• HOLD [0s - 500ms]
Sets a timer which starts when the signal falls back below threshold and, once the time has elapsed, allows the limiter to
release, thereby preventing the limiter from releasing prematurely. When AUTO is on, this parameter is ignored and set
dynamically.
• RELEASE [360dB/s - 5dB/s]
Sets the rate at which the limiter will come out of gain reduction once the signal level drops back below threshold and
the hold time has elapsed. Release is measured in dB per second. For example, if RELEASE is set to 5 dB/Sec, and the
signal has 10dB of gain reduction, the release time is 2 Seconds. The release range is from 360 dB/Sec to 5 dB/Sec.
When AUTO is on, this parameter is ignored and set dynamically.
• PEAK STOP PLUS [OFF, ON]
Enables PeakStopPlus ™ and changes the limiter from an RMS (Root Mean Squared), or averaging limiter, to a peak
limiter. The difference between these two types of limiters is in the signal that is being fed to the detection circuit
of the algorithm. The detector of an RMS limiter is “looking” at an average signal, while a peak limiter “looks” at the
instantaneous (peak) signal. An averaging limiter will be less responsive and will not actually limit every peak, where a
peak limiter will.
PeakStopPlus involves a two-stage process of dynamic limiting. The first stage of PeakStopPlus 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 PeakStopPlus OVERSHOOT control by more than the overshoot amount,
and that it will not introduce harsh artifacts. 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 needed to keep
the output signal below the ceiling set by the Instantaneous Transient Clamp. The OVERSHOOT parameter sets the
amount of overshoot for the Instantaneous Transient Clamp.
• OVERSHOOT [2dB - 6dB]
Sets the amount of transient overshoot allowed when PEAK STOP PLUS is turned on. Lowering this parameter will
provide additional protection, but may subtly affect the sound as transients become softened.
