The SMR

821a is a professional

microphone and line level audio program
mixer intended for fixed installation
applications. This single‚ rack-mount unit
is designed to provide high-quality audio
performance using versatile control
options and a simple user-interface.
Engineered from the ground up with the
commercial sound systems contractor in
mind‚ the SMR 821a includes many
features for easy operation‚ installation
and servicing.

With three independent audio output
buses‚ the SMR 821a is perfect for
applications where zoned output and
simple monitoring is required. Six of the
eight inputs include high-quality
microphone pre-amplifiers and separate
gain controls. Additional rear panel
controls provide even more flexibility for
proper gain setup‚ output assign and
remote control features.

In stand-alone applications‚ the SMR
821a is a very powerful tool. Ease of use‚
external control options and a simple
user-interface make it perfect for many
applications where the end-user must
have access to the audio system. The
ability to link multiple units provides
even more flexibility for a wide range of
applications.
