Sabine Feedback Exterminators

Your graphic EQ is fine for shaping sound, but if you use it to control feedback, the width of its filters means you may be removing a lot of good stuff too. An FBX-1020Plus or 2020Plus, placed in front of your power amp, senses feedback and, in less than a half-second, places a super-narrow adaptive digital filter on the resonating frequency. It’s automatic and v-e-r-r-r-y precise.

This will help audio pros anywhere. You get feedback control and increased clarity. At last you can crank up those monitors. Connectors are XLR and 1/4" TRS, balanced and unbalanced. The FBX 2020Plus is a dual mono version with a few extra features thrown in.

The FBXSOLO is a miniature version of the 1020Plus and 2020Plus, controlling feedback on one input channel. Pack one with your wireless mic setup. Monitor engineers can patch one on any offending channel. Mount up to six in a rack tray. Choose line or mic input versions; the latter has a pre-amp and phantom power.

Sabine Real-Q2

No matter how long you spend at setup, it’s impossible to anticipate every change in the acoustics of a performance space. Wouldn’t it be great if someone came up with a sub-audible noise generator so you could continue the real-time analysis during the concert? Then you could measure and compensate for changes in the sound field during the performance. While we’re dreaming, why not hook the RTA directly to the house EQ and let it push the sliders automatically to maintain your EQ curve in real time?

The Real-Q2 only adjusts for changes in the room acoustics, not changes in the mix. You keep full control of the mixing console, program EQ, FBX-Feedback Exterminators, and all other signal processors that precede it in the signal path. If you decide to add bass to the mix, the Real-Q will not compensate. However, if the audience absorbs the bass, the REAL-Q automatically boosts the equivalent amount.

Real-Q2 installation and operation is about as easy as using your CD player. Just patch it in and in a few keystrokes, the Real-Q2 automatically analyzes and flattens the room, or matches any curve you create. Then it monitors and compensates for any changes in the auditorium - changes that will other

wise ruin your sound.  On the other hand, if you want full control, the Real-Q2 provides a full-featured RTA and noise generator, digital graphic EQ, graphic display of the room’s response curve, and storage for 100 different response curves.

The strength of the Real-Q2 algorithm is its combination of simplicity and robustness. Since it generates and measures its own reference tones, it is independent of changes in the mix; in fact, the Real-Q2 cannot hear the program material during analysis. Program level, signal processing and even reference microphone placement do not affect the measurements. The REAL-Q2 operates in the

background to constantly provide the correct room equalization-indefinitely.

Sabine Graphi-Q 3100 Graphic Equalizer

The Graphi-Q 3100 Graphic Equalizer Series combines four 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 Graphi-Q’s 31-band digital graphic EQ.  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 Graphi-Q digital compressor/limiter. Finally, add 3 to 9 dB extra gain and automatic feedback control with Sabine’s patented FBX technology.  The Graphi-Q gives you instant hands-on, front panel control for every function, or choose the blank front panel versions for the ultimate in system security and economy.

Rane Realtime Analyzer

The Rane RA 27 Realtime Analyzer is a single rack-space unit providing 27 bands of realtime frequency/amplitude information in a 3-LED vertical band format. Broadband signals applied to either the Microphone or Line inputs of the RA 27 are divided into 1/3-octave increments by ANSI Class II filters. The outputs of these are applied to LEDs on the front panel to visually indicate the amplitude of each band. In operation, the RA 27 is used to visually judge the character of the Pink Noise signal received by the measurement microphone. The operator may now adjust a 1/3-octave equalizer for optimum response of a sound system based on the readings presented by the LED display.

The rear panel of the RA 27 includes a Pink Noise Output jack, Aux Mic Input (XLR), a Line Input (1/4" unbalanced), and a recessed Pink Noise Level adjustment. The included Rane MIC 1 condenser microphone, complete with 40-foot cord, is a professional quality back-electret condenser microphone with an omnidirectional pickup pattern. Its power is provided from the RA 27, but may be powered via batteries for other uses.
