APPLICATIONS
The SCM810 has numerous applications in sound rein forcement,
audio recording, and broadcast. In any speech pickup application
where multiple microphones are required, the SCM810 dramatically
improves audio quality. Automatic operation allows an individual talk-
er's voice to rise above background noise and reverberation to be-
come clearer and more intelligible.
Each SCM810 handles up to eight microphone- or line-level sig-
nals and two aux-level signals. Any high quality, low-impedance, bal-
anced dynamic or condenser microphone (in cluding wireless) can be
used. Additional SCM810 mixers (up to 50) can be interconnected us-
ing the rear-panel link jacks. Non-automatic (manual) operation is also
available.
