OMB AUDIO PROCESSOR COM LIM 50
Digital stereo generator, 5 bands audio processor and RDS
The OMB COM LIM 50 audio processor is the combination of a professional digital stereo generator (with more than 65dB channel separation), a high-dynamic adjusted limiter with stop band rejection bigger than 90dB above 75KHz and a 5 band equalizer. All these advanced characteristics provide a whole range of professional features really useful in all radio studios. This audio processor manufactured by OMB also includes a RDS/RBDS digital encoder and an optional digital audio input.
The COM LIM 50 audio processor is the combination of a professional digital stereo generator (with more than 65dB channel separation) and a high-dynamic limiter, with stop band rejection higher than 90dB above 75KHz. A 5-band equalizer is integrated, too. All these advanced characteristics give the COM LIM 50 an outstanding range of professional features, really useful in radio studios. It also includes RDS/RBDS digital encoder, and programming, visualization and control trough LCD display.
