Ulanzi AM18 U-Mic 2-Person Wireless Microphone System

The Ulanzi AM18 U‑Mic 2‑Person Wireless Microphone System is a dual‑channel wireless audio solution designed for content creators, vloggers, interviewers, and mobile journalists who need reliable stereo capture for a two‑person setup. It includes two clip‑on transmitters with built‑in omnidirectional microphones and a dual‑channel receiver, enabling simultaneous recording of two independent audio sources. The system uses a 2.4 GHz digital transmission for stable signal up to approximately 328 ft (100 m), offering freedom of movement without the constraints of cables.

Designed to work with DSLR/mirrorless cameras, smartphones, and USB‑C equipped devices, the receiver provides both 3.5 mm TRS output and USB‑C connectivity. It features onboard controls and a TFT touchscreen display for intuitive tweaking of gain, modes (stereo/mono/safety track), and monitoring. With backup onboard recording on each transmitter and a portable charging case, this system covers both primary and safety audio capture for field use.
