The RB-SL2 is a stereo, or twin independent mono, VCA limiter for use in news-rooms and other locations where the correct level into recording equipment is required, but not necessarily under the control of an engineer, for example, for overload protection. It can also be used as an inexpensive main output limiter for small scale radio stations, hospital radio and student radio. The XLR-3 electronically balanced inputs and outputs can be wired unbalanced to accept an output from domestic equipment.
Product Features
Balanced XLR inputs and outputs.
Stereo or mono operation, can be used as two mono limiters.
Input gain & threshold limit controls.
Typical Applications
Limiting program output from a radio studio mixer, school radio audio output limiter.
