Matrix "cube" ASRC DAC

Introduction

All the great features enable Matrix CUBE to help you explore every small detail in the music and provide you a tactile sensation of its sound performance. It has ultra-high resolution and signal-to-noise ratio. We believe this product will fully meet your requirements of high-quality Hi-Fi experience.

Features

·         The award winning top shelf 24 bit/ 192 kHz D/A converting unit - Wolfson WM8740

·         High-end digital sampling rate increase processing chip - TI SRC4382

·         ASRC (Asynchronous Sample Rate Converter) - the technique of separating the internal and external clock and re-sampling, which effectively reduces the timing jitter generated by the former sources and transmission lines

·         A professional digital receiver chip of ultra-low jitter and a high-precision clock independent system

·         USB, optical, coaxial digital inputs and a coaxial output that supports multiple channel pass-through

·         Up to 24 bit/192 kHz digital signal input via s/pdif input channels

·         Digital signals can be up-sampled to 174.6 KHz /192KHz and put out through digital channel

·         The internal headphone amp unit can easily drive any headphones of 300 ohms and below

·         Headphone amplifier can work independently when it is connected to external signal source

·         Professional stereo OP-Amp, OPA2134/LM833, are used to provide you with the best signal playback effect

·         Multi-stage stabilized voltage supply unit

ASRC Sampling Rate

When the ASRC switch on the front panel is turned ON, the CUBE will resample the input signal to 176.4/192 kHz according to an high-precision internal clock, keeping away the original clock coming with the signal, which effectively reduces the timing jitter generated by the former sources and transmission lines.

When ASRC is OFF, the CUBE will convert D/A according to the original input sampling rate. The frequency of ASRC output depends on the sampling rate of the input signal.

If the sampling rate of the input signal is 44.1 kHz or its integral multiples, the ASRC output sampling rate will be 176.4 kHz; when it is 48kHz or integral multiples, the ASRC output sampling rate will be 192 kHz.

Headphone Output

The high-quality standard 1/4”stereo headphone plug-jack on the front panel can drive any headphone of 300 ohms and below, which makes it very convenient to use your headphone. Use the volume control knob on the front panel to adjust the volume.

When the “Amplifier” switch on the front panel is switched to the position of Internal, the internal amplifier circuit will be connected to the internal output of CUBE and directly monitor the output signal.

When it is switched to External, the amp unit will be connected to the external input and monitor external audio signal via the analog input ports. Meanwhile, the DAC unit of the CUBE works unaffectedly.

Coaxial Digital Output

The CUBE possesses a coaxial digital output. The output state depends on the condition of the output channel. This channel directly outputs current digital signals. When the ASRC on the front panel is switched off, the CUBE will output the original code such as AC-3, DTS and so on. When the ASRC is turned on, the CUBE will increase the sampling rate to 176.4/192 KHz. It is also very convenient to connect it with other digital audio equipment or AC-3, DTS decoders.

USB Driver

The CUBE’s USB interface works without any extra driver under Microsoft Windows 2000/XP/Vista/7, Linux, Mac OS X. However it does not support AC-3, DTS stream signal transmission unless an extra driver is installed. With the extra driver, Xear™ Virtual 3D processing and 10-band equalizer is supported.
