MATRIX Mini-i AD1955 V2 USB DAC SPDIF - XLR - RCA - Headphones

MATRIX AD1955 Mini-i DAC (Version 2011)

DAC with USB inputs - BNC (SPDIF) - Toslink - AES / EBU
RCA - XLR Variable Outputs - Headphone Amplifier + Remote Control Aluminum

This unit is a Digital - Analog Preamplifier XLR and Headphone Amplifier.

Despite its average size it is equipped with all existing digital inputs, two types of analog outputs, a headphone amplifier.
It even has an SPDIF output to convert the signal to the digital inputs.
This may be useful, for example, for a DTS or AC3 signal arriving in optics and needing to be decoded externally by a DTS decoder.

The XLR and RCA outputs are variable through the volume knob which is an endless potentiometer. (-90dB to -0dB)
The sound level is recorded when turned off, so this unit can really be used as a digital preamp and placed at the top of your Hi-Fi system.
The inputs are selected by pressing the same button.

The decoder scheme is symmetrical, it uses two converters based on the AD1955 Analog Device already used on very high-end devices.
Thee receiver is an AK4113 with low Jitter and chip amplification headphone TPA6120.
