Sabine SL820 Instrument Level Feedback Exterminator

Manufacturer's Description for Sabine SL820 Instrument Level Feedback Exterminator

You want more gain? Increased clarity? Automatic feedback control? Want to save some money? Sabine has the answer: the new FBX-SOLO, a miniature version of the award-winning FBX-1020P Feedback Exterminator(R). You decide which inputs get precision, automatic feedback control and maximum gain, from one channel to all your channels.

The affordable and ultimate solution to feedback problems is now even better with the new FBX-SOLO 820 Series - the single-channel solution for feedback control. New features of the SOLOs include increased headroom, a programmable noise gate, & switchable input/output levels for more versatility.

The FBX-SOLO targets feedback without taking a big chunk out of your sound. Digital FBX filters are 10 times narrower than graphic EQ filters. You get back over 90% of the power you lose with a graphic EQ!

Like all the FBX Feedback Exterminators(R), the FBX-SOLO does what no other audio product can do: it automatically detects and eliminates feedback while leaving the sound crystal clear. The patented algorithm distinguishes music from feedback so it works even during the program, not just at setup time.

If you use your 31-band EQ just to shape your sound and let your FBX control feedback, you should expect up to 9 dB more gain and a dramatic improvement in the sound quality. Why When you pull down a graphic EQ slider to chase feedback, you also pull out a big chunk of your sound. FBX constant-Q filters are 10 times narrower than graphic EQ filters. Narrow filters mean more gain and more clarity. It's that simple.

Sabine SL820 FBX-Solo Features:
* For: Mixer Insert Points - Input Channel Or Sub-Group, Mics Or Instruments
* Powered Mixers
* Instruments with Pickups - Into Your Amp or the Mixer
* Great for Karaoke and Harmonica Mics!
* Any Device with 1/4 in. Connectors

How It Works:
* Precisely detects feedback frequency
* Places super-narrow (1/10 octave) digital filter directly on feedback
* Sets filter just deep enough to remove feedback

What You Get:
* More gain... for the first time you'll have to turn down the monitors!
* Increased clarity and intelligibility - narrow filters get the feedback and leave your sound untouched
* Automatic feedback control - in setup and during the performance
* Targeted feedback control - aim the FBX where you need it most!

The FBX-SOLO is the perfect solution for wireless mics - you'll be able to move freely without worrying about feedback. Patch it in your monitors and they'll be so loud you may have to turn them down. Get the volume you want with your acoustic/electric instrument or harmonica mic and keep that rich tone. And the built-in noise gate provides the control you need in multi-mic locations like conference rooms and courthouses. Wherever you have an open microphone, the FBX is the most effective and least expensive way to make a dramatic improvement in your sound system. zZounds is an authorized dealer of Sabine products.

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

** Note: Inputs may be balanced or unbalanced. For maximum output capability, outputs must be balanced (XLR). If either side of an input is grounded, the peak output and dynamic range will be reduced by 6 dB.

*** Tests performed using an Audio Precision System One model 322 or equal.
