General Description
The Shure Model SCM810/E is an eight-channel automatic microphone
mixer designed for use in sound reinforcement, audio recording, and broad-
cast applications. The SCM810 dramatically improves audio quality in any
application where multiple microphones are required. Any low-impedance
dynamic or condenser microphone (including wireless) can be used with the
SCM810/E. Multiple SCM810 mixers can be linked to other SCM810/E mixers,
as well as to Shure Models FP410, SCM410 and SCM800 mixers.
Each input channel has a two-band equalizer and three logic terminals. The
equalizer reduces unwanted low-frequency audio pickup and makes different
microphone types-lavaliers, boundary and handheld-sound similar. The logic
terminals can be used to control external devices. The SCM810 operates on
120 Vac power; the SCM810E operates on 230 Vac power. Each mixer is
supplied with a power cord, rack-mounting hardware, and a link cable.
