SCM800/SCM800E Microphone Mixer
Specification Sheet
SCM800/SCM800E EIGHT-CHANNEL MICROPHONE MIXER

SYSTEM OVERVIEW
The Shure Model SCM800 is a full-featured, eight-channel microphone mixer for sound reinforcement, general audio recording, and
audio-visual systems. Any low-impedance, balanced dynamic or condenser microphone, including a wireless microphone system, can be
used with the SCM800 mixer.
Each SCM800 accepts up to eight microphone- or line-level inputs
and one aux-level input (two input jacks feed the same channel). Up
to four SCM800 mixers can be linked to provide up to 32 input channels. Each input channel has a two-band equalizer, switchable microphone- or line-level operation, switchable 48 V phantom power, and a
1/ -inch send/receive insert jack.

The SCM800 operates on 120 Vac power; the SCM800E operates
230 Vac power. Both models are supplied with rack-mounting hardware, link cable and removable block terminal connectors. An accessory rack panel adapter (Model RKC800, available separately)
converts the removable block input and output connectors to XLR
connectors, and the Aux connectors to phono jacks.
