BASS PEAK LIMITER
Opens the BASS PEAK LIMITER menu, which can be used to set
amplitude limits for all loudspeakers to which low frequencies are
redirected, including the subwoofer.
The MC-4 is equipped with an internal limiter that prevents low-
frequency output signals from exceeding designated levels. This is
essential for Dolby Digital and DTS(-ES) input sources that produce
low-frequency peaks at much higher levels than 2-channel
sources. In home theaters, the subwoofer and its associated
amplifier might not be able to reproduce these levels without
overloading.

CAL NOISE
ON, OFF
Determines whether the bass peak limiter is set with an internal
or external source. When ON, the MC-4 activates an internal
calibration noise signal to set the limiter. When OFF, the MC-4
deactivates the internal calibration noise test signal. An external
calibration source such as an audio calibration disc is required to
generate a noise signal to set the bass peak limiter.
