PA3
PA3
Introducing PA3 — the next evolution of our acclaimed Class A+AB technology.
Power is the heartbeat of any audio system, and amplification sits at the core of performance. With PA3, our third-generation Class A+AB design reaches new heights, with lower distortion, a stronger power supply, and exceptional sonic purity.
Built for the channels that matter most.
In premium private cinemas, the front stage, your LCR or front five channels, carries the emotional weight and dynamic impact of every performance. PA3 was purpose-built to elevate these critical channels, bringing our flagship amplification into the P Series ecosystem with absolute authority.
A high capacitance power matrix provides immense headroom, while the fully balanced circuit design and advanced thermal management ensure pristine operation. Thanks to its ultra-high bias, PA3 runs in pure Class A for nearly all musical and cinematic content, transitioning to Class AB only under extreme output demands. The result: effortless dynamics, low distortion, and high efficiency.
PA3 delivers uncompromising power “front and center” to premium private cinemas.
