4. Einrichtung
4.1 Erstverbindung
- Stromanschluss: Connect the provided power cable to the DX5 II's power input and then to a suitable AC power outlet.
- Digital Source Connection: Choose your preferred digital input (USB, Coaxial, Optical, or Bluetooth).
- USB: Connect the DX5 II to your computer using the supplied USB cable. For Windows ASIO applications, you may need to install Thesycon drivers (drivers are not required for other operating systems like macOS, Linux, iOS, Android).
- Koaxial/Optisch: Connect your digital audio source using appropriate cables.
- Bluetooth: Attach the Bluetooth antenna to the designated port on the rear panel.
- Ausgangsanschluss: Connect your headphones or active speakers to the appropriate output jacks on the front or rear panel.
4.2 Treiberinstallation (nur Windows)
For optimal performance and ASIO support on Windows 10/11, download and install the latest Thesycon USB driver from the official TOPPING website. Follow the on-screen instructions for installation. No drivers are needed for macOS, Linux, iOS, or Android devices.
5. Bedienungsanleitung
5.1 Ein-/Ausschalten
Flip the power switch on the rear panel to turn the DX5 II on or off.
5.2 Eingangsauswahl
Press the 'INPUT' button on the front panel or use the remote control to cycle through available digital inputs (USB, Coaxial, Optical, Bluetooth).
5.3 Lautstärkeregelung
Rotate the large knob on the front panel to adjust the volume. The volume level will be displayed on the screen. You can also use the volume buttons on the remote control.
5.4 Bluetooth-Kopplung

- Once paired, audio will stream wirelessly to the DX5 II.
5.5 Aurora UI Navigation
The 2.0-inch full-color screen features the Aurora UI. Use the 'MENU' and 'HOME' buttons, along with the pressable knob, to navigate through settings. You can customize background colors, display modes (FFT, VU meter, playback info), and assign functions to the knob.
5.6 Precision PEQ Adjustment
The DX5 II offers a 10-band high-precision PEQ system. This can be adjusted via PC software to fine-tune frequency, gain, and bandwidth. You can import target curves, apply curve compensation, and save multiple profiles. Independent PEQ profiles can be set for headphone and line-out outputs.
5.7 Voramp Modus
The DX5 II can operate in a "preamp" mode, allowing direct volume adjustment when connected to a pure amplifier or active speakers. This eliminates the need for a separate preamplifier. The device automatically restores the last set volume when switching outputs.
5.8 12V-Trigger
The DX5 II is equipped with 12V Trigger input and output ports. This feature allows it to be triggered by other devices, or to actively trigger other devices, to switch on and off synchronously, enabling seamless system integration.
