Shure SCM268 Four-Channel Transformer Balanced Microphone Mixer with Phantom Power, AC only, Half Rack Space, Single, and Dual Mount
The Shure SCM268 4-Channel Microphone Mixer offers ease and routing flexibility in a suitable, compact, and rugged enclosure. The SCM268 is featured with 4 high-quality transformer-balanced XLR inputs and mic/line level switchable XLR output. Transformer balanced I/O offers maximum audio gain, minimizing line noise and hum. Two stereo paired (4 mono) RCA inputs accept line-level signals from consumer audio devices such as CD and cassette players, VCRs, DVD players, etc. Also provided is an additional, independent AUX line-level input with level control via a single RCA connector. Six sealed rotary pots provide level control for mic channels 1 through 4, AUX input channel, and Master. The SCM268 also provides 12V phantom power for condenser microphones.
