Choirflex is a digital signal processor that intelligently learns your venue’s acoustical environment and provides processed choir audio that results in much greater gain before feedback and increased clarity.
Greater Acoustical Gain
With up to 10 dB gain-before-feedback, easily get your choir on top of the mix.
Adapts To Your Environment
Listens and adjusts according to your venue's acoustics.
Increased Clarity & Stability
Speech intelligibility of every section in the choir, from bass to soprano.
Maintains Natural Tonality
Clean, natural tone of your choir's vocal blend.
Choirflex has given us fantastic gain before feedback. It’s the loudest I’ve ever been able to get our choir. It’s really important both for our live and online experiences that our choir is clearly present in the mix.
With Choirflex we’ve been able to lower, or a lot of times get rid of our vocal backing tracks completely because of the fullness we are now getting in our live mix.

Providing sound reinforcement for choir can be one of the most difficult tasks in live audio. Achieving sufficient gain-before-feedback, minimizing stage-to-microphone leakage, and getting the choir “on top of the mix” with clarity are classic challenges that prove difficult to overcome.
Choir reinforcement typically makes use of condenser microphones covering large groups, and is therefore subject to excessive room reverberation, PA system effects, and feedback. The common result is a deteriorated choir mix that is prone to electroacoustic feedback and suffers from poor intelligibility.
Good microphone placement and console equalization can help, but are quite often not enough, and these “solutions” often deteriorate musicality and overall tonality.
Choirflex is a proprietary, adaptive digital audio processor designed to increase the clarity and stability of choir mixes and greatly reduce feedback while maintaining the natural sonic qualities of the choir.
In combination with its use in sound reinforcement, Choirflex is equally effective for sending processed choir sounds to broadcast and recording mixes.
