Matrix Audio MP-1 – Reference Class-A Preamplifier for uncompromising musical enjoyment

Pure Class-A preamplifier for audiophile demands

The Matrix Audio MP-1 is an uncompromisingly developed high-end Class-A preamplifier that combines maximum sonic purity, exceptional musicality, and supreme precision. Its fully balanced Class-A circuit operates without crossover distortion and delivers an impressively natural, spatial, and detailed performance. Whether as the heart of a high-end stereo system or in an uncompromising reference chain, the MP-1 sets new standards for discerning music lovers.

Fully balanced signal path for maximum sound quality

Internally, the MP-1 utilizes four fully balanced amplifier modules that process the positive and negative signal components of each channel separately. Even analog RCA signals are internally converted to a balanced signal path, effectively reducing interference and significantly improving dynamics and spatiality. The fully discrete Class-A output stage ensures an exceptionally open, finely resolved, and authentic sound reproduction.

Precise volume control without sound loss

Instead of conventional potentiometers, Matrix Audio relies on a high-quality resistor ladder volume control with 64 precision resistors and 32 hermetically sealed reed relays. This elaborate construction ensures perfect channel matching, minimal signal loss, and consistently high sound quality—even at very low volumes. In this way, dynamics, fine detail, and naturalness are fully preserved at all times.

Flexible connection options for high-quality HiFi systems

With three RCA and three balanced XLR inputs, the MP-1 integrates easily into sophisticated high-end systems. Level attenuation and compensation can be individually configured for each input, so that volume differences between various source devices are automatically balanced. This allows for particularly convenient and seamless switching between all audio sources.

Versatile outputs for stereo and bi-amping systems

The MP-1 features one RCA output and two balanced XLR outputs. These can be operated together or independently and can have their volume adjusted individually. This makes the preamplifier ideal for complex HiFi configurations with multiple power amplifiers, active speakers, or high-quality bi-amping systems.

Powerful linear power supply for maximum signal purity

A high-quality power supply forms the foundation of any audiophile performance. That is why Matrix Audio uses two specially developed 60-watt toroidal transformers with rectangular copper wire, which supply the amplifier section and volume control separately. Together with audiophile Mundorf M-Lytic® AG filter capacitors, this creates an exceptionally stable, low-noise power supply with high dynamics and excellent transient response.

High-quality workmanship and convenient operation

The solid CNC-milled aluminum housing with an innovative H-structure reduces resonance and reliably protects the sensitive electronics from electromagnetic interference (EMI/RFI). All functions can be conveniently controlled via the high-quality remote control, while the integrated 12-volt triggers allow for automatic power on/off in conjunction with other components.

Perfect complement to the Matrix Audio M-Series

The Matrix Audio MP-1 harmonizes perfectly with the Matrix Audio MS-1 network player as well as the Matrix Audio MA-1 stereo power amplifier. Together, they form a perfectly matched high-end system that combines state-of-the-art audio technology, uncompromising sound quality, and elegant design at the highest level.
