threshold
Sets the minimum level at which to disengage the Limiter’s attenuation at the release rate (LIMRRATE -
“Limiter Release Rate” on page 54) until levels lie between the LMAX and CUSH thresholds.
Note:
This setting is usually set slightly below the LMAX threshold.
7.23.3
Limiter Soft Ramp Disable
Configures an override of the digital soft ramp setting.
Note:
This bit is ignored when the DIGZC (“Digital Zero Cross” on page 45) is enabled.
