M367
Specification Sheet
DESCRIPTION
The Shure M367 is a portable, six–input, two–output (mono),
battery–powered microphone and line level mixer/preamplifier. Its
transformer–isolated design, low–noise performance, and compact and rugged construction make the M367 an ideal choice for
studio and mobile broadcast, electronic news gathering (ENG),
and electronic field production (EFP) applications.
This versatile mixer can also be used for:
S digital transmission links
S digital video/audio recording media (ISDN, hard disk re-
cording, and DAT)
S sound reinforcement
The M367 comes with rubber feet, detachable power cord, and
spare power line fuse. It can be rack mounted using the optional
Model A367R rack mount kit.
FEATURES
S Six selectable mic/line inputs
S Selectable mic/line output and dedicated line output
S Transformer–balanced inputs and outputs for superior
rejection of RFI and electromagnetic hum
S Professional mechanical VU meter—LED backlighting for high
reliability, no lamp replacement
S Headphone monitoring (1/4”, 3.5 mm)
S Output peak limiter with switchable threshold and bi–colored
LED indicator
S Peak indicator LED, and switchable low-cut filters on each
input
S 1/4” return monitor input
S AC power or (2) 9V battery operation
ADDITIONAL FEATURES
S 48 V or 12 V phantom power for condenser microphones
S 1 kHz tone oscillator
S Mutes all input channels when activated
S Tone level control is on the master
S Wide–range input gain controls handle hot signal levels
without attenuators
S Customized operation via internal DIP switches, trim pots, and
optional alternate wiring
S Battery check switch and low battery warning indication
S Power-on LED
S Input expansion via mix bus jack to link M367s or other mixers
S Rugged all metal chassis with protective end caps
S Detachable ac power cord
