Feature Overview

• Extensive Meter bridge provides signal level metering of
LEFT, RIGHT, CENTER/MONO, SOLO LEFT, SOLO
RIGHT, and 8 SUBGROUPS. The LEFT, RIGHT, CEN-
TER/MONO and SOLO meters are of a larger size and are
centered on the meter bridge. For 64 and 52 positions frames
sizes only, metering is also provided for the 8 AUX SENDS.
All level meters are of the mechanical moving coil type, are
referenced to +4 dBu, and are illuminated by long-life LED's.
• Variable Hi-Pass filter on input channels allows for precise
control over a signal's unwanted low frequency content.
• Channel inserts are implemented using separate 1/4" TRS
jacks for send and return. An insert switch with indicator LED
allows A/B comparisons and signal processor bypass.
• Switchable Q on Hi Mid and Lo Mid EQ bands adds more
flexibility to an EQ circuit that already offers four sweepable
bands and selectable peak/shelving on the Hi and Lo bands.
• Dual concentric send controls for auxes 1&2, and 3&4, in
addition to sends 5-8 allow each input to send onto any or all
of the 8 aux buses, while occupying a minimal amount of mod-
ule space.
• AUX pre/post switches. The first four aux sends can be
selected to be pre or post by the Aux 1-4 pre/post switch. In
addition, Aux pairs 5&6 and 7&8 each have designated
pre/post switches. The Pre source is internally selectable to
Pre-EQ or Pre-Fader.
• Discreet bus assignments and L-C-R (Left-Center-Right)
panning. Input channels and Effects Returns incorporate an
uncompromised bus assignment section. Features include true
L-C-R panning, standard panning, clean mono bus, discrete
bus assigns, and panable stereo bus assigns.
• Each input channel features a five-segment LED array,
including a signal present LED, three signal level LEDs and a
peak indicator.
• SSM/PMI high-quality preamplifiers on balanced micro-
phone/line inputs for uncompromised audio quality and relia-
bility. All IC's within the audio path are socket mounted for
easy upgrade or service.
• 48 Volt switchable phantom power on all microphone inputs.
• Optional transformers available on all microphone inputs and
on Group, Left/Right, Mono, Aux, and Matrix outputs.

• Mono/Stereo PFL (Pre-Fader-Listen) and AFL (After-Fader-
Listen) system. When a stereo module is used, the signal is
monitored in stereo while mono modules are monitored in
mono. Selected outputs may be monitored in mono or as stereo
pairs.
• Standard frame sizes include 44, 52, and 64 positions. The
Master section occupies four positions and Groups occupy
eight positions.
• Any frame size may be ordered short loaded for later expan-
sion.
• Direct access to Group Mix buses allows expander mixers to
be easily patched into the console.
• Full facility effects return section includes Gain Control to
handle a wide range of input levels, High and Low frequency
EQ, Aux Sends, expanded bus assignment section, and level,
pan, PFL and Mute controls.
• Mute system on input channels is designed to mute both pre-
and post-fader signals including those Aux sends used as mon-
itors. When muted, PFL circuitry, Peak, Level, and Dynamic
Signal Present LED indicators remain fully operational.
• Twin power supply capability with automatic changeover
backup for uncompromised reliability. Second power supply
optional.
• Optional Matrix modules available, useful for the creation of
independent mixes using the main outputs and External Input
as signal sources.
• Optional Stereo Input modules available, useful for remote
feeds, effects inputs, and other mic or line level signals requir-
ing stereo handling.
• Comprehensive Talkback section allows access to all primary
console outputs. Additional access provided to an external
location such as an on-stage monitor mixer system. External
signals can also be assigned into the talkback system including
Oscillator and Pink Noise source inputs.
• Left/Right summing switches to Aux 1-2 and Aux 3-4 allow
for simple setups of mixes by allowing Left/Right signals to be
blended with auxiliary mixes when used in recording applica-
tions. In contracting applications, this feature allows these Aux
outputs to act as additional distribution amplifiers for the
Left/Right signals.
