Matrix Audio MD-1

Purist Design Meets State-of-the-Art Audio Technology

With the MD-1 and MD-1P models, Matrix Audio introduces a new generation of hi-fi power amplifiers, designed with a clear focus on integration and efficiency. Each unit combines a music streamer, digital signal processing, and powerful amplifiers into a single device—replacing several components typically found in traditional hi-fi systems. Building a high-quality audio system has never been easier: one amplifier, one pair of passive speakers—that's all it takes for audiophile-grade music enjoyment.

Powerful and Efficient

Both models deliver impressive output power: the MD-1 provides 2×150 W into 8 ohms, while the MD-1P offers 2×300 W into 8 ohms. They can effortlessly drive both bookshelf and floorstanding speakers. Thanks to highly efficient amplifier technology, this is achieved with reduced heat generation and low energy consumption. Advanced PWM signal processing minimizes distortion, ensuring precise, detailed, and distortion-free sound reproduction—tailored to the demands of discerning audiophiles.

Lossless Speaker Outputs with A/B Switching

The gold-plated, pure copper speaker terminals have been custom-designed by Matrix Audio, offering exceptionally low contact resistance and secure connections. The MD-1P features two speaker zones that can be switched via IR remote—ideal for A/B comparisons or different listening zones.

Digital Precision: FPGA & Femtosecond Clocking

In the digital signal path, both models use a combination of two femtosecond-accurate clocks for 44.1/48 kHz-based sampling rates and an FPGA with proprietary clock management and jitter reduction logic. The result: ultra-low phase deviation and a highly spatial, “airy” sound signature.

Reference-Class Analog Volume Control

A 256-step digitally controlled analog volume control replaces mechanical potentiometers, eliminating their typical wear issues. Volume can be adjusted from -80 dB to +12 dB in fine 0.5 dB increments. An intelligent algorithm ensures phase coherence between channels, even at low volumes. An additional 12-step balance control allows for precise room and speaker positioning adjustments

Outputs for Preamp and Subwoofer

The units feature pre-out and subwoofer outputs, with levels controlled in sync with the main volume. A low-pass filter at 150 Hz enables seamless integration of active subwoofers. The MD-1P includes two subwoofer outputs, making it especially suitable for large listening spaces. The trigger interface allows automatic power control of connected subwoofers.

Integrated Phono Preamplifier

Vinyl enthusiasts will appreciate the dedicated MM phono input with RIAA equalization. The specially tuned preamp allows direct connection of a turntable, making it possible to set up a full analog system without extra equipment.

Flexible Line Inputs with Bypass Mode

With both balanced XLR and unbalanced RCA inputs, compatibility with almost all analog source devices is ensured—from studio gear to classic CD players. In bypass mode, the MD-1 and MD-1P function as pure power amplifiers, making them ideal for use in AV multi-channel systems.

Extensive Digital Connectivity

Up to four optical and coaxial digital inputs allow the connection of a wide range of sources—from set-top boxes and gaming consoles to Blu-ray players. HDMI ARC makes it easy to integrate a TV. The USB audio input enables lossless playback of music files from a computer.

HD Bluetooth for Wireless Hi-Res Streaming

Both devices support Bluetooth 5.0, including high-resolution codecs such as aptX, aptX HD, AAC, LDAC, and SBC, with transmission rates of up to 96 kHz. This enables wireless hi-fi music streaming—perfect for spontaneous listening.

Connected via Cable or Wi-Fi 6

For maximum transmission stability, a Gigabit Ethernet port is available. Alternatively, Wi-Fi 6 provides a robust wireless connection for high-resolution PCM and DSD file streaming—ideal for discreet home installations without network cables.

Digital Archiving via CD Drive

A standout feature: connect a USB CD drive, and CDs can be digitally archived directly using the MA Remote App. This combines the analog CD experience with the convenience of digital library management—including the option to permanently archive physical media.

Conclusion

With the MD-1 and MD-1P, Matrix Audio introduces two meticulously designed devices that combine streaming convenience, amplifier power, and audiophile attention to detail in a minimalist form factor. Whether as the centerpiece of a purist hi-fi setup, part of an AV system, or for analog media lovers—these amplifiers set new standards in integration, sound quality, and user-friendliness.
