5 FEEDBACK DESTROYER PRO FBQ2496 User Manual

1. Introduction

The FBQ2496 is the fastest (>0.2 sec.) and the only 96 kHz Feedback Suppressor in this market price segment. Using an ultra-fast feedback detection algorithm, it automatically and “intelligently” locates up to 20 feedback frequencies per channel and sets ex tremely narrow notch lters to “destroy” them, leaving the remainder of the signal virtually untouched.

Easy does it: with the “Set-and-Forget” default setting plus the Panic button, your FEEDBACK DESTROYER can be up and running in no time! The auto mode continuously monitors the mix, resetting programmed lters automatically, while the manual mode allows individual setting of up to 40 fully parametric lters with frequency, bandwidth and gain adjustment. Open MIDI architecture means that future software updates and exible communication with digital equipment are a no-brainer. With its various modes you can master just about any live sound situation or use it as a creative sound-shaping tool.

1.1 Before you get started

1.1.1 Shipment

Your FBQ2496 was carefully packed at the assembly plant to assure secure transport. Should the condition of the cardboard box suggest that damage may have taken place, please inspect the unit immediately and look for physical indications of damage.

◊ Damaged equipment should NEVER be sent directly to us. Please inform

the dealer from whom you acquired the unit immediately as well as the transportation company from which you took delivery. Otherwise, all claims for replacement/repair may be rendered invalid.

Fig. 2.1: How a feedback lo op is created

A feedback loop is created when a microphone signal is rst reproduced on an amplier, and is then picked up again by the same microphone (with the same phasing). Then, it is amplied and reproduced again. This feedback loop may, under certain circumstances, keep on occurring and could escalate out of control.

With P.A. applications, there are two major types of setups in which feedback canoccur:

• Front mix (also called F.O.H. = “front of house”) refers to the mix being

created when a signal from a mixing console is amplied by one or more power ampliers and is fed into loudspeakers facing the audience.

• Monitor mix refers to the mix that also originates in the mixing console but

ends up driving one or more stage monitors. Unlike FOH speakers, a stage monitor makes the music program audible to individual musicians.

◊ Please bear in mind that high volume levels can damage both your

hearing and your equipment. Be sure to always select an appropriate volume level.
