5.2 Driver Installation (Plug and Play)
The NUOSIYA USB Audio Interface is designed for plug-and-play operation. No additional drivers are required for Mac/Win 7 or above operating systems. Your computer should automatically recognize the device upon connection.
5.3 Connecting Instruments and Microphones
- Microphones: Connect your microphone to INPUT1 or INPUT2 using an XLR cable. If using a condenser microphone, activate 48V phantom power.
- Guitars/Instruments: Connect your instrument to INPUT1 or INPUT2 using a 6.35mm TRS cable. For high-impedance instruments like electric guitars, ensure the HI-Z switch for INPUT1 is engaged.
5.4 Connecting Output Devices
- Headphones: Plug your headphones into the PHONE jack on the front panel. Adjust volume using the PHONE knob.
- Studio Monitors/Speakers: Connect your studio monitors or speakers to the OUTPUT L/R jacks on the rear panel using 6.35mm TRS cables.
6. Operating Instructions
6.1 Adjusting Input Gain
Use the GAIN knobs for INPUT1 and INPUT2 to set appropriate input levels. The PK (Peak) indicators will light up if the input signal is too high, indicating potential clipping. Adjust the gain to ensure the PK light only flashes occasionally on the loudest parts of your performance.
6.2 Real-time Monitoring
The device offers zero-latency, real-time monitoring. Use the MIX/MON knob to blend between your direct input signal and the playback from your computer (DAW). This allows you to hear your performance without delay while recording.

6.3 Loopback Function for Streaming/Podcasting
The LoopBack function allows you to record or stream your computer's audio output along with your live inputs (microphone, instrument). This is ideal for live streaming, podcasting, or creating content where you need to capture both your voice/instrument and background music/audio from your computer.
6.4 Software Compatibility
The audio interface is compatible with most major Digital Audio Workstations (DAWs) and recording software, including but not limited to Avid Pro Tools, Ableton Live, and Steinberg Cubase. It also works seamlessly with various podcasting and streaming applications.
