Rolls SL33b Stereo Program Limiter The new SL33b Stereo Program Limiter provides smooth dynamics processing for professional and consumer audio equipment. It features 1/8" stereo and RCA inputs and outputs for easy connection to any audio situation. Since there is no audio level standard for consumer audio, the SL33b keeps the levels maintained for a more comfortable listening environment. At the heart of the SL33 is a powerful compressor/limiter integrated circuit which provides automatic program limiting for unobtrusive and natural level control. A Threshold control has been provided to set the level at which the process engages, and a Makeup Gain control offers output leveling.
