Godox TX3-XLR Plug-On XLR Transmitter

The TX3-XLR operates on two AA batteries and is equipped with an On/Off switch that doubles as a mute button. An easy-to-read backlit OLED screen with adjustable brightness shows the transmitter's frequency, channel/group, input level, muting, and battery life.
The system offers 96 manually selectable frequencies to choose from in order to create an interference-free transmission channel for wireless transmission to the RX1 receiver (available separately). The transmitter has two levels of RF transmission power: The high 50mW setting improves signal quality when working at greater distances, while the low 20mW setting offers maximum battery life when working at close range.
