Enjoy big value in a compact unit with the SCM268 from Shure. This 4-channel microphone mixer delivers awesome performance value and pristine audio quality, boasting low noise and a flat frequency response, and featuring 4 transformer-balanced inputs, 5 -10 dB line-level inputs, 12V phantom power for condenser microphones, and integrated low-cut filters on mic inputs. This and many more benefits make the SCM268 an ideal mixer choice for smaller-scale applications that need affordable mixing solutions, including meeting rooms, houses of worship, live broadcasting, educational paging and PA, as well as sound system rental companies.

Get half a dozen transformers and more in a half-rack space with the SCM268. This mixer boasts 6 built-in transformers, 4 transformer-balanced XLR mic-level inputs, 1 transformer-balanced XLR mic/line output, 1 unbalanced aux level output (Phono connector), 5 unbalanced aux level inputs (Phono connectors), and 1 internal low stray field, toroidal power transformer. The SCM268’s transformers protect your signals from RF interference while preventing ground loops for ultra-quiet mixer operation. Meanwhile, the internal toroidal power transformer dispenses with any need for annoying "wall wart." 

Other features of the SCM268 include an LED peak output meter and an included IEC power cord connector. The entire unit is enclosed in rugged housing and features durable rack mounting hardware for permanent installation. It fits into a half-rack space that makes it easy to fit into any size of audio setup.
