How do I fix my audio feedback?
One of the most commonly asked questions in professional audio is “What microphone can I use that doesn’t cause feedback?” The answer to the question is, of course, that no such microphone exists. Feedback results from a combination of many factors, including loudspeaker placement, microphone placement, the frequency response of both devices, and room acoustics.
In this article, we’ll look at a few different techniques that can help keep feedback under control.
QSC CMX Series Amplifiers – Proven, Reliable Power Plants
The QSC CMX series – including the CMX300V, CMX500V, CMX800V, and the CMX2000V – offers an economical and rugged power amplifier solution designed to meet the needs of system integrators. It is based upon the proven, rock-solid, reliable performance found in the award winning RMX Series. The amplifiers are designed to deliver true and accurate sound performance and feature high-current toroidal transformers and filtering to ensure generous energy reserves allowing the amplifiers to effortlessly handle high-level transients, even when driving abusive 2-ohm speaker loads. The CMX series is the perfect amplifier for gymnasiums, retail stores, houses of worship, club venues, and more.
Protecting Your PA Sound System
The show you’re mixing is fantastic, hands-down. The kick drum and bass are grooving perfectly in their respective pockets, the guitar is piercing through with definition, and the clarity of the vocals are pristine. The energy is overwhelming, the crowd is thumping, and because everything is sounding great, the band is rocking out as hard as they can. The front man, dancing like a madman, moves right in front of the monitor and lets out his tri-county famous Rock ‘n Roll Wail. Then it happens – a sharp blast of ear-bleedingly deafening feedback, followed by the muffled noise of stage volume. Your mains have just been blown, and the show is ruined.
But the worst part is, you could have prevented this situation entirely, with just a few tweaks to your PA Sound System.
Subwoofers, Crossovers, and the ever-important “Do I need them?”
Yorkville YX18S
Purchasing a subwoofer for your PA sound system is a decision that requires well-informed thought. Subwoofers are not necessary for every system, and even if you decide to get one, it must fulfill all of your requirements. If you’re reading this article, either you’ve outgrown your setup and are looking to add some extra “boom” to your less-than-adequate system, or you’re getting a new sound system and are deciding whether or not you should spend the extra cash from the get-go. We’ll discuss both of these scenarios (and more) after the jump.

What’s in a Sound System?
The part of a sound system that is most obvious to casual listeners who are not involved in the sound business is probably the speaker system that produces the sound output that we hear directly. The speaker system is actually only the last in a chain of several devices that amplify, route, and process the sound signal.
