6.37 Limiter Min/Max Thresholds (Address 2Ch)
6.37.1 Limiter Maximum Threshold
Sets the maximum level, below full scale, at which to limit and attenuate the output signal at the attack
rate (LIMARATE -
“Limiter Release Rate” on page 86 ).
Note: Bass, Treble and digital gain settings that boost the signal beyond the maximum threshold may
trigger an attack.
6.37.2 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 86 ) until levels lie between the LMAX and CUSH thresholds.
Note: This setting is usually set slightly below the LMAX threshold.
