Evaluating audio products from the dimensions of "listening" and "looking" has always been our consistent philosophy. From concept to design, every step contains the love for music and the pursuit of beauty. MA-1 is Matrix Audio's first Class AB power amplifier. Its industrial design showcases our concept of simplicity. With hundreds of circular perforations of varying sizes and depths arranged in an array on the simple hexahedron, resembling rhythmic beats dancing and emerging on the surface.

Complementing MS-1 and MP-1
The power amplifier serves as the backbone of the entire audio system, requiring comprehensive performance that excels both in dynamic and nuanced scenarios. It should surge powerfully during intense moments and delicately reveal subtleties with finesse. The MA-1 is born for the MS-1 and MP-1, offering precise matching and tuning to ensure that the entire system delivers exceptional audio performance and operational experience.

Multi-triode In Parallel Push-Pull Output
In order to reduce the output impedance, we applied 10 ONSEMI high-power transistors in each channel to compose a push-pull amplification circuitry, which operating at a high bias current state. The static power consumption is up to 300W. At an 8-ohm load, it provides 250W output power per channel, and 450W output power per channel at a 4-ohm load.

Adjustable Gain
The amplifier has two gain levels. The normal gain is +30dB, which can be attenuated to +24dB. Allowing you to setup the amplifier with different pre-amps and speakers.
