This is a slightly used 2 ATW Wireless Microphone system. I bought it as a back up but have never needed it so it's time to go.

Works perfect. System comes with the small bag and everything else seen in the pictures. 

First one  - FREQ. 169.505               Second one - FREQ. 171.905
       ATW-T201 Transmitter                                        ATW-T201 Transmitter

The following is the manufacture information:

Audio-Technica’s Freeway 200 Series Wireless System provides proven performance in a variety of settings. 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. 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.

Good luck bidding, if you have any question or want to see more pictures please let me know.
