The Saramonic TX-XLR9 is a wireless plug-on transmitter compatible with the UwMic9-RX9 dual-channel camera-mount receiver.
Built with a sturdy metal construction, the TX-XLR9 can be attached to any wired XLR microphone to convert it into a wireless mic.
You can plug a handheld mic for man-on-the-street interviews or a shotgun mic for wireless booming (both types of mics are available separately).
The plug-on provides 48V phantom power, giving you the option to use either a dynamic or a condenser microphone. A locking XLR connector holds the attached microphone firmly in place.
The TX-XLR9 is easy to use, offering fast IR sync with the receiver. It can be muted with the press of a button, and a flashing red LED reminds you that it's muted.
A backlit LCD display lets you clearly see the operating conditions, allowing you to make quick adjustments to the intuitive menus in the brightest or darkest environments. The buttons can be locked when in use to prevent accidental muting or powering off.
The transmitter also features a selectable RF power output. The Low setting lets you extend battery life in situations where the subject is close to the receiver. Medium and High settings are useful when the subject is positioned further away, or when you're using the TX-XLR9 in an environment with more potential interference.
Two AA batteries (available separately) are required for operation.
