RP252 Compressor/Limiter Gate
The RP252 is a professional, full-featured Compressor/Limiter that can
handle a wide range of signals. Variable threshold, compression ratio, attack,
and release controls make the Compressor/Limiter section complete for the
sound reinforcement or recording need. The Noise Gate section lowers the
output subtly, and the controls make it easy to set for any noise reduction
situation. The input and output XLR connectors have -10/+4 dB Level
switches.
