Bluetooth operating instructions**
Connection:
Step 1: Switch the input source in the SETTING MENU or press the Bluetooth button of the remote;
Step 2: Turn on the Bluetooth function of the mobile phone, search for “SMSL SU-9 PRO”, and tap to pairing. When the mobile phone displays “connected”, it has been successfully connected.

Re-connection:

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 SU-9 PRO 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

• SU-9 PRO’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 SU-9 PRO 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

DSD FILTER
There are 4 kinds of digital filtering in total. It’s the way that the digital operation means the clutter outside the audio Filter out, respectively

• 47kHz Cutoff
• 50kHz Cutoff
• 60kHz Cutoff
• 70kHz Cutoff

SOUND COLOR
There are 9 sound color settings in SU-9 PRO.

• Rich1、 Rich2、 Rich3
• Tube1、 Tube2、 Tube3
• Crystal1、 Crystal2、 Crystal3

This setting is using the DSP of ES9038PRO,to make some different sound color, all of these settings will not change the frequency res pones curve. When set to “Standard”, this setting will be bypassed.

PRE MODE
Volume control enable or disable.

• VARIABLE: IN this mode, volume can be adjust by remote controller, and make SU-9 PRO a pre-amplifier.
• FIXED: IN this mode, volume is fixed on max output level, and the SU-9 PRO will ignore the volume operations.

FN KEY FOR

• BLUETOOTH
• PHASE

DPLL

• MIN ~ MAX
  (A total of 15 kinds, the default is 7 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 inter rusted. Increase this value can avoid the sound interruption! Especially when using TV as signal source!

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

• In this page, press and hold the button of the knob, the system will reset all settings, including Bluetooth pairing status.
