Setup Instructions
The Ulanzi J12 system is designed for plug-and-play convenience. Follow these steps to get started:
-
For Android Phones (Important):
- Download a third-party camera or recording application (e.g., OpenCamera, Cinema-FV) as some Android phones may not support external microphones with their native camera app.
- For certain brands like OPPO, VIVO, IQOO, and Realme, you may need to go to your phone's settings, search for "OTG", and enable it for the microphone to function correctly.
- Ensure the third-party app has microphone permissions enabled in your phone's settings.
- Plug in the Receiver: Insert the receiver (Lightning or Type-C, depending on your phone model) directly into your smartphone's charging port.
- Turn on the Mic Transmitter(s): Press the power button on the mic transmitter(s). The indicator light will show its status.
- Automatic Connection: The system will automatically connect. Once connected, you can begin recording.
Note: If using with a PC or laptop, a USB-A to USB-C adapter (not included) is required.
Operating Instructions
The Ulanzi J12 offers several features to enhance your audio recording:
- Noise Reduction: The built-in intelligent denoise module helps filter out ambient noise. To activate/adjust noise reduction, single-click the designated button on the transmitter. Each click cycles through different levels of noise reduction (first-level, second-level, third-level). A fourth click will turn off noise reduction.
- Mute Function: Double-click the button on the transmitter to mute the microphone. Double-click again to unmute.
- Reverberate Mode: Triple-click the button on the transmitter to activate reverberate mode.
- Dual Microphone Recording: The system supports simultaneous recording with two microphones, perfect for interviews or two-person content creation.
Maintenance
- Keep the device dry. Avoid exposure to moisture or liquids.
- Clean the microphone and receiver gently with a soft, dry cloth. Do not use harsh chemicals or abrasive materials.
- Store the system in its charging case when not in use to protect it from dust and physical damage.
- Charge the device regularly to maintain battery health, even if not used frequently.
Troubleshooting
- Q: The microphone is not working with my Android phone.
- A: Ensure you have downloaded a third-party recording app. For OPPO, VIVO, IQOO, and Realme phones, check if "OTG" is enabled in your phone's settings. Also, verify that the app has microphone permissions.
- Q: There is noise when I turn on the microphone.
- A: First, confirm that both transmitters are automatically connected to the receiver. Utilize the noise reduction feature by single-clicking the button on the transmitter to cycle through levels. Note that if ambient noise exceeds 60 decibels, it may be recognized as a main sound and not fully reduced.
- Q: Can I use this with my GoPro, DJI, Insta360, or other camera devices?
- A: No, this system is designed for use with phones and laptops only, not dedicated camera devices.
- Q: Can I use this with my PC or laptop?
- A: Yes, but you will need a USB-A to USB-C adapter (not included in the package) to connect the receiver to your computer.
- Q: My product is not working at all.
- A: Please re-check the setup and operating steps in this manual. If the issue persists, contact customer support with your phone model and a video demonstrating the problem for further assistance.
