Graphi-Q2:
Eight DSP Products in One
The GRQ2 combines eight indispensable audio products
into one very affordable, all-digital package — with an easy-to-use
hands-on interface! With the touch of a fader you can shape your frequency
response using the GRQ2's 31-band digital graphic EQ. Need more
control? Use the parametric EQ to control your filter width,
depth and frequency. Time align your speakers with the digital delay.
Manage your system gain with the GRQ2 digital compressor/limiter. Finally,
add 3 to 9 dB extra gain and automatic feedback control with Sabine's
patented FBX technology.
Four models for every application.
Pick the GRQ2 that works for your setup. Choose instant hands-on, front
panel control or the blank front panel versions for the ultimate in system
security and economy. RS-232 remote computer control, 20 onboard program
memories, and remote switching via contact closures are standard in all
GRQs (blank or active
front panel). No other professional audio device gives you this level
of control, this superb audio quality, at this low price.
No Limits on DSP Power. You will never run out of DSP power because all GRQ2 functions run concurrently. Set as many filters as you need, and add as much gain management and delay as the job requires. There are no meters showing DSP usage, because you will never run out of power.
How do we do it? Our 24-bit A/D and D/A give the cleanest audio possible, and Analog Devices' new 32-bit floating-point SHARC digital processor powers every GRQ2, allowing simultaneous use of these eight essential functions:
- 31-band Digital Grahic EQ, with 6 or 12 dB range.
- Patented FBX Feedback Exterminator: up to 12 new FBX SmartFilters with Quick & Quiet Setup Mode.
- Parametric Filters, up to 12 with full graphic editing.
- High and Low Cut Filters.
- Crossover: 1x2, with Bessel, Linkwitz-Reily, and Butterworth filters, slopes to 48 dB.
- Limiter: Full-featured, including hard limiting for speaker protection.
- Compressor: Full-featured, switchable to stereo or mono.
- Delay: up to 1 second delay, adjustable in 20 microsecond increments.
New Graphi-Q2 Features!

Flexible Control
Front panels:
The GRQ-3121 and
GRQ-3122 provide hands-on, "analog style" front panel control
for your digital graphic EQ, high & low cut filters, FBX, Compressor,
and Delay. Sabine's Tweek 'n' Peek gives you an instant readout of your
every move on the front panel.
The GRQ2 digital delay provides
precise speaker alignment, with 20-microsecond resolution, at the touch
of a button. And you get dedicated bypass switches for FBX, EQ and Delay
with built-in LED indicators.
Sabine's GRQ2 Remote
Control Software gives you instant access to all front panel
controls and to an additional layer of functions. You can view and edit
frequency response curves, view edits before executing them, and take
advantage of unlimited GRQ2
file storage.

Features
GRQ2
Remote Control software includes a BYPASS and ACTIVE matrix to manage
the status of every GRQ2
function. Make fine adjustments to other GRQ2
functions, including graphic EQ filter widths, from ½ octave to
one full octave, and adjust attack release, and knee on the compressor.
We'll even show you a line graph of your gain structure, graphically displaying
every parameter.
The single-channel GRQ2s
have two outputs for maximum system flexibility. GRQ2
Remote allows you to independently choose which functions are active in
each of the two outputs. For example, you can use one channel of a delayed
speaker, and choose which other processing you want on that delayed channel:
FBX, compressor/limiter, or equalizers. You can have independent delay
or level settings on each output, or dedicate the outputs to the new 1x2
crossover. 
New GRQ2 Software: Crossover Interface
New GRQ2 Software Main Screen Interface
Using your computer as a platform gives you unlimited memory storage of GRQ2 files. Each file holds up to 20 presets, and you can transfer these settings to the on-board memory locations within each GRQ2. You can also access all GRQ2 memory locations via the back-panel Euro-Block remote switching connectors. Using a simple contact closure switch, you can offer scene change options to users who have other access to any GRQ2 controls, and you can print a three-page report that records the setting of every prarameter in the GRQ2, including a frequency response curve.
