IRIS-Net DIGITAL MATRIX | en 443 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. Element 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. 0.0 dBu -9.0...+21.0 The THRESHOLD parameter defines the level value at or which the limiter sets in. Signal levels below the threshold dBu or 0.775 V 0.275...8.696 V 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 Bosch Sicherheitssysteme GmbH 0...50 ms ATTACK defines how fast the gain is reduced after the signal exceeds the threshold level.
