The Crest AM-811 is a high quality automatic mixer with
eight transformer balanced mic/line inputs. Each chan-
nel provides a gain control, 48 Volt phantom power (mic
inputs), low cut filter, activity/clipping LED, an aux send
control, and a choice between manual or automatic
operation. Each channel also provides a defeatable
insert point, five Volt TTL status output, and can be

simultaneously via an assignable mutebus. In addition,
channels one and two provide an adjustable priority
control.
The master section provides a gain trim control,
three1/9 octave sweepable notch filters, a downward
expander, transformer balanced outputs (main and aux)
and remote volume connections.
The AM-811 has
been designed to easily link multiple units together to
form a single mixer with many more inputs (16, 24,
32…). The AM-811 is supplied with a see-through plex-
iglass security panel to prevent changes to the
installer’s settings.
