4. Istruzzjonijiet Operattivi

4.1 Power On/Off

Press the power button on the front panel or use the remote control to turn the unit on or off. The display will illuminate upon power-on.

4.2 Navigazzjoni tal-Interfaċċja tal-Utent

The Centaurus features a 2.0-inch full-color screen and three touch buttons for navigation. Use the buttons to browse menus and adjust settings. The intuitive Aurora UI allows for easy personalization of your listening experience.

4.4 SampLing Modi

Navigate to the 'Advanced' settings in the UI to select your preferred oversampling mode: NOS (Non-Oversampling), OS (Oversampling), or Best. Each mode offers a distinct sonic characteristic.

4.5 PEQ Adjustment

The 10-band high-precision PEQ (Parametric Equalizer) allows for detailed sound customization. Access PEQ settings through the UI to adjust frequency, gain, and bandwidth for each band. You can also import curves and save multiple profiles.

4.6 Operazzjoni Bluetooth

The Centaurus supports Bluetooth 5.1 with LDAC. To enable or disable Bluetooth, navigate to the 'Advanced' settings in the UI. Once enabled, pair your Bluetooth device with the Centaurus.

4.7 USB Mode Selection

The unit supports both USB Audio Class (UAC) 1.0 and UAC 2.0. UAC 1.0 allows for driverless operation with devices like gaming consoles. UAC 2.0 typically offers higher resolution audio. You can switch between these modes in the 'Advanced' settings.
