How to use

Remote control use:

remote

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

New available keys from software version V3.5, to select one Totaldac equipment among two or three using a single remote control:
--number "7": selects the remote control receiver of the server 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:
PHASE: can invert the absolute phase of the signal, 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.
DSD --> PCM: for the reclocker and d1-server, set ON or OFF the DSD (DoP) to PCM 176KHz/24 conversion.
Set ON if the DAC which follows the reclocker/server is not DSD compatible.
Set OFF if the DAC which follows the reclocker/server is DSD compatible. The reclocker/server volume control must be set to 0dB to allow to pass the DSD in DoP format.
BASS BW: the optional high pass filter adjustment.

For the active crossovers the other menus are:
DELAY CH1: the delay applied to the bass channel, unit is centimetre. The max delay is 3.4m up to 96KHz and 1.7m at 192KHz.
DELAY CH2: the delay applied to the midrange channel, unit is centimetre. The max delay is 3.4m up to 96KHz and 1.7m at 192KHz.
DELAY CH3: the delay applied to the treble channel, unit is centimetre. The max delay is 3.4m up to 96KHz and 1.7m at 192KHz.
ATTEN CH1: the attenuation of the bass channel, unit is dB, step is 0.2dB.
ATTEN CH2: the attenuation of the midrange channel, unit is dB, step is 0.2dB.
ATTEN CH3: the attenuation of the treble channel, unit is dB, step is 0.2dB.
LPF CH1: low pass filter CH1, the frequency of the bass channel low pass filter.
LPF CH1 slope: the slope of the bass channel low pass filter, adjustable to 6dB/oct, 12dB/oct or 18dB/oct.
HPF CH2: high pass filter CH2, the frequency of the midrange channel high pass filter.
HPF CH2 slope: the slope of the midrange channel high pass filter, adjustable to 6dB/oct, 12dB/oct or 18dB/oct.
LPF CH2: low pass filter CH2, the frequency of the midrange channel low pass filter.
LPF CH2 slope: the slope of the midrange channel low pass filter, adjustable to 6dB/oct, 12dB/oct or 18dB/oct.
HPF CH3: high pass filter CH3, the frequency of the treble channel high pass filter.
HPF CH3 slope: the slope of the treble channel high pass filter, adjustable to 6dB/oct, 12dB/oct or 18dB/oct.
CH3 FILTER: allows to switch ON or OFF the treble channel high pass filter, to pass quickly from an active crossover to a simple DAC (with headphone amplifier).


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.
When you switch OFF the bass boost it is better to set "atten CH3" to -1.6dB to automatically avoid any saturation.

USB input:
No driver installations are necessary for a MAC and Linux.
Under Windows a driver installation is necessary. A specific driver will be provided by e-mail. Please wait until you have received the DAC before installing the Windows driver.
During the installation the software will ask you to plug the USB device. So you will have to switch ON the DAC, push the button "4" on the remote control to select the USB input and plug the USB cable. Then follow the on screen instructions.
