d1-integral music server/DAC

NEW / DSD READY

The d1-integral is a digital source gathering in the same equipment a Totaldac DAC/preamp and a music server. The music server allows to listen to all your music from a single storage and with the best possible sound.

Totaldac d1-single front
The d1-integral has analog outputs with an embedded volume control and it is DSD-ready.
It is controlled from an Ipad.
The music storage is external to allow a maximum of flexibility. It can use ethernet discs (NAS), USB discs.
The music files are ripped or copied from another computer to the external discs.

Totaldac d1-integral schematics

Embedded reclocker interfaces:
-192KHz asynchronous Xmos USB, optical, RCA and AES-EBU digital inputs, selectable from a remote control.
-44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz and 192KHz, 16 to 24 bit formats supported on all inputs except 96KHz max for optical input.
-DSD (DoP standard) supported on the USB, AES-EBU and spdif inputs.
-embedded custom clock with anti-jitter FIFO memory.
-3.1Vrms max RCA and 32ohm-600ohm 3.1Vrms max headphone amplifier. The XLR connector carries only the un-balanced signal, so it is equivalent to the RCA output.
-volume control, adjusted by a remote control and an OLED display, works for all inputs, not only USB.
-phase polarity selected by remote control.
-non-oversampling DAC compensation filter activated or disactivated by remote control.
-display switched off by remote control or automatic.
-all unused inputs are completely disconnected (including the ground) to keep the optimum noise floor even when several sources are connected.
-R2R DAC technology using 0.01% Bulk Metal� Foil resistors from Vishay Foil Resistors, 100 resistors per stereo channel.
-class A discrete transistor output stage.
-external power supply to minimize the noise on the embedded preamp.
-aluminium and PMMA enclosure with massive pure copper antivibration plate.
-power consumption 18W.
-dimensions: height 110mm, width 360mm, depth 290mm.
-power supply dimensions: height 65mm, width 122mm, depth 180mm.
-weight: 6.5kg.

Computer type interfaces:
-1 ethernet port which must be connected to a Wifi/ethernet router for the control from an Ipad or a smart phone via WIFI.
It gives also access to the distant network hard discs (NAS).
Those who wish can use a computer without WIFI as a remote control via ethernet instead of a tablet via WIFI.
-1 USB2 port as an audio output to the embedded DAC.
-1 USB2 port for an optional external disc.
-1 HDMI output, not used by the pre-installed MPD player (but can be used with XBMC player, not supplied).

Technologies:
The d1-integral is composed of 5 key elements:
-the unbalanced Totaldac DAC, recognised for its sound quality, it is the base of the d1-integral.
-The 800MHz ARM based Cubox mini computer, a tiny and very low consumption computer, which generates much less electromagnetic pollution than a bigger computer.
This mini computer is completely shielded. Its software can be updated by simply changing the microSD card easily accessed on the back panel.
-A 5V ultra low noise power supply, herited from the d1-dual DAC design.
-The music player MPD running here under linux RT (real time), found to be best operating system for the sound quality after listening tests.
It is not necessary to have Linux knowledge to install and use the server, the tablet is the only interface for the user.
The music library is usually copied and organised in the NAS or in the USB disc using a Windows or MAC computer.
-The Totaldac USB cable/filter, recognised and tested in many different environments (included in the d1-integral price).
