4. Setup Guide

4.1 Power Connection

The E30 II DAC requires a 5V DC power supply. You can power it using a USB port from a PC, a standard phone charger, or a power bank. The device features a built-in protection circuit to prevent damage from incorrect power input.

4.2 Audio Connections

Connect your audio sources to the E30 II using the appropriate input ports:

• USB Input: For connecting to a computer (PC, Mac, Linux), smartphone, or tablet.
• Coaxial Input: For connecting to digital audio sources like CD/DVD players, game consoles, or digital turntables with a coaxial output.
• Optical (Toslink) Input: For connecting to digital audio sources like TVs, game consoles, or media players with an optical output.

Connect the E30 II's RCA outputs (Right channel 'R ch' and Left channel 'L ch') to your amplifier, active speakers, or headphone amplifier using RCA cables.

4.3 Driver Installation (for USB Input)

For Windows operating systems (Windows 10, Windows 11), an ASIO driver is required for optimal performance. This driver is based on XMOS XU208 and Thesycon custom driver. For other operating systems like Mac, Linux, iOS, and Android, the E30 II is typically plug-and-play and does not require specific driver installation.

5. Operating Instructions

5.1 Power On/Off and Auto On/Off

The E30 II can be powered on or off by pressing and holding the multifunction touch button (3) on the front panel. It also features an auto power-on function: when a signal is detected on the active input, the device will automatically turn on.

5.2 Input Selection

To switch between USB, Coaxial, and Optical inputs, short press the multifunction touch button (3) on the front panel or use the 'SEL' button on the remote control.

5.3 Volume Control and Preamp Mode

The E30 II includes a built-in preamp mode, allowing you to control the output volume directly. Use the volume up/down buttons on the remote control to adjust the volume. This feature is particularly useful when connecting directly to active speakers or a power amplifier without a separate preamplifier.

5.4 Filter Modes and Pure DAC Mode

The E30 II offers various digital filter modes to customize the sound to your preference:

• PCM Filters: Six different filter modes are available for PCM audio playback. These can be cycled through using the remote control.
• DSD Modes: Two DSD modes are available.
• Pure DAC Mode: This mode allows for direct DSD playback, bypassing certain internal processing to deliver an unaltered, high-resolution audio experience.

6. Maintenance

To ensure the longevity and optimal performance of your TOPPING E30 II DAC, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe the exterior of the device. Avoid using liquid cleaners, aerosols, or abrasive materials, as they may damage the finish or internal components.
• Placement: Place the DAC on a stable, flat surface away from direct sunlight, heat sources, and excessive moisture. Ensure adequate ventilation around the unit.
• Handling: Handle the device with care. Avoid dropping it or subjecting it to strong impacts.
• Power Off: If the device will not be used for an extended period, it is recommended to disconnect it from the power supply.

7. Troubleshooting

If you encounter issues with your E30 II DAC, please refer to the following common problems and solutions:

• No Power:
  • Ensure the 5V DC power cable is securely connected to both the DAC and a working power source (e.g., USB port, phone charger).
  • Verify the power source is active and providing 5V.
• No Sound Output:
  • Check if the correct input source (USB, Coaxial, Optical) is selected on the E30 II. The LED screen should display the active input.
  • Ensure the RCA output cables are securely connected to your amplifier/active speakers and the E30 II.
  • Verify that your amplifier/active speakers are powered on and set to the correct input.
  • If using USB input, ensure the correct audio output device (TOPPING E30 II) is selected in your computer's sound settings and that the necessary drivers are installed (for Windows).
  • Check the volume level on the E30 II and your connected audio equipment.
• Distorted Sound / Poor Audio Quality:
  • Ensure all cables are securely connected and not damaged.
  • Try a different audio source or cable to rule out external issues.
  • Verify the sample rate displayed on the E30 II matches the source audio.
  • If using USB, ensure the computer's audio settings are configured correctly (e.g., bit depth and sample rate).
• Remote Control Not Responding:
  • Check if the remote control's battery needs replacement.
  • Ensure there are no obstructions between the remote and the DAC's remote control receiver (2).
