Marketing Information |
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 1/4-inch
send/receive insert jack.
This full-featured, non-automatic version of the SCM810 features
adjustable channel EQ, quick microphone connection and linking
capability for up to 32 microphones. |
