Front Panel Introduction

The front panel of the Gustard X30 features a display and control buttons:

• Display: Shows input channel, encoding format, sample rate, and volume level. It also displays menu items.
• Power Button: Switches between standby and working states. The rear power switch keeps the unit in standby when turned on.
• Volume Display: Shows volume from -90dB to 00dB. "FIXED" indicates fixed volume output (bypass).
• "-" Button: Typically used to decrease volume. In menu mode, it navigates options.
• Gear Button (⚙️): Short press for input selection. Long press to enter/exit the settings menu. In the menu, short press navigates menu items.
• "+" Button: Typically used to increase volume. In menu mode, it navigates options.

Rear Panel Interface

The rear panel provides various input and output connections:

• Outputs: Balanced XLR (Left/Right), Single-ended RCA (Left/Right).
• Digital Inputs: USB (Type B), Coaxial, AES, Optical, LAN, IIS (G/M*), 10MHz IN (Clock Input).
• Other: Trigger Input/Output (12V), TF Card Slot, Firmware Update Port, Power Input, Fuse, Voltage Selector (115V/230V).

Important Note: When switching the 220V/110V voltage selector, ensure both switches are set to the same voltage to prevent damage to the internal transformer.

Display Introduction

The X30 uses a large OLED display for real-time status and operation.

• Input Channel: Displays the currently selected input source.
• External Clock Display: Indicates if an external clock source is used.
• Encoding Format: Shows the audio codec (e.g., DSD).
• Sample Rate: Displays the audio sample rate (e.g., 22.4M).
• Volume: Shows the current volume level.

Input Channel Selection: The X30 has 7 input channels. Press the gear button (⚙️) to cycle through COAX, AES, OPT, USB, STREAMER, IIS(G), and IIS(M*).

Volume Adjustment (VOLUME): Use the "+" and "-" buttons to adjust the analog volume. Volume can be attenuated from 00dB down to -90dB. Pressing "+" at 00dB engages the fixed output mode (FIXED), bypassing volume control.

Settings Menu

Access the settings menu by long-pressing the gear button (⚙️) on the front panel. Use the "+" and "-" buttons to navigate and adjust settings.

Menu Structure:

• 1. PCM FILTER: Adjusts the PCM digital filter. Options include VIVID, GENTLE, COMPOSITE.
• 2. DSD FILTER: Selects DSD filter bandwidth. Options: 47K, 50K, 60K, 70K.
• 3. NOS MODE: Enables or disables the No Oversampling mode. Options: DISABLE, ENABLE. (Note: Enabling NOS may cause a slight click when switching between PCM and DSD.)
• 4. REF CLOCK: Selects the reference clock source. Options: INTERNAL (internal OCXO clock), EXT. 10Mhz (external 10MHz clock).
• 5. IIS MODE: Configures the IIS input pinout. Supports IIS(G) (fixed Gustard pinout) and IIS(M*) (adjustable pinout).
• 6. PHASE: Sets the output phase. Options: NON-inverted (RCA normal, XLR US standard), Inverted (RCA inverted, XLR Japan/Europe standard).
• 7. TRIGGER CH.: Selects the input channel for 12V trigger activation. Options include LAST (previous input), COAX, AES, OPT, USB, STREAMER, IIS(G), IIS.
• 8. TRIGGER VOL.: Sets the output volume level for 12V trigger activation. Options: LAST (previous volume), FIXED, -20dB, -30dB, -40dB.
• 9. DISPLAY: Adjusts screen brightness and behavior. Options: AUTO, AUTO OFF ALL, AUTO OFF DISPLAY.

Infrared Remote Control Operation

The remote control allows for convenient operation of the X30.

• [Power Button]: Toggles standby/working mode.
• [MENU Button]: Enters the settings menu.
• [Navigation Buttons (Up/Down/Left/Right)]: Navigate menus and select options. Press the center button to mute/unmute.
• [Return Button]: Returns to the main screen.
• [VOL- Button]: Decreases volume.
• [VOL+ Button]: Increases volume.

Note: For DAC products, press and hold the DAC button for 3 seconds to enter DAC mode. AMP and STREAM modes are for other Gustard products.

Important: Ensure clear line-of-sight for the remote. Remove batteries if not in use for extended periods.

USB Driver Installation on Windows

This section guides you through installing the necessary USB drivers for Windows systems.

• The driver is compatible with various Windows versions (7 SP1+, 8, 10, 11).
• MAC OS systems have built-in drivers.
• Drivers can be found on the included CD or downloaded from www.gustard.cn.
• For desktop users, it is recommended to use native USB 2.0 ports, preferably on the rear of the computer.
• Connect the X30 via USB, power it on, and Windows should detect the new hardware. Follow the on-screen prompts.
• Run the installer executable (e.g., Gustard_UsbAudio_v4.82.0_setup.exe) and follow the installation wizard steps (Next, Install, Finish).
• If prompted by User Account Control, click "Yes".
• If a "Setup requires that the device is..." error appears, try reconnecting the USB cable or restarting the device.

Foobar2000 Setup for DSD Hardware Decoding

This guide explains how to configure Foobar2000 for DSD hardware decoding using the Gustard X30.

1. Install ASIO Proxy: Run the ASIOProxyInstall-0.7.2.exe installer from the provided folder.
2. Open Foobar2000 Preferences: Launch Foobar2000 and go to File > Preferences.
3. Install Components: In the Preferences window, navigate to Components. Click Install... and select the ASIO and SACD components (e.g., foo_out_asio.fb2k-component and foo_input_sacd.fb2k-component) from the foobar2000_DSD_0.7.X folder. Click Apply. Foobar2000 may prompt for a restart.
4. Configure ASIO Output: Go to Playback > Output > ASIO. Select ASIO: foo_dsd_asio as the device. Adjust buffer length if necessary.
5. Configure SACD Output: Go to Tools > SACD. Set Output Mode to DSD.

Troubleshooting:

• ASIO option missing: Ensure the ASIO component is installed correctly. Drag and drop foo_out_asio.fb2k-component into the Components list if it's not detected.
• SACD option missing: Ensure the SACD component (e.g., foo_input_sacd.fb2k-component) is installed.
• Playback errors: This can occur due to version conflicts between ASIOProxy and SACD components. Ensure you are using compatible versions (e.g., ASIOProxy v0.7.2 with SACD component v0.7.8). If issues persist, consider reinstalling Foobar2000 or using older/newer versions of components as suggested in the manual.
