GENERAL

The Shure Model M267 is a microphone mixer-remote am- plifier specifically designed for professional applications. The excellent performance, versatility and features of this com- plete, compact console make it an ideal choice for studio, re- mote, or sound reinforcement use, and as an add-on mixer for expanding existing facilities. It is also ideally suited for use with audio and video tape recorders to provide multiple microphone inputs.

Features:

•Wide, flat frequency response and extremely low distor- tion up to +18 dBm output

•Extremely low noise and RF susceptibility

•Four switchable microphone- or line-level balanced-line inputs with individual gain controls and low-frequency roll- off switches. MUMETAL shielding on input transformers

•Feedback-type input gain controls for maximum clipping levels and dynamic range

•Output switchable for line or microphone level

•Built-in switchable peak limiter cuts output overload dis- tortion, adapts to power supply voltage

•LED indicator shows limiter operation or overload with limiter defeated

•Externally adjustable limiter threshold (±4 to +18 dBm)

•VU meter calibrated for +4 and +8 dBm with range switch. Illuminated with ac operation

•Ac or built-in battery operation. Noiseless automatic switchover to battery in case of ac line failure. Battery test without program interruption

•Front-panel headphone level control and monitor jack drives almost any stereo or mono headphones; output can be additional unbalanced line feed to drive a tape re- corder or power amplifier

•Direct mix bus for stacking units

•Automatic muting prevents speaker damage during turn-on and -off
