3.3 Software and Driver Installation

For optimal performance, it is recommended to install the dedicated drivers and software for the Sonic Cube II. While the device may function as a generic USB audio device, proprietary drivers often provide lower latency and access to advanced features.

• Windows Users: Search online for "Sonic Cube II Software & Firmware Download". Download and install both the "Sonic Mix Setup" and the "Sonicake USB ASIO Driver". This is crucial for proper device recognition and low-latency performance with DAWs.
• macOS Users: The device is generally plug-and-play with macOS. If specific drivers or software are available, they can be found on the official SONICAKE support website.

After installation, restart your computer and ensure the Sonic Cube II is selected as your audio input and output device in your operating system's sound settings and your preferred Digital Audio Workstation (DAW).

4. Operating Instructions

4.1 Powering On/Off

The Sonic Cube II is USB bus-powered. It powers on automatically when connected to a powered USB port on your computer or mobile device. To power off, simply disconnect the USB cable.

4.2 Input Level Adjustment

• Use the GAIN 1 knob to adjust the input level for the microphone connected to MIC 1.
• Use the GAIN 2 knob to adjust the input level for the instrument or line-level device connected to LINE/INST 2.
• Monitor the input levels in your DAW to avoid clipping (distortion). Aim for levels that peak around -6dB to -3dB.

4.3 Phantom Power (+48V)

If you are using a condenser microphone with the MIC 1 input, you will need to activate +48V phantom power. Press the EFX / +48V switch to engage phantom power. Ensure your microphone requires phantom power before activating it. Dynamic microphones typically do not require phantom power.

4.4 Direct Monitoring and "ON AIR" Function

The ON AIR / MONITOR button allows for direct monitoring, enabling you to hear your input signal in real-time through your headphones or studio monitors without latency. This is essential for recording and live performance.

• Press the ON AIR / MONITOR button to activate direct monitoring.
• When engaged, the button's indicator light will illuminate.
• This function also serves as an "ON AIR" mode for streamlined live streaming, routing your audio directly.

4.5 Output Level Adjustment

Use the large OUTPUT knob to control the overall volume of the balanced outputs (L/R) and the headphone output. Adjust this to a comfortable listening level. The headphone output volume is linked to the main output knob.

5. Software and DSP Effects

The Sonic Cube II includes powerful computer software that expands its capabilities with digital modeling and DSP effects. This software allows you to access a variety of guitar amplifier models, cabinet simulations, and other digital signal processing effects directly on your computer.

• Install the "Sonic Mix Setup" software as described in Section 3.3.
• Launch the software to access the digital modeling and DSP effects interface.
• Experiment with different amp models and effects to shape your sound for recording or live streaming.
• Ensure the software is correctly configured to use the Sonic Cube II as its audio input and output device.
