PSI eliminates room modes

PSI Audio has launched the AVAA C214 active bass trap, expanding its AVAA (Active Velocity Acoustic Absorber) family with a digitally controlled variant of the original C20. The C214 is more compact and can be adjusted in its sensitivity through a remote app. It can be placed on the floor or mounted to walls or ceilings, depending on where it operates optimally. The technology eliminates room modes, acting like a black hole that hoovers up resonant modal frequencies before they are bounced back. As it does not use anti-sound, the acoustic impression is changed for the better in the entire room, not just a small sweet spot.

These individual resonances of a room are one of the biggest challenges in acoustic design. While passive absorbers require a lot of material or resonant absorbers need to be tuned to a specific frequency, the AVAA eliminates resonant frequencies between 15Hz and 160Hz as effectively as a passive absorber 45 times its size. It does not affect the direct sound from the speakers, as room correction devices do, and it does not work with anti-sound.

For the first time in the company’s history, it the C214 features a DSP chip, overcoming the challenge of reaching a latency below 0.2ms. The digital technology makes the AVAA products more flexible by virtue of its app that allows users to adjust the device’s sensitivity, plus it can be switched on and off either individually or in groups.
