Remote control
- Install 2 x AAA batteries as instructed.
- When using the remote control, point it toward the remote control signal receiver on the main unit from a distance of 5 m (16 ft) or less. Do not place obstructions between the main unit and the remote control.
- The remote control might not work if the remote control signal receiver on the unit is exposed to direct sunlight or bright light. If this occurs, try moving the unit. Beware that the use of this remote control could cause the unintentional operation of other devices that can be controlled by infra.

About MQA
MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. The DO200 includes MQA technology, which enables you to playback MQA audio files and streams, delivering the sound of the original master recording. Visit How it works https://www.mqa.co.uk/how-it-works for more information.
MQA files playback
- DO200 has only USB, optical, coaxial, and AES interfaces, and supports MQA decoding.
- DO200’s MQA playback does not require additional software. You can use foobar2000 or Audirvana for MQA playback as it supports ASIO or WASAPI audio output. When playing MQA audio, it is suggested to adjust the volume of the computer to the maximum for the best audio output.
- The DO200 LED next to the MQA logo glows green or blue to indicate that the unit is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. It glows blue to indicate it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.
- When playing an MQA file, the sampling rate of the original master recording is displayed.

SPDIF MODE
This setting is only valid for optical/coaxial and AES interfaces that use
SPDIF protocol;
NORMAL MODE
NORMAL mode, only use the digital receiver chip (DIR) to process the SPDIF
signal, used in most occasions, in this mode supports MQA renderer and DoP
playback, but at this time due to the limitation of the ES9068AS chip, it
cannot display that the current playing is DoP, and only 176.4kHz input can be
displayed. This is normal, and the internal will still decode DoP and output
normal audio.
PROCESSOR MODE
PROCESSOR mode, in this mode DO200, will use the XMOS processor to process the
optical/coaxial signal so that it can have the more powerful computing power
and can handle various complex tasks including MQA, and DoP, in this mode,
Play DoP audio, and the DSD icon will be displayed correctly on the display.
Note: do not switch this mode frequently, try to restart the machine
after switching this mode, otherwise it may cause output noise.
SOUND COLOR
There are 9 sound color settings in DO200.
- Rich1、 Rich2、 Rich3
- Tube1、 Tube2、 Tube3
- Crystal1、 Crystal2、 Crystal3
This setting is using the DSP of ES9068AS, to make some different sound colors, all of these settings will not change the frequency response curve. When set to “Standard”, this setting will be bypassed.
PRE MODE
Volume control enables or disables.
- Vol Fixed: In this mode, volume is fixed on the max output level, and the DO200 will ignore the volume operations.
- Vol Variable: In this mode, volume can be adjusted, and make DO200 a pre-amplifier.

DPLL
MIN ~ MAX
(A total of 15 kinds, the default is 5 kinds. The larger the number is, the
stronger the range to adapt to jitter, and the smaller the number, the better
the performance against clock jitter.) This DPLL setting is a special function
of ESS series products. It can adjust the internal DPLL digital phase-locked
loop circuit Bandwidth so that the chip achieves a balance between anti-clock
jitter and input tolerance.
Its function:
- When the clock stability of the input signal is good, this value can be reduced, so that the clock performance of the system is better;
- When the clock stability of the input signal is not good, the sound may be interrupted. Increasing this value can avoid sound interruption! Especially when using TV as a signal source!
I2S MODE
- NORMAL
- INVERTED
Note: This option is used to match different I2S interface standards, please check the interface definition of the signal source before use
DSD CHANNEL
- DSDL=PCM DATA (The DSD left channel using the PCM DATA pin)
- DSDL=PCM LRCK (The DSD left channel using the PCM LRCK pin)
Note: When using the I2S input to stream DSD audio, if you find that the left and right channels are incorrect, you can use this option to correct it.
DSD FLAG
- DSD FLAG=PIN15
- DSD FLAG=PIN14
DIMMER
- 5 second ~ 60 second
(The range is 5 seconds-60 seconds. After setting, the screen will automatically go off within this time, and the screen will re-light up if you operate the remote control or the knob at any time.)
BRIGHTNESS
LEVEL 1 ~ LEVEL 6
RESET
- During Bluetooth input, long-press the middle button of the knob, and the system will only reset the Bluetooth pairing status;
- During other input, long press the middle button of the knob, and the system will clear all settings, including Bluetooth.
