The Shure SCM268 4-Channel Microphone Mixer offers simplicity and routing flexibility in a convenient, compact, and rugged enclosure. The SCM268 features 4 high quality transformer-balanced XLR inputs and mic/line level switchable XLR output. Transformer balanced I/O provides maximum audio gain, minimizing hum and line noise. Two stereo paired (4 mono) RCA inputs except line level signal from consumer audio devices such as CD and cassette players, DVD players, VCR's 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.
