6. Operation
6.1 Connecting Microphones and Instruments
- Connect your microphone to an XLR input or your instrument (guitar, bass, keyboard) to a TRS input on the front panel.
- If using a condenser microphone, press the corresponding +48V button to supply phantom power. Ensure dynamic microphones do not have phantom power enabled.
- Slowly turn the Gain knob for the connected input clockwise until you achieve a healthy signal level in your recording software, avoiding clipping (distortion).
6.2 Monitoring
Connect headphones to the 1/4" TRS headphone output on the front panel. Use the Monitor knob to blend between the direct input signal (for zero-latency monitoring of your performance) and the playback from your computer/mobile device. The Master Volume knob controls the overall output level to your studio monitors connected to the rear Line Out ports.
6.3 Live Streaming with Mobile Devices

The Duo 44 Live allows you to send audio from your computer directly to your connected mobile device for live streaming applications. This enables you to mix your computer's audio (e.g., backing tracks, virtual instruments) with your live microphone/instrument inputs and send the combined signal to your streaming app.
- Connect your mobile device using either the Analog (TRRS) or Digital (USB-C) connection.
- In the ProDriver4 software (Windows) or your macOS audio settings, configure the routing to send your desired computer audio outputs to the mobile device output channels of the Duo 44 Live.
- Open your streaming application on your mobile device. It should detect the Duo 44 Live as an external microphone/audio input.
- Adjust the input levels on the Duo 44 Live and within your streaming app to achieve a balanced mix.
6.4 MIDI Connectivity
Connect your MIDI keyboard, controller, or other MIDI devices to the MIDI IN and MIDI OUT ports on the rear panel. The Duo 44 Live will act as a MIDI interface, allowing your computer to send and receive MIDI data from your external hardware. Ensure your DAW is configured to recognize the Duo 44 Live's MIDI ports.

8. Troubleshooting
| Problem | Possible Solution |
|---|---|
| No power/device not recognized by computer | Ensure the USB cable is securely connected to both the interface and the computer. Try a different USB port or cable. If using an external power supply, ensure it is connected and functional. Reinstall drivers if on Windows. |
| No sound from inputs | Check input gain knobs are turned up. Ensure +48V phantom power is enabled for condenser microphones. Verify the correct input is selected in your DAW/software. Check cable connections. |
| No sound from outputs/headphones | Check Master Volume and Headphone Volume knobs. Ensure speakers/headphones are connected and powered. Verify the Duo 44 Live is selected as the output device in your operating system and DAW. |
| Low overall volume | Adjust input gain, master volume, and headphone volume. Check levels within your DAW/software. Ensure no software attenuators are active. |
| TRRS output not working for mobile device | Ensure the TRRS cable is fully inserted and compatible with your mobile device. Some phone cases may prevent full insertion. Test with another TRRS cable if possible. Verify mobile device settings recognize external audio. |
