Description
Matrix Audio MP-1: Analog Class A preamplifier for flexible stereo systems
The Matrix Audio MP-1 is an analog Class A preamplifier for stereo systems. It consolidates the connected music sources, handles volume control, and offers flexible connection options for various power amplifier configurations.
Key features at a glance
- Source switching: Six analog inputs with separately adjustable level matching.
- Signal processing: Fully balanced design with a Class A output stage, even when using the RCA inputs.
- Volume: Resistor network with reed relays for precise volume steps and channel matching.
- Output selection: Two XLR output pairs and one RCA output pair can be used individually or in the designated combinations.
- Ease of use: Touch controls, RM4C remote control, and configurable power-on volume.
Switch sources, adjust levels
Three stereo input pairs via XLR and RCA are available for DACs, network players, CD players, and other analog sources. Different output levels can be matched separately for each input, so that less readjustment is required when switching between connected devices.
The MP-1 processes analog line signals. Digital sources require a suitable D/A converter; a turntable is connected via a suitable phono preamplifier. USB-C is used exclusively for firmware updates and is not a USB audio input.
Balanced amplification and precise volume
Four independent, fully balanced amplifier units handle signal processing. Even signals from the RCA inputs are converted into a balanced signal for further amplification. The output stage operates in Class A with a high quiescent current.
The volume control uses a precise resistor network and sealed reed relays instead of a conventional potentiometer. The design is intended to provide a uniform level for both channels and offers one hundred volume steps.
The channel-separated power supply uses two toroidal transformers and linear power supplies. This supports the consistently separated design of the two audio channels without requiring additional power supply enclosures.
A preamplifier for various power amplifier configurations
Two balanced XLR output pairs and one RCA output pair enable several connection configurations. XLR A, XLR B, both XLR pairs together, RCA, or all outputs simultaneously can be selected. This allows, for example, different power amplifiers to remain connected without having to swap the signal cables.
With the "Independent volume" setting enabled, the MP-1 stores separate volume levels for the various output configurations. When operating together, the outputs reproduce the same selected stereo program; separate music sources per output are therefore not intended.
The two XLR output pairs also enable suitable bi-amping configurations. This requires suitable power amplifiers and speakers with correspondingly separate connections. Trigger in and out allow the coupled switching on and off of compatible devices.
Operation and placement
Touch fields on the front handle source selection, output selection, volume, and muting. The included RM4C infrared remote control complements operation from the listening position; its programmable buttons can be assigned to a specific source or volume level.
The display and touch fields can be adjusted in brightness. An automatic dimmer reduces the lighting when the device is not in use. For the next start, the MP-1 can either adopt the last used level or start at a set volume.
The enclosure is based on an H-shaped support structure made from a CNC-machined aluminum plate. Separate chambers spatially arrange the circuit modules; the matte surface and perforated pattern characterize the design of the M Series.
Suitability and important notes
Who is the preamplifier suitable for?
- For stereo systems with a separate power amplifier and multiple analog sources.
- For music listeners who want to use various power amplifier configurations.
- For systems whose sources deliver significantly different output levels.
Important notes
- To drive passive speakers, a power amplifier is additionally required.
- Leave more than 5 cm of free space around the device for ventilation and keep the ventilation openings unobstructed.
Positioning in the M Series
The MP-1 forms a coordinated system of the M Series together with the MS-1 music streamer and the MA-1 power amplifier. Through their uniform design and the combination of devices designed to work together, the components complement each other to form a complete Hi-Fi system.
Conclusion
The MP-1 is interesting for a stereo system where multiple analog sources and separate power amplifiers permanently have their place. Individual level matching, precise volume control, and flexible output selection make it easier to adapt to the existing equipment, while operation on the device and from the listening position remains clear and straightforward.
