Ulanzi J12 Overview
For use in two-person mobile journalism or content creation applications, this black J12 2-Person Wireless Microphone System turns your USB-C mobile device into an audio recording machine. The system includes two transmitters with built-in, omnidirectional microphones and one dual-channel receiver—all with a compact form factor. Clips on the back of each transmitter can attach them to the lapel of a shirt, while the plug-in receiver inserts directly into the USB-C port of your compatible smartphone or tablet, which also supplies it with power.
The J12 system boasts a 20m transmission distance. LED indicators on both transmitters display their connectivity and power status. The receiver also features a USB-C port for charging your phone simultaneously. Integrated batteries in the transmitters power the system for a total of 6 hours. When the power runs out, the included charging case recharges them. A built-in intelligent de-noise module ensures your audio remains clean and undistorted. Intuitive plug and play pairing allows you to use the system right out of the box.
