Matrix Audio MP-1 Reference Preamplifier

Description

The new Matrix Audio MP-1 Preamplifier is a key component in the chain. It must process the input music accurately, endowing it with rich tones and textures, allowing you to hear the sound of music, see the face of music, and feel the soul of music. It is also the sculptor of music.

The MP-1 features a fully differential transistor input stage circuit design features extremely low noise and excellent linearity. The output stage is designed as a high-bias current pure Class A output, free from crossover distortion. It operates under a low-noise power supply of up to 60V to achieve extraordinary dynamic range. The output DC servo circuit keeps the output midpoint offset within 1mV, no coupling capacitors involving ensures a flatter frequency response, allowing the original sound to be presented as it is.

The main amplification portion of the MP-1 consists of four independent fully balanced amplification units. Each channel has two amplification units working together, responsible for amplifying the in-phase and inverted signals. Even in RCA input mode, the signal will be converted into a bipolar signal for amplification, effectively suppressing common-mode noise and improving dynamic performance.

The new Matrix Audio MP-1 features 1 pair of RCA outputs and 2 pairs of XLR outputs, capable of output simultaneously or separately. When outputting separately, the volume for each output can be adjusted individually, making it easier to achieve comfortable volume levels when connecting multiple power amplifiers and different speakers. When both XLR outputs are used at the same time, it's possible to connect four power amplifiers to drive the mid-high range drivers and low-range drivers of the speakers separately, to achieve a bi-amping mode.

The new MP-1 features a voltage-divider volume control by resistor array. Four high-quality volume control units composed of 64 precision resistors with 0.001 accuracy and 32 fully sealed reed relays which are switched rapidly by the MCU. This control method not only minimizes any impact on sound quality but also ensures excellent consistency between the two channels. The operation noise of the reed relays is almost inaudible even when changing volume continuously.

The new MP-1 features two 60W high-power square copper wire toroidal transformers, providing power separately to the volume control unit of the left and right channels and the main amplification unit, achieving independent dual-channel design from the source. Compared to traditional toroidal transformers with circular cross-section wire, square copper wire has a larger conductor surface, higher current capacity, and lower resistance, resulting in better transient response and richer low frequencies. Paired with the M-Lytic AG series filter capacitors from MUNDORF, it adds a silky smoothness and mellow to the sound.

The new MP-1 delivers warm and delicate sound, with powerful low frequencies without sacrificing the details in the highs. Whether you are listening to chamber music or symphony orchestra, everything is presented perfectly under the control of the MP-1. 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.
