PSI Audio

What PSI Audio does

PSI Audio is the commercial brand of Relec SA, a Swiss audio equipment manufacturer founded in 1977 and headquartered in Yverdon-les-Bains. The company designs and handcrafts professional reference studio monitors, subwoofers, and active bass traps for sound engineers in recording, mixing, mastering, broadcast, and immersive audio applications. The product portfolio spans the A14-M through A226-MAIN monitor series, Sub A125-M, Sub A225-M, and A326 D-REX subwoofers, A214-M and A215-M mastering/center monitors, the AVAA C214 (digital) and AVAA C20 (analog) active bass traps, the Héritage3 residential speaker, and supporting accessories such as gig bags, the LFE module, R&B router/bass management, and metal grills and brackets.

Core technology centers on fully analog active monitor design, deliberately avoiding DSP. The proprietary CPR (Compensated Phase Response) system uses all-pass filters to maintain constant group delay and accurate sound placement across multi-way speakers and surround configurations. Amplification uses Class G/H topologies with multiple power supply rails to reduce average power consumption and heat. The AVAA (Active Velocity Acoustic Absorber) platform physically reduces room modes between 15–160 Hz, with published claims of 30–50% RT60 reduction and 3 AVAA units outperforming 6 six-inch-thick passive traps. Each product is individually tested and calibrated in an in-house anechoic chamber.

The business model is hardware sales with a one-time/perpetual pricing structure, no disclosed prices, and 100% advance payment terms. Distribution runs through a tiered global channel: official distributors holding stock and providing service, authorized dealers with demonstration pairs and first-level support, and end-user ambassadors hosting listening sessions, supplemented by direct factory sales from Switzerland for uncovered markets. The Custom Pro program adds an enterprise sales motion targeting large studios, broadcasters, and immersive audio installations, delivered through certified Custom Pro Partners handling system design and installation. Customer segments include professional recording and mastering studios, broadcast and post-production, immersive audio (Dolby Atmos, 360 RA, Auro-3D), film and video post-production, and a smaller hi-fi/audiophile segment. PSI Audio holds no external institutional funding and operates as a privately held, founder-led (Alain Roux) Swiss corporation.
