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 except line level signal from consumer audio devices such as CD and cassette players, VCR’s, 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.

  • Quality Inputs: Features 4 balanced XLR mic preamps resulting in high input gain and low noise floor.

  • AUX Line Inputs: 4 additional line level inputs via RCA connectors are provided. These inputs are perfect for adapting consumer level devices such as CD and cassette players, audio from VCR's etc.

  • 12V Phantom Power: The SCM 268 provides 12V phantom power for condenser microphones.

  • Compact Rugged Design: The SCM 268's rugged, compact design provides maximum portability without sacrificing the ruggedness.
