How to use

The new remote control use:

remote Totaldac d1 remote control

Available keys, to select one Totaldac equipment among two or three using a single remote control:
--number "7": selects the remote control receiver of the d1-streamer only
--number "8": selects the remote control receiver of the reclocker only
--number "9": selects the remote control receiver of the DAC only
--number "6": selects the remote control receiver of all Totaldac products

Available menus:
GAIN (from firmware V9.0): the digital gain be set to NORMAL (0dB, clipping is impossible) or +12dB (clipping is possible).
The +12dB gain can be useful to be able to listen to tracks with low recording level on a system with a low global gain and when the DAC volume is used. Set to "NORMAL" by default.
EARTH: when "CONNECTED" is selected the signal ground is connected to the earth. When "UNCONNECTED" is selected the signal ground and the earth are isolated. Choose the best configuration to get the best silence from your amplifier or the best sound when listening to music.
DISPLAY: when "ON" is selected the display is always switched on, when "OFF" is selected the display is switched off 10 seconds after the last remote control action.
TREBLE FIR: When "ON" is selected the non-oversampling treble loss is compensated to get a flat frequency response. When "OFF" is selected the DAC is a pure NOS (non-oversampling) DAC with some treble attenuation.

Note: always leave batteries in the remote control.

The bass boost option:
The bass boost option allows to sum a bass channel to the main channel. The bass channel, called CH1, is the output of a low pass filter.
The bass channel is summed to the main channel, called CH3.
Before the summation is made an attenuation is applied to CH1 and CH3.

Next table shows the recommended attenuation so set (from the remote control) for CH1 and CH3 according to the target bass boost level and with the guarantee to avoid the saturation or the digital signal:

bass boost table

The filter frequency is adjustable with 1Hz step.
If for example the frequency is set to 100Hz it means that the boost has its main effect from 0Hz up to 100Hz and then the effect slowly diminishes.

USB AUDIO2 driver:
No driver installations are necessary for Windows10, iOS and Linux.
Under older Windows a driver installation is necessary. A specific driver will be provided by e-mail.

Here are the settings recommended for Roon (and quite similar for other softwares):

Totaldac streamer user's guide:
The d1-streamer-mk2 and DACs with streamer option have a specific user's guide that you can download here:

The previous remote control or d1-core remote control:


The remote control functions are:
-VOL+ key (indication N8): increases main volume control
-VOL- key (indication N5): decreases main volume control
-"on/off" key (indication N11): switches the DAC ON or OFF, the audio circuits are maintained warm in OFF mode
-"mute" key (indication N9): mutes all analog outputs
-Numerical keyboard, selects among 4 digital inputs:
--number "1": selects input1 RCA
--number "2": selects input2 XLR
--number "3": selects input3 optical
--number "4": selects input4 USB
-"0" and "-/--" keys: goes to previous or next menu to adjust the phase polarity, earth connection, display on/off and for the digital filters the cut-off frequencies, the digital delays, the relative attenuation of each way...
-PROG+ key (indication N4): increases the current parameter in the active menu
-PROG- key (indication N6): increases the current parameter in the active menu
-"teletext" key (indication N2): stores to memory all current settings
