STEREO WIDTH
The Stereo Width parameter is automatically set when running and completing the Setup
Wizard. It can also be manually adjusted by the system engineer and can be used to create
a “hyper-stereo” image when monitoring with headphones or stereo in-ear monitors.
Stereo Width can also be used to mono sum outputs for use with mono wedge monitors or
in-ear monitors. The Stereo Width parameter affects all outputs.
LIMITER
The limiter provides speaker and hearing protection. This menu allows the system engineer
to manually adjust the Limiter Threshold. The Limiter Threshold parameter determines the
level at which limiting will begin to occur.
When configuring the PMC16 in the Setup Wizard, the limiter may be set automatically,
depending upon the options selected. Only adjust the limiter threshold manually if you
are sure you want to change the setting or if you need to calibrate the limiter for speaker
protection.
The PMC16’s limiter utilizes PeakStopPlus™ limiting, which is a two stage limiter. The
first stage of PeakStopPlus limiting is the Instantaneous Transient Clamp, which clamps
the signal with a soft logarithmic clamp function. This logarithmic function ensures that
the signal will not exceed the level set by the “Overshoot” parameter by more than the
overshoot amount. The PMC16’s “Overshoot” parameter is fixed at 6 dB. The second stage
is a unique program limiter featuring Intelligent Predictive Limiting. Its function is to
monitor the input signal and intelligently predict the amount of gain reduction required
to keep the output signal below the ceiling set by the Instantaneous Transient Clamp.
