The Shure Model M367 is a six-input, portable microphone
mixer/remote amplifier specifically designed for professional ap-
plications in electronic news gathering (ENG), electronic field
production (EFP) and general audio mixing. It sets a new stan-
dard for portable mixer performance and features. Exceptionally
low–noise design makes the M367 ideal for use with digital trans-
mission links and digital video/audio recording media, including
ISDN and DAT. Compact and rugged, the M367 is built to with-
stand the most demanding field production conditions. In addi-
tion, its excellent performance, versatility and features make it an
ideal choice for studio, remote, or sound reinforcement use, and
as an add-on mixer for expanding existing facilities.
Each M367 handles up to six microphones or line-level sig-
nals. Any high-quality, low-impedance, balanced microphone
using a dynamic or condenser* transducer (including wireless
and shotgun types) can be used. Additional M367 or other Shure
mixers can be linked using the rear–panel mix bus jacks.
The M367 is supplied with rubber feet, detachable power cord,
and spare power line fuse. Model A367R is an optional rack
mount kit enabling the M367 to be mounted in a standard 483
mm (19–inch) audio equipment rack (two rack units).
The M367 is supplied for operation at 100–120 Vac, 50/60 Hz,
and the M367E for operation at 220–240 Vac, 50/60 Hz. Each
model is internally switchable to the other's operating voltage
range.
*Self-powered or operable on 12 or 48 Vdc phantom power.
