Gustard X30 High Performance Audio DAC

Packaging List

The packaging includes:

• Mainframe
• Warranty card
• Power cord
• USB cable
• Remote control

Front Panel

The front panel features:

• Power Button: Switches between standby and working states.
• Menu display: Shows the current input channel, encoding format, and sampling rate. It also displays menu items when navigating the settings.
• Volume display: Shows the volume level from -90dB to 00dB, or 'FIXED' for volume pass-through.
• '-' Button: Used to decrease the volume or navigate menu options.
• Gear Button: Used for input selection (short press) or to enter/exit the menu (long press).
• '+' Button: Used to increase the volume or navigate menu options.

Rear Panel

The rear panel includes the following connections:

• Clock input (10MHz IN)
• Coaxial input
• AES input
• USB input
• LAN input
• 220V/110V Voltage switching
• Fuse
• Line out XLR Right
• Line out RCA Right
• IIS input (IIS-G)
• IIS input (IIS-M*)
• Trigger in
• Optical input
• TF card reader
• Update Firmware port
• Line out XLR Left
• Line out RCA Left

Note: Ensure both voltage switches are set to the same voltage when operating the 220V/110V voltage switch to avoid damaging the internal transformer.

Display and Panel Operations

1. Display: The X30 uses a large OLED display for real-time status and function operations. The display shows input channel, external clock status, sampling rate, encoding format, and volume.
2. Input Channel Selection: The X30 has 7 input channels (COAX, AES, OPT, USB, STREAMER, IIS(G), IIS(M*)). Press the small gear key to cycle through them. IIS(G) is GUSTARD format, while IIS(M*) is adjustable and auto-detects PCM/DSD.
3. Volume Adjustment: Use the '+' and '-' buttons to adjust the analog volume from 0dB to -90dB. Pressing '-' at 0dB enters FIXED output mode (pass-through). Pressing '-' when in FIXED mode exits it and allows volume adjustment.

Settings Menu

Long press the small gear button to enter the settings menu. Use the menu button to cycle through options and '+' / '-' buttons to adjust values. Long press the menu button again to return to the main screen.

Menu Directory Tree:

• 1. PCM FILTER (PCM Digital Filter Adjustment)
• 2. DSD FILTER (DSD Digital Filter Adjustment)
• 3. NOS MODE (No Oversampling Filter Mode)
• 4. REF CLOCK (Reference Clock Selection)
• 5. IIS MODE (IIS Pinout Mode Selection)
• 6. PHASE (Phase Setting)
• 7. TRIGGER CH. (Linkage trigger start channel selection)
• 8. TRIGGER VOL. (Link Trigger Boot Volume Selection)
• 9. DISPLAY (Screen Brightness Settings)

Filter Options:

• PCM FILTER: VIVID (fast roll-off, detailed), GENTLE (slow roll-off, soft), COMPOSITE (hybrid).
• DSD FILTER: 47K, 50K, 60K, 70K bandwidth options.
• NOS MODE: Bypasses oversampling filter for direct DSD to ES9039SPRO. May cause slight clicking during format switching.

Reference Clock:

• INTERNAL: Uses the built-in OCXO.
• EXT. 10Mhz: Connects to an external 10MHz reference source (e.g., GUSTARD C16 or C18).

The display shows 'EXT' when the external clock is locked and 'EXT ERR' if the clock is lost or deviates significantly.

IIS MODE:

• IIS(G): GUSTARD pinout, requires DSD FLAG from the front end for DSD playback.
• IIS(M*): Adjustable pinout, auto-detects PCM/DSD.

Diagrams show pinouts for MODE1 (GUSTARD), MODE2, MODE3, and MODE4, all using the IIS OVER HDMI connector. Users are cautioned not to connect to a standard HDMI port.

Phase Setting:

• NON-inverted: RCA is normal phase, XLR is US standard (1 ground, 2 hot, 3 cold).
• Inverted: RCA is reverse phase, XLR is Japanese/European standard (1 ground, 2 cold, 3 hot).

Trigger CH:

• The X30 can be triggered by a 12V linkage signal to turn on from standby. The input channel can be set to automatically switch upon trigger.
• Options include LAST (previous input), COAX, AES, OPT, USB, STREAMER, IIS(G), IIS.
• If the 12V trigger signal drops to 0V, the X30 enters standby.

Trigger VOL:

• Sets the output volume after a 12V trigger.
• Options: LAST (previous volume), FIXED (full volume), -20dB, -30dB, -40dB.

DISPLAY:

• AUTO: Automatically reduces screen brightness.
• AUTO OFF ALL: Automatically turns off the screen.
• AUTO OFF DISPLAY: Automatically turns off the screen display.

Reducing brightness or turning off the screen is recommended to prevent OLED burn-in and ghosting.

Infrared Remote Control

Enter DAC mode by long pressing the DAC key for 3-5 seconds.

• ① Standby: Switches between standby and working.
• ② Menu: Enters the settings menu.
• ③ Pad with 4 direction keys: Navigate menus and adjust values. Up/down keys switch input channels on the main screen.
• ④ Back: Returns to the main screen.
• ⑤ Vol-: Decreases volume.
• ⑥ Vol+: Increases volume.

Note:

• Ensure proper distance and angle for remote operation.
• Obstacles may interfere with the signal.
• Remove the battery if the remote is unused for over a month.
• Clean battery leaks thoroughly and replace the battery if necessary.
• The remote may not work correctly with other devices.

The remote has mode buttons for DAC, AMP, and STREAM, used to control different types of Gustard products.

Operation Introduction of Streamer

After connecting the X30's RJ45 to your LAN:

1. Select the X30 to Streamer channel and wait for the system to boot up (approx. one minute, until DSD 24.5MHz is displayed).
2. In a web browser on a PC, MAC, tablet, or iPhone on the local network, enter: http://X30.local

The settings page allows you to:

• Turn off unused streaming protocols to optimize performance.
• Perform online upgrades for the Streamer.

These operations can also be performed via the dedicated Streamer APP.
