Four models for every application. Pick the Graphi-Q2 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. RS232 remote computer control, 20 on-board program memories, and remote switching via contact closures are standard in all

Graphi-Qs (blank or active front panel). No other professional audio device gives you this level of control, this superb audio quality, at this low price.

The single-channel Graphi-Q2s 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 for 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.

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’ 32-bit floating-point SHARC™ digital processor powers every Graphi-Q, allowing simultaneous use and control of these eight essential functions.

…or Flexible Control

FFrro ntt p ellss:: The GRQ3121 and 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.

G RQ em e S offttw nd wss ™ :: A whole new look and improved navigation and graphic editing. Real-time display of all filter editing, including the new Crossover. Control up to 16 channels of Graphi-Qs via computer. Every Graphi-Q2 includes serial port and software for remote control, and remote switching connections for preset recall.

Sabine’s GRQ2 Remote software gives you instant access to all front panel controls and to an additional layer of functions.

Built-in Flash RAM lets you upgrade Graphi-Q2 firmware and software with the touch of a button. And all Graphi-Q2s are now controllable via software.

A S ma arrttLLiivve ™ :: All Graphi-Q2s are controllable within SmaartLive.

The all new GRQ2 Remote for Windows gives you the same handson feel as the front panel, and allows you to control up to 16 channels of Graphi-Qs simultaneously. All the major functions you need are there on the screen, ready for use. You rarely have to leave the main screen or pull down a menu to access the control you need.

We’ll even show you a line graph of your gain structure, graphically displaying every parameter.

Using your computer as a platform gives you unlimited memory storage of Graphi-Q2 files. Each file holds up to 20 presets, and you can transfer these settings to the on-board memory locations within each Graphi-Q2. You can also access all Graphi-Q2 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 no other access to any Graphi-Q2 controls. And you can print a threepage report that records the setting of every parameter in the

Graphi-Q2, including a frequency response curve.

Every Graphi-Q2 includes the new SMARTFilters version of Sabine’s patented FBX Feedback Exterminator. Sabine pioneered the automatic feedback controller in 1990, and invented the digital feedback controller in 1991. The FBX in the Graphi-Q2 is the state-of-the-art in automatic feedback control – fast, reliable, and transparent.

S MA errss have laser-like accuracy and resolution, targeting feedback while leaving your sound untouched. That means the

FBX is the right choice when you want to control feedback during the show, not just at setup time. This innovative solution identifies feedback and places super-narrow filters with one Hz resolution, during setup and during the program. This real-time performance distinguishes the FBX from all other feedback controllers. Each filter is custom-made at the moment of feedback, and is placed just deep enough to remove the ringing tone.

Speed of feedback elimination, shown as amplitude over time: The top chart shows the speed of a competitor. Note slow reaction time and longer time to eliminate the feedback. The bottom section shows the much faster FBX.

The new GRQ2 Crossover allows for easy editing of your all your crossover parameters, and allows for custom filter and slope selection on both sides of the crossover point. Your settings are displayed in real-time on the

Response Curve display, which also selectively displays the graphic EQ, high & low cut, parametric, and FBX filters, for both the A and B channels, in any combination.

GRQ2 Crossover

Parametric Filter control allows you to switch any filter from fully-programmable parametric to Fixed or

Dynamic FBX filters.

In Automatic FBX

Setup Mode, the filters – just sit back and watch as the unit

GRQ2-Remote Software Main Screen raises the gain, places all the FBX filters at a super-quiet level, and displays the added gain you get, all in real time.

Graphi-Q2 automatically sets up the FBX

Use the BYPASS and ACTIVE matrix to manage the status of every

Graphi-Q2 function. Make fine adjustments to other Graphi-Q2 functions, including graphic EQ filter widths from ½ octave to one full octave, and adjust attack, release, and knee on the compressor.

Trra nssp arre So un your sound, and the patented FBX makes thousands of calculations per second to accurately distinguish music from feedback. Other feedback controllers may do fine in setup, but they will eat your sound alive during the show because they lack the ability to separate your sound from feedback. The laser-like FBX targets only the feedback and preserves your sound.

err C on tion, lock or unlock your fixed filters, and reset your dynamics either manually or with the new Dynamic Filter Release Timer.

Change the sensitivity of the algorithm to suit your application. You can speed up the process in speech applications, or apply a more rigorous setting for orchestral and house of worship applications.

Q uiic & Q uiie ettu is ramped up. And the output of the Graphi-Q2 is limited, so your setup procedure is easy on the ears and completed in 30 seconds.

H erre ha hiiss m ea o yyo u:: More gain before feedback, increased clarity and intelligibility, more wireless microphone mobility, fast, easy setup, and adaptive, automatic feedback control.

No other audio device provides these benefits at this price.

Notes:

Below approximately 200 Hz the feedback filters become slightly wider to increase the feedback and rumble capture speed at these low frequencies.

2 Note: Inputs may be balanced or unbalanced.

For maximum output capability, outputs must be balanced (XLR or TRS). If either side of an output is grounded, the peak output and dynamic range will be reduced by 6 dB.
