The Shure M267 is a vintage professional 4 channel mic / line mixer, each with individual gain controls and low-frequency rolloff switches. Features include: wide/flat frequency response, low distortion up to +18 dBm output, low noise and RF susceptibility, switchable peak limiter, VU meter calibrated for +4 and +8 dBm with range switch (illuminated with AC operation), headphone output with level control, internally selectable 120/240V operation, automatic muting to prevent speaker damage, direct mix bus for stacking units, tone oscillator, and ability to run on either batteries or AC power. Inputs are XLR. This is a mono output mixer. Inputs on the Shure M267 do have phantom power available (via switch on rear called simplex) but note it is 30V not 48V like modern mixers, which should properly power many condenser mics, but results may vary with lower voltage this provides.
