BASS PEAK LIMITER
Opens the BASS PEAK LIMITER menu, which is used to set ampli-
tude limits for all speakers to which low frequencies are redirected,
including the subwoofer.
The AV1 is equipped with an internal limiter that prevents low-fre-
quency 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.
CAL NOISE ON, OFF
Determines whether the bass peak limiter is set with an internal or
external source. When ON, the AV1 activates an internal calibration
noise signal to set the limiter. When OFF, the AV1 deactivates the
internal calibration noise test signal. An external calibration source
such as an audio calibration disc is required to generate a noise sig-
nal to set the bass peak limiter.
