What is feedback suppression
and how can it help your performances?

Squuueeeeeeaaaaccchh! You know it in an instant: that piercing, ear-melting shriek blaring out of your loudspeakers. It’s feedback, and it’s a showstopper—in more ways than one.

Feedback, the high-pitched wail generated when a signal loop builds between a sound system’s audio input (here, a microphone) and amplified output (speaker), can happen anytime, anywhere. Feedback dangers lurk all around you: Common offenders include singers cupping mics, presenters on wireless mics wandering into danger zones onstage, incorrect placement of floor monitors, even fluctuations in air temperature and humidity. And, feedback isn’t just an annoying noise; it can cause irreparable damage your loudspeakers—and your ears.

There are many ways to reduce the potential for feedback, including introducing noise gates, EQing problem frequencies, lowering gain, switching to a more directional microphone, or simply moving your mic closer to the sound source or out of a loudspeaker’s line of fire. To maximize volume before feedback, live sound engineers “ring out” P.A. systems by methodically bringing up system levels until feedback occurs, EQing out problem frequencies and repeating the process until the system is optimized.

Feedback can occur at any frequency, and is often caused by a confluence of factors. If you’re not a professional audio engineer, it’s easy to find yourself chasing a solution through endless trial and error—or worse yet, leaving your show up to chance. Luckily, there’s a safety net. Automatic Feedback Suppression, and for more control, Advanced Feedback Suppression™ (AFS), a dbx patented algorithm is available in several dbx products, which uses sophisticated filters and algorithms to take the guesswork out of feedback management.

Automatic Feedback Suppression works like this: The algorithm monitors incoming audio for signs of feedback; when it detects feedback behavior, it places a narrow notch filter at each frequency that feeds back, reducing the gain of that frequency. Ultra-precise, 1/80-octave filters carve out offending frequencies with pinpoint precision, preserving as much of the surrounding frequency spectrum as possible, which in turn preserves overall sound quality. This process takes just milliseconds, and is complete before the human ear can detect anything amiss.

$display.stripTags($content.custom.BlogStack1Title) — A feedback loop is created when sound is captured by a microphone, amplified, played through a loudspeaker, picked up again by the microphone, then re-amplified in a continuous loop, generating a howling, screeching sound.

Automatic Feedback Suppression is easy to use: Just set your desired level of suppression and it works automatically. Choose your level of control, from the totally preset press of a button Automatic Feedback Suppression feature in products like JBL IRX Series and JBL EON700 Series loudspeakers to the advanced (AFS®) functions in processors such as the dbx AFS2 Advanced Feedback Suppression processor and DriveRack PA2, which let you opt for a setup wizard or dig into finer parameter control, whether you’re ringing out your system or protecting your system during your show.

Automatic Feedback Suppression technology makes managing feedback fast and easy. With a little practice and thorough sound checks, you’ll be a pro at stopping feedback in its tracks, so you can keep the focus where it belongs: on your performance.

A Sound Decision:
Choosing the Right Studio Monitor -
by Sarah Jones You’ve spent long hours in the studio carefully fine-tuning your mix, obsessing over every detail until you’re satisfied with your sonic masterpiece. But when you listen to your finished product on a new system—your car, your home stereo, headphones—you’re shocked to discover that it sounds absolutely nothing like that mix you worked so hard to perfect.

How does DAB+ work? DAB stands for Digital Audio Broadcasting. So basically, it is just a digitally transmitted sound. This is different to FM, for example, which is sound that is transmitted via radio waves, and you can adjust it to suit your location. The range of DAB is much wider, and because it is digitally transmitted, the quality is also better. Because it does not use radio waves, there is no noise. This means that even in the remotest corner of the country, you will have crystal-clear sound.
