Note:
Attack and Release controls operate together and in conjunction with the Compression ratio control.
Changing one control may necessitate changing another setting.
Using PeakStop
®
/PeakStopPlus
™
The Stop Level control sets the maximum peak output level of the 160SL irrespective of any other control.
PeakStop consists of a sophisticated voltage-controlled Instantaneous Transient Clamp
™
that produces a minimum
of audible distortion. It rounds the corners of a peak rather than cutting it off sharply, as “clippers” do. By making
a signal’s leading and trailing edges curved instead of sharp corners, it reduces the amount of higher odd-order,
offensive-sounding harmonics that conventional clipping causes.
The level at which PeakStop is activated is adjustable from +4dBu to +30dBu. Note that small signal excursions
above the set value of PeakStop are possible, to allow the rounding to occur. Therefore, for applications where
you must not exceed a given ceiling, set the PeakStop control 1 to 2dB below the ceiling.
To disable the PeakStop function, set the control to OFF (>+30dBu) (i.e: above the maximum output level of the
160SL).
PeakStopPlus is made up of two seperate parts. The first stage is the Instantaneous Transient Clamp
™
which clamps the signal
with a soft logarithmic clamp function. This logarithmic function assures that the signal will not exceed the level set by the
PeakStopPlus
™
Level control by more than 2 dB typically, 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
™
. Note, since the PeakStopPlus
™
limiter is a fail-safe limiter it must come after the Output
gain control. If the output gain is set too high as compared to the PeakStopPlus
™
Level control, continuous limiting can
occur.
While PeakStopPlus
™
is typically used as a protective function, creative effects can be achieved by intentionally driving the
signal into heavy PeakStopPlus
™
limiting. Great care has gone into the design of the PeakStopPlus
™
limiter to keep it acousti-
cally transparent. Appropriate use of it can protect your gear while keeping the signal free of artifacts.
