Audio-Technica's ATW-201 professional VHF wireless system includes an ATW-R200 receiver, ATW-T201 transmitter, and Hi-Z instrument cable. The ATW-R200 receiver design features an innovative docking power supply configuration. An AC power adapter housed in a compartment in the receiver uses an IEC-standard detachable power cordset. Furthering its flexibility, the power adapter may be easily removed from the receiver case, permitting its use as a conventional in-line AC adapter. A novel dipole antenna system on the receiver improves operation by providing a ground element in addition to the usual signal element.
