P1 FAQ

Part 1: Basic Connection and Recognition Issues

Q1: the audio interface indicator light does not turn on after connecting to the computer?

Q2: the audio interface indicator light does not turn on after connecting the audio interface's OTG port to a mobile phone, and the phone cannot use the audio interface?

Q3: No sound is recorded on the computer after connecting a condenser microphone to the audio interface?

Q4: The computer fails to recognize the "Maono P1" device after the audio interface is connected?

Part 2: Detailed Explanation of Button and Port Functions

Q5: What is the purpose of the Main out port?

Q6: What is the function of the Camera port?

Q7: How to enable the audio interface's monitoring function?

Part 3: Software Usage

Q8: How to connect and use with OBS?

1.Open OBS and add Audio Input Capture.

2.Select the P1 audio input device.

The basic sound settings on OBS are completed after the above operations.

Q9: How to connect and use with Studio One?

2.Open Studio One and click the audio interface icon under Settings.

3.Select Maono as the audio device and click OK.

4.After the settings are completed, create a new project to start recording.

Part 4: Audio Issues (Abnormal Sound/No Sound/Echo, etc.)

Q10: No sound during recording/live streaming after the audio interface is connected to the computer?

• Check if the gain knob on the audio interface is accidentally muted🔇 (the knob's aperture stays solid red⭕ in this case); short-press the gain knob again to unmute.
• Check if the audio interface's gain knob is set too low, resulting in inaudibly low volume. The gain level can be judged by the proportion of the green light in the knob's aperture—the larger the gain, the higher the proportion of green light.
• Check if the computer's input settings are set to the P1 audio device and verify the volume bar level.

• Check if the audio input volume on third-party recording or live streaming software is set too low or muted.

Q11: Sound is only heard in one ear of the headphones?

Q12: There is a humming/buzzing sound when the audio interface is connected to the computer?

• Do not hold the microphone by hand; use a mic stand to fix it instead.
• Ensure the USB cable and XLR cable are securely connected, especially the microphone port.
• Do not use adapters!! First, replace the USB port the audio interface is connected to. For desktop computers, use the USB ports at the back of the host.
• The inherent background noise of the audio interface or ambient noise in a normal environment: Move to a quieter environment to use the device.
• Excessively high microphone gain or a noisy environment, causing the microphone to pick up ambient sound beyond the audio interface's noise reduction threshold: Lower the microphone gain to resolve the issue.
• Aging computer ports or poor grounding, or aging mains power circuits/power strips leading to electric leakage and persistent humming: Try using a different computer in another environment, or test with a mobile phone instead.
• Strong electromagnetic radiation from electronic devices near the microphone (e.g., WiFi routers, video lights) causing interference: Move to a different environment (e.g., from the living room to the bedroom).
• Noise caused by software incompatibility: Use the computer's built-in voice recorder for recording and close third-party software to avoid software conflicts or noise from audio effects.
• For mobile devices (phones/tablets): Apple devices must use MFI-certified cables; for other brands, use original adapters as much as possible.

Q13: Audio clipping/distortion occurs?

• Check if the gain knob on the audio interface is set too high— the aperture will show red🟥 if the sound is overloaded. Adjust the input gain to an appropriate level by rotating the knob or enabling automatic gain control.
• Check the computer's sound settings and lower the audio input volume if it is set too high.

Part 5: Advanced Q&A

Q14: Will a dynamic microphone be damaged if the 48V phantom power is accidentally turned on?

Q15: Can dynamic microphones and condenser microphones be used together?

• If 48V phantom power is a global switch: ⚠️ Condenser microphones require 48V power on, while dynamic microphones can withstand it but are not recommended for long-term power supply; ⚠️ Ribbon microphones are strictly prohibited from being connected!
• Optimal solution: Ensure 48V phantom power is controlled by separate channels before using the two types of microphones together.

Q16: How to select the sample rate/bit depth?
