IEM User Manual
The PeakStopPlus™ limiter is a fail-safe Limiter is the last module in the signal path. This place-
ment is to ensure that In-ear buds will not experience any unexpected or unwanted signal vari-
ance If the Output Gain is set too high as compared to the PeakStopPlus™ Level control, con-
tinuous limiting can occur. Great care has gone into the design of the PeakStopPlus™ Limiter
to keep it acoustically transparent. Appropriate use of it can protect your ears while keeping
the signal free of artifacts. During PeakStopPlus™ limiting a large “P” is displayed at the top of
the digital output meters.
Limiter On/Off
This parameter turns the PeakStopPlus™ limiter on and off.
Threshold -60dB to 0.0dB
This control sets the threshold level at which the PeakStopPlus™ Limiter circuit becomes active.
OverEasy® Off to 10 (per band or global)
There are ten levels of OverEasy® that can be used on the IEM's limiters.
Auto
When auto is turned on the IEM will continuously set the attack / hold / release controls itself.
Type PkStop+ or RMS
The Type parameter is used to select either the PeakStopPlus™ or RMS limiter.
Attack .01 to 200 m Sec
This is the speed at which the IEM limiter starts to compress the signal once it has crossed the
threshold. Set the attack time longer for lower frequency bands, and shorter for higher fre-
quency bands.
Hold 0 to 500 m Sec
Hold is the time the limiter stays in gain reduction after the signal level has dropped below
threshold. Hold is useful when you want the limiter to function for a period of time after it has
been triggered. Be careful not to set the hold time too long as it will not release in time.
Release 360 to 5 dB / Sec
Just like the release time on the compressor, the limiter's release time controls how fast the lim-
iter releases from gain reduction after the signal drops below the threshold. Set the release times
longer for lower frequency bands and shorter for higher frequency bands.
There are 5 bands of EQ on the IEM that can be used for something as subtle as sweetening a
mix to drastic changes. Bands 1 and 5 are shelves while 2 through 4 are fully parametric.
Within the EQ menu the following parameters are user adjustable.
