Singxer SDA-6 DAC User Handbook
1. Thank you for choosing Singxer product. Please check the appearance and all its
accessories carefully once you have Singxer SDA-6 in hand.
2. Before you supply AC mains power to the SDA-6, please check your power supply AC
voltage. There are 2 kinds of input AC voltage selectable according to the switch label
110V and 220V. 110V is for input AC voltage 100-120VAC and 200-240V is for input AC
voltage 230VAC. Attention: wrong AC voltage input will damage the SDA-6. Once power
cable is connected, turn on the power switch and you will see the power indicator turned
on.
3. Connect the SDA-6 to a computer or digital player via USB Type A to Type B cable. (Note:
USB’s 5V power supply can not be open circuited); For WINDOWS system, it requires the
SDA-6 driver to be installed, although the SDA-6 can be used without driver under the
latest version of WINDOWS 10, it is recommended to use the driver we provided; Linux or
MAC system has built-in driver included for the SDA-6, there is no need to install driver on
the latest version of Linux or MAC system.
4. Once the SDA-6 is recognized by your computer or digital player, please ensure “Singxer
SDA-6” is selected as the output device in your computer system or digital player setting;
While playing music, the SDA-6 will display the corresponding sample rate.
5. Most music players require proper setting for DSD playback. If you see the DSD sample
rate isn’t displayed correctly, most likely it is due to the incorrect player settings. Please
refer to our other support documents for any detail.
6. The front panel of the SDA-6 displays visual information via an OLED screen on the middle
side (no touch function); There are 5 aspects of information, which are digital filters
(D-filter), PLL option, Clock option, current input source and sample rate.
7. Digital Filters: There are 6 digital filters in PCM mode,
SHARP/SLOW/SHORT
SHARP/SHORT SLOW/NOS/ LOW-DISPERSION; In DSD mode, the SDA-6 uses only NOS
(no oversampling) as the digital filter.
8. PLL option: the setting switchs at the bottom of the machine, and the eighth switch
controlled the PLL. When it is ON, the PLL is turned on, and when it is OFF, PLL is turned
off. The PLL option is valid when optical, coaxial, AES, and BNC are input. PLL LOCK is
displayed when the PLL is locked normally.
PLL is turned on by factory default.
9. Clock options: select the clock source is the internal clock or the external clock.
In USB mode, it supports 10M clock and the level is 0.5V-3.3V VPP. The input impedance is
adjustable, and the adjustment switch is the eighth switch at the bottom of the chassis. It is
50 ohms when it is ON, and 75 ohms when it is OFF.
In the coaxial mode (optical, coaxial, AES, BNC input), it supported WCK (sampling rate,
WCLK) , the level is TTL, and the input impedance is standard 75 ohms (not controlled by
switch 8 at this time).
When EXT CLOCK LOCK is displayed, the external clock is used.
When PLL LOCK and EXT CLOCK LOCK are displayed at the same time, the external clock
is preferred.
I2S input adopts the bypass mode, and does not support PLL and external clock.
