Operating Instructions

Understanding the controls on your AudioBox USB 96 is crucial for optimal performance.

• Mic/Inst Inputs (1 & 2): These combo jacks accept both XLR (for microphones) and 1/4-inch TS (for instruments) connectors.
• 48V Phantom Power: Press this button to supply 48V phantom power to the XLR inputs for condenser microphones. Ensure it is off when not needed or when using dynamic microphones.
• Gain Knobs (Mic/Inst 1 & 2): Adjust these knobs to set the input level for your microphones or instruments. Aim for a strong signal without clipping (indicated by the Clip LED).
• Mixer Knob: This control blends the input signal (direct monitoring) with the playback signal from your computer. Turn it towards "Inputs" to hear more of your live input, and towards "Playback" to hear more of your computer's audio. This provides zero-latency monitoring.
• Playback Knob: Adjusts the overall playback level from your computer.
• Main Knob: Controls the output level to your main studio monitors connected to the rear panel.
• Headphone Knob: Adjusts the volume for the headphone output.

For recording, ensure your DAW software is configured to use the AudioBox USB 96 as its audio input and output device. Adjust input gain levels to prevent clipping, and use the Mixer knob for comfortable monitoring during recording sessions.

Maintenance

To ensure the longevity and optimal performance of your AudioBox USB 96, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Avoid abrasive cleaners, solvents, or waxes.
• Environment: Operate and store the device in a clean, dry environment, away from direct sunlight, excessive heat, and moisture.
• Protection: While the AudioBox USB 96 features a durable steel chassis, avoid dropping or subjecting it to severe impacts. Protect the knobs and connectors from physical damage.
