X30 uses a large OLED display for real-time status and function operations. The following figure shows the status of the main screen. Input channel External clock display 2. Input Channel Selection: X30 has a total of 7 input channels. In the main screen state,every time the small gear key is pressed,the current input channel can be selected in the order of COAX----AES---- OPT----USB----STREAMER----IIS(G) ----IIS(M*). *** Note: The IIS(G) is GUSTARD format and can not adjust; The IIS(M*) is an adjustable IIS port. USB DSD 22.4M FIXED Sampling rate Encoding format Volume 3. Volume Adjustment : When the screen is in main screen state,the "+" and "-" buttons can directly adjust the analog volume attenuation function of the passive preamplifier of the X30. The volume can be attenuated from 00dB to -90dB,with a total of -90dB attenuation. When the volume is at 00dB,press the "+" button again to enter the fixed output mode (pass-through,bypassing the volume part),and the volume position displays FIXED. When the volume displays FIXED,press the "-" button reduces the volume to exit FIXED first,and then adjust the volume. -4- Settings Menu: On the main screen, long press the small gear button to enter the settings menu (hereinafter referred to as the menu button). In this state, the menu button can sequentially switch the menu items to be modified. "+" and "-" buttons are used to adjust the currently selected menu options. When the screen is in the settings menu, long press the menu button again to return to the main screen. MENU The menu directory tree structure is as follows: 1.

VIVID GENTLE COMPOSITE VIVID filter is similar to the FAST roll-off type of traditional digital filter, but the ringing characteristics are better, with very small pre-ringing and fast convergence post-ringing.Itcan getveryrealand accuratedetails,soundfieldand soundrestoration. When listening to most music styles, we strongly recommend that you use this digital filter. GENTLE is similar to the SLOW roll-off type of traditional digital filter, with a soft listening experience. COMPOSITE is a hybrid digital filter, which is between the two and has a very good listening experience. 2. DSD FILTER (DSD Digital Filter Adjustment): The DSD filter has 4 built-in bandwidth options: 47K 50K 60K 70K 3. NOS MODE (No Oversampling Filter Mode): When enabled, the PCM signal will bypass the oversampling filter and go directly to ES9039SPRO. At the same time, ES9039SPRO also turns off the internal PCM oversampling digital filter. DISABLE ENABLE *** When enabled, there may be a slight clicking sound when the playback data format switches between PCM and DSD. -6- Menu Functions: 4. REF CLOCK (Reference Clock Selection): GUSTARD-K2, low-noise clock synthesizer. With ultra-low phase noise, its synthesized clock achieves ultra-low jitter performance of femtosecond level, while being able to directly pass the near-end performance of the reference clock. Due to its high-precision divider, the frequency accuracy of the synthesized audio clock reaches ppb level. Thanks to this, the master clock of the digital processing circuit built into the X30 is also provided by the K2 high-precision lock synthesizer. REF CLOCK can choose: INTERNAL EXT. 10Mhz Internal reference, using the built-in OCXO Selecting an external 10M reference source it is recommended to connect to GUSTARD C16 or C18 reference 10M master clocks In the external clock state( EXT. 10Mhz Options), After exiting the menu. when the external 10M is correctly locked. the main screen will display the word EXT If the external clock is lost, or the external clock is forgotten to be turned on, or the 10Mhz frequency deviation of the external clock output is greater than +-150ppm, " EXT ERR " will be displayed and flash. -7- Menu Functions: 5 . IIS MODE (IIS Pinout Mode Selection): X30 has 2 IIS input: 1. IIS(G) is GUSTARD pinout and cannot be adjusted. When playing DSD, a DSD FLAG needs to provide by the front end. 2. IIS(M*) is an adjustable Pinout mode. It can automatically detect PCM and DSD encoding so there is no need a DSD FLAG signal. The Pinout of IIS(G) (GUSTARD MODE) is as follows: *** When the IIS(G) input plays back DSD, the front end needs to provide DSD FLAG ***MODE1 is compatible with the GUSTARD mode. If you are connecting to a GUSTARD front end such as U12, U16, U18, S16, S26, etc., you can match them with MODE1, when the former works in the GUSTARD output mode. All MODE1-MODE4 Pinouts refer to the following figure: MODE1 (GUSTARD) MODE2 DATA/DSDL+ DATA/DSDL- GND LRCK/DSDR+ LRCK/DSDR- GND NC NC GND GND 1 3 5 7 9 11 13 15 17 19 2 4 6 8 10 12 14 16 18 GND BCLK/DSDCLK+ BCLK/DSDCLKGND MCLK+ MCLKNC NC NC DATA/DSDRDATA/DSDR+ GND LRCK/DSDLLRCK/DSDL+ GND NC NC GND GND 1 3 5 7 9 11 13 15 17 19 2 4 6 8 10 12 14 16 18 GND BCLK/DSDCLK+ BCLK/DSDCLKGND MCLK+ MCLKNC NC NC MODE1 (GUSTARD) DATA/DSDL+ DATA/DSDL- GND LRCK/DSDR+ LRCK/DSDR- GND NC P/D MODE(0:PCM 1:DSD) GND GND 1 32 54 76 98 11 10 13 12 15 14 17 16 19 18 GND BCLK/DSDCLK+ BCLK/DSDCLKGND MCLK+ MCLKNC NC NC IIS OVER HDMI(Socket view) Please do not connect to the usual HDMl, this is not really HDMl IIS OVER HDMI(Socket view) Please do not connect to the usual HDMl, this is not really HDMl MODE3 DATA/DSDR+ DATA/DSDR- GND LRCK/DSDL+ LRCK/DSDL- GND NC NC GND GND 1 32 54 76 98 11 10 13 12 15 14 17 16 19 18 GND BCLK/DSDCLK+ BCLK/DSDCLKGND MCLK+ MCLKNC NC NC IIS OVER HDMI(Socket view) Please do not connect to the usual HDMl, this is not really HDMl -8- IIS OVER HDMI(Socket view) Please do not connect to the usual HDMl, this is not really HDMl MODE4 DATA/DSDLDATA/DSDL+ GND LRCK/DSDRLRCK/DSDR+ GND NC NC GND GND 1 32 54 76 98 11 10 13 12 15 14 17 16 19 18 GND BCLK/DSDCLK+ BCLK/DSDCLKGND MCLK+ MCLKNC NC NC IIS OVER HDMI(Socket view) Please do not connect to the usual HDMl, this is not really HDMl Menu Functions: 6. PHASE (Phase Setting): This function has two options: NON-inverted RCA normal phase output--XLR American standard Inverted RCA inverse phase output--XLR Japan/European standard) When NON-inverted, the RCA output of X30 is normal phase, and the XLR balanced output is American standard polarity output, that is - 1 ground, 2 hot, 3 cold. When Inverted, not only the RCA output is reverse phase output, but the XLR balanced output will be Japanese/European standard polarity output, that is - 1 ground, 2 cold, 3 hot. 7. TRIGGER CH. (Linkage trigger start channel selection) The X30 can be triggered by an external 12V linkage signal and automatically turn on from standby mode. When 30 is working, it is switched to the input channel of this setting by the 12V trigger linkage signal. If the 12V trigger input signal stops or turns down to 0V, it will automatically enter the standby state Note: ***1 This time the X30 is turned on by 12V trigger, not manually turned on ***2 After this trigger, the X30 is in the trigger channel set ***3 After this trigger, the X30 input channel has not been manually switched The above 3 conditions are met and the X30 will automatically enter standby to execute LAST the input channel that was in use before entering standby last time COAX -- AES -- OPT -- USB -- STREAMER -- IIS(G) -- IIS For the remaining channels above, whichever one you choose, when the 12V trigger signal comes, it will enter that channel and turn on the X30. -9- Menu Functions: 8. TRIGGER VOL. (Link Trigger Boot Volume Selection): X30 can be triggered by an external 12V linkage signal, and can be turned on automatically from standby mode and set to this volume. Or when X30 is working, it is switched to the set volume by the 12V trigger linkage signal. This option is used to set the volume of the X30 output after the trigger power on. LAST The volume used before entering standby last time FIXED Output at fixed full volume -20dB Output at a volume attenuated to -20dB -30dB Output at a volume attenuated to -30dB -40dB Output at a volume attenuated to -40dB 9. DISPLAY (Screen Brightness Settings): AUTO AUTO OFF ALL AUTO OFF DISPLAY Automatically reduce brightness Automatically turn off the screen Automatically turn off the screen display Long-term high-brightness use of OLED screens can easily cause screen burn-in, ghosting, etc. Therefore, it is designed to always. automatically reduce the brightness, or manually select automatic screen off, which can also reduce interference. -10- Infrared Remote Control: * Enter control DAC mode by long pressing the DAC key 3-5 s 1 Standby: switch between standby and working.
