The HT420 Professional Wireless Handheld Transmitter from AKG features a dynamic microphone capsule that is designed to reject audio feedback, a noiseless on/off/mute switch, a gain control knob, and an LED indicator light. It can be used when paired with a SR420 receiver (sold separately) in applications for live stage, theater, conferences, rehearsals, lectures, and more.
The microphone is powered by a single AA battery which provides between six and eight hours of operating time with a range of approximately 98'. The transmitter also includes charging contacts for use with rechargeable batteries and the optional AKG CU400 rechargeable base station (sold separately).
