AUDIO-TECHNICA ATW251L VHF Freeway Lavalier Wireless System Includes: Advanced dipole antenna system. Available in three traveling frequencies. Removable docking power supply inserts into back of receiver. Adjustable squelch control.
NOTE: Select FREQUENCY Audio-Technicas Freeway 200 Series Wireless Systems are designed to provide reliable performance, easy setup and clear, natural sound quality. Each 200 Series professional VHF wireless system includes a receiver and either a body-pack transmitter or a handheld microphone/transmitter on a specific crystal-controlled frequency. A novel dipole antenna system on the receiver improves operation by providing a ground element in addition to the usual signal element.
