DESCRIPTION
The Peavey Architectural Acoustics
A/A-8P
™
Preamp is a high quality mic/
line preamp with eight separate
transformer balanced inputs. Each
channel provides a level control with a
selectable mic or line inputs to
accomodate a wide range of input
levels.
The A/A-8P
™
front panel provides
immediate indication of signal status
with an activity and clip LED. Included
in each channel's signal path is a level
limiter which is preset at the optimum
input level for the MM-8840 and
MM-8830 Digital Interface. Also, each
channel provides industry standard
+48 volts phantom power. Both the
limiter and phantom power are user
enabled on a per channel basis with
convenient dip switches located on the
back panel. The inputs and outputs are
"Euro" type connectors. And, to reduce
unauthorized or accidental level
changes, we have provided tamper
resistant level controls that are installer
adjustable with a screw driver.
The A/A-8P is ruggedly packaged in
an industry standard 19" single rack
space unit.

Euro type connector, balanced low or high
impedance
