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

• Richa, Rich2, Rich3
• Tubal, Tube2, Tube3
• Crystal, Crystal2, Crystal3

This setting is using the DSP of DAC, 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.

DPLL

• MIN ~ MAX
  (A cotal of 15 kinds, the cefault is 7 kinds. The large the number is, the stronger the Ange 70 accept to jitter, and the smaller the number, the biter 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!

PS MODE

• NORMA
• REVERS£0

Note: This option is used to match different |7S interface standards, please check the interface definition of the signal source before use
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.)

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.

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-X 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.maga.co.uk/how-it-works for more information.

How to play MQA

• SU-X supports MA decoding with USB, optical fiber and coax all
• SU-X’s MQA playback does not require the use of special playback software, such as foobar2000, Adrianople’s only needs to support ASIO or WASAPI audio output, and when playing MQA audio, it is best to adjust the volume of  the computer to the maximum, so that the audio output of the computer is in the best condition.
• 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

Notes on playing MQA-CD

• Please make sure that what is being playedisagenuine AMOA-CD
• Verify that th e optical or coax. a signal output of th e CD player is an unprocessed source code
