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

GRQ2 Remote Control Software for Windows: Control up to 16 GRQ2 via computer. Includes serial port and software for remote control, and remote switching connections for selecting user-defined presets. You can download the latest release of GRQ2 Remote Control Software and/or the Upgrade Wizard for flashing your GRQ2 with the latest release of GRQ2 Firmware.

FREE Firmware Upgrades: GRQ2 firmware can be updated without losing any of your presets! And it's FREE!

More Important Graphi-Q2 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.

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.

Sabine GRAPHI-Qs use FLASH RAM to store the internal firmware (think of it as the operating system that runs the GRAPHI-Q and GRAPHI-Q2). Periodically we may update that firmware to make improvements in the features and functions of the GRAPHI-Qs. You can take advantage of these upgrades on your own. Download the Upgrade Wizard, run the setup, and follow the instructions to upgrade the internal firmware of your GRAPHI-Q or GRAPHI-Q2. The Wizard will tell you if there is an appropriate upgrade available for your GRAPHI-Q or GRAPHI-Q2. And remember, keeping your GRAPHI-Qs up-to-date with the latest and greatest firmware/software is FREE from Sabine!

NOTE: On full front panel Graphi-Qs, GRQ3101 & GRQ3102 for the GRAPHI-Q or GRQ3121 & GRQ3122 for the GRAPHI-Q2, you can check the release version of your firmware by powering down and up, and then checking the digital delay window on the unit. It will display the 3-digit firmware version briefly. Remote Control only Graphi-Qs, GRQ3101S & GRQ3102S or GRQ3121-S & GRQ3122-S, will display the firmware version by clicking About in the menu bar.

Firmware version 5.00 works on all Graphi-Q models.
GRAPHI-Qs can now be networked together; however, the GRAPHI-Q2 must be first in the chain of the network when linking to a
GRAPHI-Q.

Current Released Version of GRAPHI-Q2 Firmware

Version 2.25 — July 15, 2005
Fixes a few minor bugs. Loading Front Panel mode (Preset 1) will now load the last settings used when in Front Panel mode instead of system defaults. Setting the number of Fixed filters is now faster. Caution: Upgrading to this firmware will clear your user presets, so please save these to a file on your computer before performing the firmware upgrade. Download version 2.25 and follow the easy procedure using the Upgrade Wizard.
