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.
This has various signs of paint wear, scratches and staining -
typical for a vintage mixer. Overall is in presentable condition.
It also includes a rackmount setup with a custom XLR connector and
cable on the left. Tested in good working order with battery and
AC power use. Pots were cleaned and not scratchy like is typical
in many used examples. Overall this works to the specifications
this was designed for.
