The UWMIC9 RX9 + TX9 + TX9, 96-Channel Digital UHF Wireless Dual Lavalier Mic System from Saramonic is a portable, camera-mountable wireless system for capturing audio with dual subjects. It can be used in several environments for video, field recording, interview, broadcast TV, and ENG applications. The system's RX9 camera-mountable receiver features a wide-switching RF bandwidth and an easy-to-read LCD display. It is built with infrared synchronization between transmitter and receiver, an auto-scan function, and can search for an available transmission frequency. The headphone jack provides real-time monitoring with headphones, which is useful for cameras that lack a monitor output.
