Filter LEDs (light emitting diodes) will flash 5 times and the SETUP LED stays lit. You are now ready to set FBX filters. 2. READY The READY LED lights when the automatic FBX setup process has completed, or the READY button has been pressed. This indicates your unit is ready for operation.

SECTION two — APPLICATIONS 2.1. FBX Setup for Monitors 2.2. FBX Setup for Entire Mix 2.3. FBX Setup for Single Insert Point 2.4. FBX Setup for Insert Send & Return Filters • 12 independent digital notch filters per channel, controlled automatically from 40 Hz to 20 KHz. • Filter width: user-controllable - either 1/10 or 1/5 octave*, constant "Q" • Resolution: 1 Hz • Time required to find and eliminate feedback: 0.4 seconds, typical @ 1 KHz • Number of Dynamic vs.

SECTION FOUR — OPERATING INSTRUCTIONS 4.1. Before You Begin These instructions apply to the FBX1210. 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. In this position, the FBX can sense and eliminate feedback occurring in any channel of the mixer.

4.2. How To Operate your FBX1210 Follow these procedures to get maximum gain before feedback 1 Place equipment & make connections. a. Patch your FBX1210 into the 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. FBX Filter Control 5.1.1. Selecting Filter Width If you’re using the FBX for a music application, the standard 1/10-octave constant “Q” filter is most effective. However, in spoken word applications, such as lectures or teleconferencing, we recommend using the wider 1/5-octave filter for more robust feedback control. You may enable the 1/5-octave filters by pressing the FIFTH OCTAVE button, and the built-in LED will light.

SECTION SIX — TROUBLESHOOTING TIPS 6.0. Frequently Asked Questions Q. Can I place the FBX in the mixer’s EQ loop? A. Yes. Q. Can I place the unit in the mixer effects loop? A. Avoid this configuration. You can configure the system this way only if each effects send of each mixer channel is set so that all of the signal is routed completely through the effects loop. You cannot mix dry signal with effects signal and still control feedback. Q. The signal input LEDs do not light.

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.

7.3. Parametric Filters and FBX 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.
