d1-six (transistor) DAC or DAC/server
The d1-six DAC is now the highest end one-box Totaldac DAC.
Released in 2016, it inherits from technologies developped for the d1-twelve DAC and the d1-server.
Compared to the d1-dual, the d1-six uses 6 channels of discrete R2R ladders instead of 4 ladders for the d1-dual.
The transistor output stage is also new for a higher musical performance.
The sound quality is optimum on the XLR output as well as on the headphone jack and on the direct RCA output.
This DAC can integrate the server/streamer board for a direct network use, to listen local files or for streaming use.
All d1 DACs can be upgraded to a d1-six.
-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.
-as an option, DSD (DoP standard) supported on all inputs.
-embedded custom clock with anti-jitter FIFO memory.
-2.5Vrms max RCA, 5Vrms max XLR analog output and 32ohm-600ohm 2.5Vrms 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.
-R2R DAC technology using 300 pieces of 0.01% VAR Bulk Metal® Foil resistors Vishay Foil Resistors.
-new 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 21W (25W with the server option).
-DAC dimensions: height 110mm, width 360mm, depth 290mm.
-power supply dimensions: height 65mm, width 122mm, depth 180mm.
-server/streamer option. The software is the same as the d1-server, RoonReady certified.
-DSD (DoP) option.
-silver massive aluminium front panel.
-115V power option.
-BNC coaxial digital input instead of RCA.
-2, 3, 4 way active crossover or more, by associating several DAC boxes.
The list of embedded options is on the serial number sticker on the rear panel of the DAC.
