• +48V Phantom Power: Press the +48V button to supply phantom power to condenser microphones. Ensure dynamic microphones do not have phantom power applied.
• PAD Button: Use the PAD button to attenuate input signals by a fixed amount (e.g., -20dB) if the input source is too strong, preventing distortion.
• GAIN Control: Adjust the GAIN knob to set the input sensitivity for each channel. Aim for a strong signal without clipping (distortion).
• 2-Band EQ (LOW/HIGH): Use the LOW and HIGH knobs to adjust the bass and treble frequencies of the input signal.
• LEVEL Control: Adjust the LEVEL fader or knob to control the overall volume of the channel in the mix.

2. USB Audio Interface

• PHONE Output: Connect headphones to the PHONE jack to monitor the main mix. Adjust the dedicated PHONE level knob for comfortable listening.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the mixer's surface. Avoid using liquid cleaners or solvents, as they may damage the finish or internal components.
• Storage: When not in use, store the mixer in a cool, dry place away from direct sunlight and extreme temperatures.
• Cable Management: Ensure all cables are neatly organized and not under strain to prevent damage to connectors and ports.

Troubleshooting

• No Power: Check the power adapter connection and ensure the power outlet is functional.
• No Sound Output: Verify all input and output cables are correctly connected. Check the GAIN and LEVEL controls for each channel and the MAIN output fader. Ensure connected speakers or headphones are powered on and functioning.
• Distorted Sound: Reduce the GAIN for input channels that are clipping. Check the PAD button if the input signal is too strong. Ensure output levels are not overdriving connected amplifiers or speakers.
• Bluetooth Connection Issues: Ensure the mixer's Bluetooth is active and your device is in pairing mode. Try restarting both the mixer and your Bluetooth device.
• Humming Noise: Ensure all audio cables are properly shielded. If connecting to a PC for recording, a noise filter cable may help reduce ground loop hum.
