Remote control
- Install 2 x AAA batteries as instructions.
- When using the remote control, point it toward the remote con-trol 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 use of this remote control could cause the unin-tentional 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 MKII
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 MKII has only USB, optical, coaxial and AES interfaces, supports MQA decoding.
- DO200 MKII’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 MKII LED next to 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.
and the Sound Wave Device are registered trade marks of MQA Limited.© 2016

SOUND COLOR
There are 9 sound color settings in DO200 MKII.
Rich1 、 Rich2 、 Rich3
Tube1 、 Tube2 、 Tube3
Crystal1 、 Crystal2 、 Crystal3
This setting is usingthe DSP of ES9068AS,to make some different sound color,
all of these settings will not change the frequency response curve.When set to
“Standard”, this setting will be bypassed.
PRE MODE
Volume control enable or disable.
- Vol Fixed : In this mode, volume is fixed on max output level, and the DO200 MKII will ignore the volume operations.
- Vol Variable: In this mode, volume can be adjust, and make DO200 MKII 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. Increase this value can avoid the sound interruption! Especially when using TV as 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
I 2S 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 streaming DSD audio, if you find that
the left and right channels are incorrect, you can use this option to correct
it.
AUDIO PHASE
- NORMAL (2+,3-)
- INVERTED(2-,3+)
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, the system
will only reset the Bluetooth pairing status;
During other input, long press the middle button of the knob, the system will
clear all settings, including Bluetooth.
