Designed for connecting studio mics to the inputs of Hard Disc Recorders, the Rolls CL151 has all the input stage processing power you need and an unbalanced 1/4 inch line level output. The CL151 is, however, a very versatile processor and can be used in any application where you need single channel mic or line level input processing. The CL151 features a single channel mic preamp with both balanced XLR and unbalanced 1/4 inch inputs, switchable phantom power, a noise gate, a soft-knee compressor/limiter with Threshold, Ratio, and Output controls, Gate and Gain Reduction LEDs, and operates on the supplied AC adapter.
