PEAK-LIMITER (RCM-24)
A Limiter is used when the output signal must not exceed a specific peak level, independent of how much
the input level rises. Short attack times effectively limit overshoots. Limiters are often used as protection for the
components following them in an audio chain, i.e. to prevent an amplifier from clipping or protect loudspeaker systems
against mechanical damage. The characteristics of this Limiter are identical to those of the limiters used in Precision
Series power amps.

Default Range Description
This indicator signals in dB by how much the limiter
reduces the signal level. A red bar that increases from the
right to the left indicates the degree of gain reduction.

The THRESHOLD parameter defines the level value at
which the limiter sets in. Signal levels below the threshold
will pass through the limiter unaffected. As soon as the
signal level reaches or exceeds the threshold, signal
limiting sets in. Generally, the THRESHOLD of the limiter
should be set some dB higher than the compressor’s
threshold to effectively limit high level peaks. Entering the
threshold value is possible in dBu or V. The value can be
entered in either fox and will automatically be converted in
the other.
5 ms 0...50 ms ATTACK defines how fast the gain is reduced after the
signal exceeds the threshold level.
