SHURE SCM268
DESCRIPTION
The Shure Model SCM268 is a transformer-balanced, four-channel mi-
crophone mixer. Its simple, compact design delivers superior perfor-
mance and exceptional sound quality with low noise and a flat frequency
response.
Versatile in all types of applications, the SCM268 integrates transform-
er-balanced XLR inputs, a switchable microphone/line level transform-
er-balanced XLR output, phono jack inputs and output, phantom power,
and an auxiliary input channel. It can function as a primary or add-on mix-
er for sound reinforcement, recording, broadcast, or audio-visual presen-
tation systems.
With the supplied hardware, the mixer's half-rack chassis mounts se-
curely in single or dual rackmount installations. For fixed installations, the
SCM268 can be fastened on or below a shelf, counter, or tabletop.
