SECTION FOUR — OPERATING INSTRUCTIONS 4.1. Before You Begin These instructions apply to both the FBX1220 and the FBX2420. The 2420 is a dual-mono version of the 1220. Your FBX Feedback Exterminator will improve any sound reinforcement system. The instructions presume that you are familiar with the fundamentals of sound reinforcement. 4.1.1. Where the FBX fits in your sound system: The most common patch point is between the output of the mixer and the input of a power amp.

4.2. How To Operate your FBX1220 / FBX2420 Place equipment make connections. Follow these & procedures to get maximum gain before feedback 1 a. Patch your FBX1220 or FBX2420 into system and make all connections (refer to pages 2 and 3 for connection options). b. Place speakers and microphones in performance positions. c. Set Input and Output levels on FBX back panel (see Section 5.1.1. for details). Start with all buttons pushed in. d.

SECTION FIVE — How to use FBX Features 5.1. Input / Output Level Switches Use the two-position switches on the back panel of your FBX1220 / FBX2420 to compensate for input level or output level requirements. NOTE: For unity gain (recommended), set the channel's input & output level switches to the same setting. 5.1.1.

so the feedback clips quickly; therefore, your program will also be clipped in setup mode). Be sure the blue Ready light is on (either flashing or steady) and if it isn’t, press the READY button before your program begins. You’ll know the FBX1220 / FBX2420 is in setup mode when the SETUP button is lit. NOTE: You can manually override Setup mode if necessary. That's right -- press the Ready button! 5.3.4. Mobile vs.

SECTION seven — FBX Theory & Practice 7.1. Introduction to FBX® WHY FBX? Feedback is certainly the most pervasive challenge to the audio industry. The potential appearance of sudden, loud, out-of-control feedback is every sound engineer’s and musician’s nightmare. Unlike more subtle audio quality problems or shortcomings, feedback is embarrassingly obvious — it disturbs the performer, the audience, and the technician, and can damage equipment and just generally ruin your day.
PAGE 9
Of course, many savvy sound engineers, realizing the limitations of graphic equalizers in removing problem feedback, prefer to use a different type of equalizer, called a parametric EQ, for such applications. If you’re one such audio engineer, you’ll be comforted to know that FBX filters share much in common with parametrics. Compared to graphic filters, parametrics allow more precise adjustments — specifically, control of filter width, the amount of boost or cut, and the mid-band frequency of the filter.
