The RØDE's TX-M2 is a digital wireless microphone that sends audio to compatible RODE receivers at distances of up to 328 feet. The microphone delivers out-of-the-box capabilities for vocalists, presenters, and DJs, with a 140 dB SPL and a frequency response of 35 Hz to 20 kHz, making it ideal for live shows, conferences, special events, ceremonies, and more. To ensure a secure transmission, the microphone uses 128-bit encryption over its 2.4 GHz fixed frequency agile technology. Its long-distance range is ensured by a diversity antenna positioned on the bottom. The microphone has minimal handling noise, which reduces unpleasant rumbling, as well as simple features including a mute switch and a pair button for one-touch pairing with compatible receivers.Even better, this microphone can be powered by either the supplied LB-1 lithium-ion rechargeable battery or two AA batteries.
