ALC and Excursion Limiter Release Time
Sets the release time for both the ALC and Excursion Limiter. See the Automatic Level
Control section for ALC release times. Excursion limiter release time is defined as the
time required to slide from the high corner frequency to the low corner frequency.
Excursion Limiter Threshold
Measured at the Class D speaker amplifier outputs. Signals above the threshold use the
upper corner frequency. Signals below the threshold use the lower corner frequency.
