BASS PEAK LIMITER
Opens the BASS PEAK LIMITER menu shown above, which can
be used to set amplitude limits for all speakers to which low
frequencies are redirected, including the subwoofer.
The SDP-5 is equipped with an internal limiter that prevents low-
frequency output signals from exceeding a designated level. 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.

SETUP
CAL NOISE ON, OFF
Determines whether the bass peak limiter is set with an internal or
external source. When set to ON, the SDP-5 activates an
internal calibration noise signal to set the limiter. When set to OFF,
the SDP-5 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.
