StormAudio - PA 16 MK3

StormAudio PA 16 MK3 – Reference-Grade 16-Channel Power Amplifier

Brutal Power & Pristine Dynamics for Ambitious Home Theaters and Multi-Channel Audio Systems

• UMAC™ Class D amplification with UREC™ power supplies — up to 3 kW total capacity for effortless dynamics and ultra-clean power delivery
• 16 XLR input channels and support for single-ended or bridged (BTL) mode, offering maximum flexibility and up to 800 W per channel (bridged)
• Exceptional sound purity — very low distortion (THD+N < 0.005% @ 1 W), high signal-to-noise ratio (≈ 115 dB)
• High output power: 200 W per channel into 8 Ω (all channels driven), or 225–400 W per channel into 4 Ω, with stable delivery even under heavy load
• Robust, rack-mountable 3U chassis engineered for long-term reliability and silent operation

The StormAudio PA 16 MK3 is a high-current, multi-channel power amplifier built for those who demand reference-class performance from their home theater or multi-channel audio systems. Designed in collaboration with Pascal Audio, its UMAC™ Class D modules and four separate UREC™ power supplies ensure that even the most demanding audio passages — from thunderous film scores to intricate orchestral recordings — are rendered with authority, clarity, and total control.

Thanks to its massive power reserves and extremely low distortion floor, the PA 16 MK3 delivers sound that’s both powerful and refined: bass remains tight and controlled even during deep sub-sonic rumble, mids are solid and detailed, and high frequencies stay clean, transparent and extended. The result is a soundstage that feels expansive, accurate and true to the source, whether you're pushing a full 16-channel Dolby Atmos / DTS:X / Auro-3D setup or a simpler multi-speaker configuration.

What distinguishes the PA 16 MK3 from typical amplifiers is not only its raw power — it’s how that power is delivered. The amplifier responds instantaneously to dynamic shifts, with transient attacks reproduced cleanly and decays natural and well-controlled. This kind of performance grants music and film soundtracks the realism, weight, and emotional impact that separate audiophile-grade gear from everyday equipment.

Practical features make it installer-friendly: the 16 XLR inputs permit complex multi-channel arrangements; optional bridged mode delivers high current for low-impedance speakers or demanding subwoofers; and the rugged 3U chassis with proper ventilation keeps operation stable and quiet even under sustained heavy load. For serious home theaters or multi-room systems, the PA 16 MK3 offers both brute strength and audiophile-grade finesse.
