Matrix Audio MS-1 Flagship Music Streamer - DAC

PCM Resampling & DSD Conversion

You can let the built-in asynchronous upsampling and DSD conversion engine process all the audio data in digital stage. With asynchronous resampling and interpolation operations, jitters will be isolated and details will be improved. The DSD converter transforms all playing audio into DSD, enhancing sound density. The processing engine features adjustable PCM or DSD conversion configurations, allowing you to experience the sound differences under different settings.

IIS-LVDS Digital Output

MS-1 also works as a high-level audio transport that can output all playing audio as high-resolution signals through IIS-LVDS port. Including audio signals from analog input and phono input. Which enables you to connect to other DACs to achieve different listening experiences.

MS-1 has two pairs of line inputs and one pair of phono input. With XLR and RCA line inputs allowing you to integrate any device with analog output into the digital audio system. The built-in phono preamplifier supports both MM and MC modes, enabling direct connection to a vinyl turntable. All analog audio inputs are converted to digital audio through high-precision ADC, aggregated into the digital processing unit and applied PCM filters. These signals are also allowed to output from the IIS-LVDS port.

Preamplifier & Dual Balanced Output

MS-1 Pre features a built-in preamplifier and a precision resistor array volume control. The preamplifier is composed of multi-stage op-amps, which has a +10dB gain and can output audio signals up to 16VRMS. It compatible with power amplifiers or active speakers directly. Providing excellent channel consistency and distortion characteristics even at low volumes. Additionally, MS-1 Pre offers a pair of fixed-level XLR line outputs, which can be used simultaneously with the pre-out. Enables you to connect it to other recording and monitoring devices.

Matrix Audio's first product based on AKM D/A solution, featuring dual AK4191 and AK4499 flagship D/A chipsets. Each chipset works in parallel in mono mode. The left and right channel PCB assemblies are mounted at two sides of the device separately, to form a completely dual mono design. Aiming to a precise signal reproduction and outstanding dynamic range, you can catch every micro details of sound, deeply restoring the essence of music.

Precision Resistor Volume Control

The volume control is a critical factor affecting audio quality, ensuring lossless attenuation and consistent volume levels between channels is the prerequisite for good sound. MS-1 Pre has a built-in preamplifier which uses voltage-divider volume control by resistor array. Four high-quality volume control units composed of 64 precision resistors with 1‰ 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.

Clocks are the cornerstone of digital audio systems. Unlike previous Matrix Audio products, the MS-1 is equipped with a high-performance DPLL clock synthesis circuit. The ultra-low phase noise reference clock works with the DPLL circuit generates an clock signal with jitter as low as 45fs in real-time, providing a reference for the entire digital audio circuitry. If you have a higher-precision 10MHz external clock, you can connect it to the clock input port to enhance the performance of the internal audio clock.

Expandable SFP Fiber Optic Network Port

In order to isolate high-frequency interference from switches and front-end network devices, we have added an SFP interface, enabling the music streamer to connect to the local network via fiber optic cables. With the electrical isolation properties of fiber optic transmission, the electrical connection between the front-end switch and the music streamer can be completely disconnected, ensuring a purer sound. Of course, we also retain the Ethernet port for convenient connection without altering your network structure.

NVMe SSD Slot

In order to avoid the annoying experience of frequently plugging and unplugging USB drives, we reserved an NVMe SSD slot on the bottom of the chassis of MS-1. You can install an high-speed SSD as internal storage, avoid of using a 2.5" or 3.5" HDD, completely eliminating the impact of vibration and noise of HDD on sound quality. Music resources stored on the SSD can be maintained through network sharing, or copy the music files from the external storage to the internal storage through MA Remote App.
