-192KHz asynchronous Xmos USB, optical, RCA and AES-EBU digital inputs, selected 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.
-as an option, DSD (DoP standard) supported on the USB, AES-EBU and spdif inputs.
-USB input compatible with Jplay in 24 bit "extreme hibernate" mode.
-embedded custom clock with anti-jitter FIFO memory.
-3.1Vrms max RCA, 6.2Vrms max XLR analog output and 32ohm-600ohm 3.1Vrms max headphone amplifier.
-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% VAR Bulk Metal® Foil resistors Vishay Foil Resistors, 200 resistors per stereo channel.
-dual DAC option included, using 2 DACs per channel for a 100% balanced DAC. Upgrades the XLR output only. A special XLR to RCA is available as an optional extra to get the dual DAC sound to an amplifier with RCA inputs.
-class A discrete transistor output stage for the d1-dual DAC.
-possibility to connect a headphone with an impedance higher than 45ohm and with xlr connectors directly to the balanced XLR output of the DAC. A way to get 6.2Vrms and get 4 times more power. Also allows to listen directly a headphone with the dual DAC option, a Abyss, Sennheiser HD 800, an Audeze or a AKG K701 for example.
-external power supply to minimize the noise on the embedded preamp.
-aluminium and PMMA enclosure with massive pure copper antivibration plate.
-power consumption 21W.
-DAC dimensions: height 110mm, width 360mm, depth 290mm.
-power supply dimensions: height 65mm, width 122mm, depth 180mm.
-weight: 6.5kg.
Available options:
-DSD (DoP) option.
-silver massive aluminium front panel.
-115V power option.
-BNC coaxial digital input instead of RCA.
-D2-dual, 69 bit 2 way active crossover including a digital preamp for the main volume control and also for the relative level between bass and treble. The bass channel uses two RCA connectors for stereo without dual DAC option or in mono with dual DAC option. The mid-high channel uses RCA and xlr (balanced) connectors, with dual DAC option. The crossover slope can be 6dB/oct, 12dB/oct or 18dB/oct. All parameters, crossover frequency, filter slope, relative volume, main volume, relative digital delay... can be controlled from the remote while listening to music. The subwoofer output can be mono-balanced on demand instead of stereo.
With the d2-dual with DSD option the digital delays can't be used.
-2, 3, 4 way active crossover or more, with or without dual DAC option, by associating several DAC boxes.
-pair of XLR to RCA adaptor in an external box, special "dual DAC", 3.1Vrms output.
-USB cable with high performance filter for a noticable sound quality improvement.
-Bass boost.
