This series includes the music streamer MS-1, the preamplifier MP-1 and the power amplifier MA-1, forming a complete flagship system of Matrix Audio that presents our understanding of Hi-Fi audio. The M series is the first lineup to adopt the new Matrix Design language, serving as a precursor to the future evolution of Matrix Audio products.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eMatrix design philosophy\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eEvaluating 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. The 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.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eDesigned to complement the system\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe 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 integration.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eMulti-triode in parallel push-pull output\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eIn order to reduce the output impedance, we applied 10 ONSEMI high-power transistors in each channel to compose a push-pull amplification circuitry, 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. Lower output impedance supports improved speaker control, especially during demanding passages.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eStereo mode\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eEach amplification unit in one amplifier handles left and right channels separately.

The normal gain is +30dB, which can be attenuated to +24dB. Allowing you to pair the amplifier with different pre-amplifiers and speakers while maintaining appropriate signal levels and low noise.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eSurging power supply design\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eIndependent transformers for the left and right channels enable a fully independent dual-channel design, with a total power supply of 1250VA. The main power is ±80V. Each channel features 14 parallel-connected 6,800µF capacitors, forming the main power supply filtering capacitor matrix. The total capacity of capacitors for both channels reaches 190,000µF. Compared to a single capacitor with the same capacity, multiple capacitors in parallel feature lower equivalent internal resistance, ensuring greater flexibility in handling large current outputs.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eH-shaped structural craftsmanship\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe H-shaped structure is a unique design created by Matrix Audio for the M series products, born from two years of continuous optimization and improvement considering various aspects such as mechanical relationships, circuit layout, and exterior appearance. The 20mm CNC aluminum plate becomes the support structure of the entire device after dozens of procedures, serving as the core of the H-shaped structure. All components are mounted on the aluminum plate, and the entire weight is supported by heavy-duty feet installed on the main beam, making it solid and stable. After the panels are installed, multiple isolated cavities are formed with the main beam. Different circuit modules are properly placed in each cavity, effectively reducing interference between circuit modules. The circuit modules for the left and right channels are symmetrically arranged on both sides, creating a balanced visual impression.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eSilent cooling system\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe MCU continuously samples the temperature with two sensors on the main heatsink, constantly monitoring the temperature. When the temperature exceeds the preset value, a 7.4 inch ultra-quiet fan runs automatically and adjusts the fan speed dynamically. You will hardly notice the fan is working even when the device is at low volume or muted. The isolated duct design ensures that there are no electronic components inside the airflow path, preventing dust accumulation from long-term operation.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eElegant and refined design language\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe industrial design expresses the Matrix Design language through dots, lines and surfaces.
