1. Introduction

1.1 The concept

With the SHARK FBQ100 you purchased a device that combines an automatic Feedback Destroyer using the ingenious search algorithms of our FEEDBACK DESTROYERFBQ1000, a variable Delay Line (adjustable in msec, feet and meter), aULN (Ultra-Low Noise) microphone pre-amp with Phantom Power, anautomatic Noise Gate, a variable Low Cut lter and a Compressor—all in one ultra-rugged and compact case. Still, the SHARK can be operated intuitively and expanded to a multi-channel system using another four SHARKs and an optionally available 19" rack mount kit. The SHARK’s 24-bit A/D and D/A converters guarantee a precise reproduction of your program material.

High volume levels and the use of ever more sophisticated monitoring systems with a multitude of speaker cabinets have led to a greater potential risk of feedback loops in sound reinforcement systems. So far, audio engineers have been using conventional 1/3-octave equalizers to suppress unwanted feedback. However, the individual lters of such an EQ, with their relatively wide bandwidth, have quite an impac t on the sound image. With the BEHRINGER SHARK (minimum bandwidth: 1/60 of an octave) you are now free to either choose the trial and error method to suppress feedback with graphic equalizers, or to assign this task to the FBQ100, so that you can give your music your undivided attention. Using extremely narrow-bandwidth lters, the SHARKFBQ100 eliminates only unwanted feedback, without aecting yourmusic.

Please use the enclosed power supply to connect the unit to the mains. Thesupply complies with all applicable safety standards.

◊ Please note that all units must be grounded properly. For your own

safety, you should never remove any ground connectors from electrical devices or power cords or render them inoperative.

Further information can be found in chapter 3 “Installation”.

As a standard the audio inputs and outputs of the BEHRINGER SHARK FBQ100 are fully balanced. If possible, connect the unit to other devices in a balanced conguration to allow for maximum interference immunity. The automatic servo function detects unbalanced connections and compensates the level dierence automatically (6dB correction).

1.2 Before you begin

Your SHARK was carefully packed in the factory and the packaging is designed to protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the carton and its contents for any signs of physical damage, which may have occurred during transit.

◊ If the unit is damaged, please do not return it to BEHRINGER, but notify

your dealer and the shipping company immediately, otherwise claims for damage or replacement may not be granted. Shipping claims must be made by the consignee.

The optionally available rack mount kit allows you to mount your BEHRINGER SHARK in a standard 19" rack, together with another four SHARKs. The rack mount kit requires 2U of rack space.

Be sure that there is enough air space around the unit for cooling and please do not place the SHARK on high-temperature devices such as power amps, etc. to avoid overheating.

(1) The CLIP LEVEL METER shows you whether or not the digital circuitry is

driven correctly. Any corrections can be made with the CLIP LEVEL control

(2). Be sure that the CLIP LED won’t light up.

(2) The CLIP LEVEL control lets you adapt the internal gain optimally to the

digital circuitry. If gain is too high (CLIP LED lights up), raise the CLIP LEVEL value by turning the control to the right (and vice versa). Thus, you can shift the operating level upwards/downwards.

◊ The CLIP LEVEL control does not affect the input/output levels,

but adapts the audio signal as optimally as possible to the threshold of the digital circuitry.

(3) These ve LEDs symbolize the units of the parameters that can be adjusted

on the display (4).

(4) The 4-digit DISPLAY reads the absolute values of the adjusted parameters.

(5) The FB-D FILTER STATUS LEDs display the status of each of the 12 individual

lters. The SHARK uses four dierent lter modes:

• Disabled lters (which can be re-enabled with the ACTIVE button). When a

lter is o, its LED is not lit.

• Free lters which automatically search for feedback frequencies and whose

activity is shown by a ashing LED.

• Set lters which can be recongured as free (searching) lters, when all

lters are currently in use.

• Permanently set lters which must be RESET to be recongured as

freelters.

Once a lter has been set, its LED lights up.
