The new MA-1 power amplifier 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. 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 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. The new MA-1 power amplifier features independent 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 features lower equivalent internal resistance, ensuring greater flexibility in handling large current outputs. The new MA-1 features an MCU that continuously samples the temperature with two sensors on the main heatsink, constantly monitoring the temperature of the heatsink. When the temperature exceeds the preset value, a 7.4" ultra-quiet fan runs automatically and adjusts the fan speed dynamically. You'll hard to 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. The new MA-1 power amplifier delivers a rich and exquisite sound, immersing you in its depths. It's not just an auditory pleasure but a heartfelt exchange. Every note, every chord tells a story, making you fall in love with the sound. Every detail of the M series embodies our pursuit of excellence. Everything you hear, see and touch is the final presentation by team Matrix Audio through continuous trial and fail, meticulous polishing, and careful calibration. We persevere tirelessly, striving to make things more beautiful and the sound more captivating.
