Furthermore, the adjustable gain functionality allows for seamless integration with a wide range of preamplifiers and sources. At the core of the MA-1’s design lies an independent dual-channel architecture, each channel boasting its own robust 1250VA power supply. This massive power reserve ensures that the amplifier can effortlessly handle even the most demanding transients and dynamic swings, delivering an uncompromised and captivating listening experience. The MA-1 also showcases Matrix Audio’s attention to detail and commitment to excellence in every aspect of its design. Its H-shaped structure provides a solid and sturdy foundation, while the silent cooling system ensures whisper-quiet operation, allowing you to immerse yourself in the music without distractions. With its cutting-edge technologies, exceptional versatility, and unwavering commitment to sonic purity, the Matrix Audio MA-1 power amplifier stands as a testament to the brand’s pursuit of audio perfection. As the centerpiece of the M series, it ushers in a new era of Matrix Design language, serving as a precursor to the future evolution of Matrix Audio products and elevating the listening experience to new heights.

Matrix Design for a New Generation of Power Amplifier Assessing audio products through the lens of “listening” and “looking” has always been Matrix Audio’s consistent philosophy. From conception to design, each step embodies a passion for music and a quest for aesthetics. The MA-1 stands as Matrix Audio’s inaugural Class AB power amplifier. Its industrial design embodies simplicity, featuring a hexahedral shape adorned with hundreds of circular perforations of varying sizes and depths arranged in an array. These resemble rhythmic beats dancing and emerging on the surface. The power amplifier stands as the backbone of the entire audio system, necessitating comprehensive performance that excels in both dynamic and nuanced scenarios. It should surge powerfully during intense moments and delicately reveal subtleties with finesse. The MA-1 is tailored for the MS-1 and MP-1, providing precise matching and tuning to ensure that the entire system delivers exceptional audio performance and operational experience. Multi-triode In Parallel Push-pull Output To reduce output impedance, we utilized 10 ONSEMI high-power transistors per channel in a push-pull amplification circuit, operating at a high bias current. This design results in a static power consumption of up to 300W. The amplifier delivers 250W per channel at an 8-ohm load and 450W per channel at a 4-ohm load. Stereo Mode: Each amplification unit within one amplifier handles the left and right channels separately, ensuring precise reproduction of every note on the stereo stage. Bridged Mode: By combining two power amplifiers, you can unleash greater power for your music, effortlessly driving speakers with demanding power requirements or low sensitivity. Mono Mode: Two amplifiers work for each channel, aiming for extreme sound quality. This mode provides an advanced driving setup for high-end separate speakers or bi-wiring speakers, unlocking their full potential. Adjustable Gain: The amplifier features two gain levels. The normal gain is +30dB, which can be attenuated to +24dB. This allows for optimal setup with different pre-amps and speakers. Independent transformers for the left and right channels enable a fully independent dual-channel design, providing a total power supply of 1250VA. The main power operates at ±80V. Each channel is equipped with 14 parallel-connected 6,800µF capacitors, forming a main power supply filtering capacitor matrix. This results in a total capacitance of 190,000µF across both channels. Using multiple capacitors in parallel, instead of a single capacitor with the same total capacity, reduces equivalent internal resistance and ensures greater flexibility in handling large current outputs. A New and Unique Craftsmanship The H-shaped structure, a distinctive design by Matrix Audio for the M series products, is the result of two years of continuous optimization and refinement, taking into account mechanics, circuit layout, and exterior aesthetics. A 20mm CNC aluminum plate serves as the support structure for the entire device after undergoing dozens of procedures, forming the core of the H-shaped design. All components are mounted on this aluminum plate, with the entire weight supported by heavy-duty feet attached to the main beam, ensuring solidity and stability. Once the panels are installed, multiple isolated cavities are formed around the main beam. Different circuit modules are strategically placed in each cavity, effectively minimizing interference between them. The circuit modules for the left and right channels are symmetrically arranged on both sides, creating a balanced and visually appealing design. Silent Cooling The MCU continuously samples the temperature using two sensors on the main heatsink, ensuring constant monitoring. When the temperature exceeds the preset threshold, a 7.4″ ultra-quiet fan automatically activates, dynamically adjusting its speed. The fan operates so quietly that it is barely noticeable even at low volumes or when the device is muted. Additionally, the isolated duct design ensures no electronic components are within the airflow path, preventing dust accumulation during long-term operation. The ingenious industrial design is an integral part of Matrix Audio’s products, showcasing the brand-new Matrix design language through dots, lines, and surfaces. Each component undergoes meticulous CNC machining and multiple surface treatments, resulting in an exquisite and comfortable matte texture. This craftsmanship not only enhances the operational experience but also imparts a distinctive and elegant temperament to the product. The MA-1 delivers rich and exquisite sound, immersing you in its depths. It’s more than just an auditory pleasure; it’s a heartfelt experience. Every note and chord tells a story, making you fall in love with the sound. Every detail of the M series reflects Matrix Audio’s pursuit of excellence. Everything you hear, see, and touch represents the culmination of the Matrix Audio team’s continuous trials, meticulous refinements, and careful calibrations. Matrix Audio perseveres tirelessly, striving to enhance beauty and make the sound even more captivating.
