Gentner PSR1212 User manual
DIGITAL MATRIX MIXER WITH AUDIO PROCESSING
PSR1212
PRODUCT OVERVIEW FEATURES/BENEFITS
100 percent digital signal processing.
12 x 12 matrix with level control at
the cross points.
Twelve line output channels. All
output levels are adjustable and can
be muted.
Eight audio processing buses that can
be placed anywhere within the matrix
mixer audio path.
Eight-channel automatic microphone
mixer with four line inputs. The mixer
operates across linked units.
Input gain, configurable audio
processing, muting, and automatic
mixer are programmable per input
channel (inputs 1-8 only).
Configurable audio processor with four
filters on inputs 1-8.
All interconnected devices can be
accessed, controlled, and programmed
via a single RS232 connection.
Program, operate, and diagnose with a
connected PC (direct or via modem)
or other serial remote-control device.
32 programmable presets for instant
configuration changes.
Allows grouping of mics across four
automatic mic mixers within a single
PSR1212.
Internal room combining capabilities.
The PSR1212 is a highly-advanced
twelve-by-twelve digital matrix mixer
with audio processing. It utilizes an
internal macro language and 32 user-
definable presets to quickly adapt to a
variety of sound reinforcement and
room-combining applications in
auditoriums, stadiums, theatres,
gymnasiums, hotel/convention centers,
conference rooms, training rooms, and
boardrooms.
The PSR1212 facilitates local and
remote PC setup and diagnostics.
Microphone inputs can be individually
customized to gate on and off as you
wish, while Automatic Gain Control
keeps the overall sound level consistent.
All microphone mixing parameters can
be customized and any combination of
inputs can be routed to any combination
of outputs, allowing flexibility in
accommodating different applications
and customer requirements.
Adjustments in routing, level, and other
functions can be made through an
RS232 serial interface or buttons
connected to the rear panel.
The PSR1212 features eight audio
processing buses. Each bus has 15 filters
which can be configured as parametric,
high pass, low pass, CD horn, high
shelving, low shelving, all pass, or
crossover. Each bus also includes delay
and compressor/limiter functions. This
allows you to tailor the PSR1212’s
audio response to optimize the audio
quality and fidelity characteristics of a
wide variety of sound reinforcement
systems.
Macro Pro, a scripting language, enables
sophisticated control without the need
for an expensive external control system.
This gives you real-time flexibility to
meet a variety of audio reinforcement
and room-combining requirements.
A digital audio and control bus allows up
to eight PSR1212s to be connected and
controlled as a single unit.
