PSI Audio AVAA C214: Active Bass Trap - Single

Precision Low-Frequency Control for the Perfect Room Response

Transform your listening environment with the PSI Audio AVAA C214 Active Bass Trap - a groundbreaking solution for precise low-frequency control. Designed for studios, mastering suites, and audiophile spaces, the AVAA C214 eliminates standing waves and low-end build-up without any calibration or software. With its plug-and-play design and adaptive analogue processing, it functions as a virtual acoustic absorber, targeting frequencies between 15–160 Hz to create an exceptionally accurate and controlled acoustic environment.

Active Acoustic Innovation
Unlike passive absorbers that rely on bulk and material density, the AVAA C214 uses active acoustic technology to control low frequencies in real time. It continuously measures air pressure variations via an internal microphone and compensates by generating an inverse acoustic signal, effectively reducing resonances without altering the room’s natural sound. This unique PSI Audio innovation offers the absorption performance of a large, perfectly tuned bass trap - in a compact and elegant enclosure.

Precision Room Tuning Without Calibration
The AVAA C214 is completely self-contained and requires no software, tuning, or digital interface. Simply place one or more units in the room, and the system begins working immediately. By automatically adapting to acoustic pressure changes, it removes the need for complex measurement setups and ensures consistent, natural results across all listening conditions. Whether for mixing, mastering, or critical listening, the AVAA enables you to hear your audio exactly as it was intended.

Studio-Grade Design and Performance
Crafted in Switzerland by PSI Audio, the AVAA C214 combines audiophile-grade analogue circuitry with precision engineering. Each unit is hand-calibrated and matched for optimal performance. Its robust construction, sleek modern design, and silent operation make it suitable for any professional or home studio environment. The C214 not only improves frequency accuracy but also enhances the clarity, depth, and detail of your overall soundstage.
