Audio Technica ATW 252H Wireless Microphone System

ATW 252H Wireless Microphone System description:

The Audio-Technica ATW 252H Wireless System provides reliable performance, easy setup and clear, natural sound quality.

The Audio-Technica ATW 252H VHF wireless system includes a receiver and a handheld microphone/transmitter on a specific crystal-controlled frequency (173.800MHZ). A novel dipole antenna system on the receiver improves operation by providing a ground element in addition to the usual signal element.
