Say Goodbye to Live Mic Bleed

Mixing live shows is a rollercoaster ride, where things constantly change. Mic bleed could be causing feedback that prevents you from turning up the PA. Or you may constantly need to mute background noise when a singer isn’t singing. Or maybe you need excellent isolation with a live multitrack recording.

PSE is the answer to these and other live sound challenges. It’s an easy-to-use, optimized expander that solves most issues instantly—and allows you to handle even the toughest bleed problems.

End Live Sound Mixing Nightmares

Which vocal mic has bleed from the drums?! Why is feedback kicking in? Where’s all that hum coming from? Why do I have to keep turning mics down?!? Run your audio through PSE, so you can stop running around solving problems—and concentrate on creative mixing.

Precision Sound Matters

PSE keeps the music’s integrity, by sending unwanted sounds smoothly into silence when a performer pauses. With precision expansion optimized for melodic sources like vocals, guitars, strings and more, you can forget about troublesome noise gates. Just set Threshold and Range: PSE will smoothly attenuate anything below that threshold, by the range level you’ve set.

Pump Up the Volume

Mic bleed is a breeding ground for feedback, so you need to keep turning mics down due to squeals, or to spend your time manually muting channels. Not with PSE: stop the bleeding automatically, and you’ve dramatically improved gain-before-feedback.

A Side Order of Sidechain

To solve really stubborn bleed problems or inconsistent stage volumes, sidechaining with external inputs, filtering, and ducking increase PSE’s effectiveness even further—while still retaining ease of use.
