Setting the clocking sync mode
You can change the clocking sync mode for the current digital input. The sync mode setting is
stored separately for each input.
1. Press the Menu button.
2. Select UNIT SETTINGS > SYNC MODE.
3. Press the Menu button to change the sync mode.
If the unit can't find a word clock that is synchronous with the data on the current
AES or SPDIF input, it defaults to audio sync. The incorrect clock icon
Changing the mapper
The mapper controls how data is presented to the Ring DAC™ core. Bartók DAC includes three
mapper designs.
1. Press the Menu button.
2. Select UNIT SETTINGS > MAPPER.

Audio. The unit extracts the clock from the data stream connected to the input and locks
to it. Recommended for sources that do not have a suitable Word Clock input. Cannot be
selected for USB or network inputs.
Master. The unit uses its own internal clock and outputs a clock to the source device.
This is the normal mode for the USB and network inputs when a Master Clock is not
available. When using AES or SPDIF inputs in Master Mode, the unit outputs a clock
signal at the WORD CLOCK OUT connection, which must be connected to the Word
Clock input of the source device.
Word Clock 1-2 Auto. The unit automatically locks to the appropriate clock connected to
WORD CLOCK 1 and WORD CLOCK 2. Recommended for systems with a Master
Clock in a computer audio system, as the data rate of the music may keep changing.
• Connect the WORD CLOCK 1 input to a Master Clock output set to 44.1, 88.2, or
176.4 kHz.
• Connect the WORD CLOCK 2 input to a Master Clock output set to 48, 96, or
192 kHz.
Word Clock In 1. The unit locks to an external clock connected to WORD CLOCK 1.
Word Clock In 2. The unit locks to an external clock connected to WORD CLOCK 2.
Mapper 1. The new default mapper design, which drives the Ring DAC™ core at
either 5.644 or 6.14 MHz.
Mapper 2. The classic mapper design, used on version 1 dCS products. This mapper
design drives the Ring DAC™ core at either 2.822 or 3.07 MHz.
Mapper 3. An alternative mapper design, which drives the Ring DAC™ core at either
5.644 or 6.14 MHz.
