I purchased these about ten years ago from a retiring sound man in Hollywood to use on a local TV show and some documentaries. They are in very good condition. Lectrosonics are the most durable and reliable wireless systems in the business. In fact, they are the industry standard. They are built to military specs. The signal fidelity is the equivalent of having a piece of wire connecting the transmitter to the receiver. They will provide a lifetime of service. These kits will enable you to do Electronic News Gathering, Pro Video work, sound/dialogue acquisition for the Motion Picture Industry, Surveillance and a variety of other applications. Included in the sale are: - 2 Lectrosonics UCR 195 Compact UHF Receivers - 2 Lectrosonics UM 195b UHF Belt-Pack Transmitters - 2 Lectrosonics M150 Lavalier Microphones w/ TA5F connectors - 2 Antennas (Rx and Tx) for each system - 2 AC power supplies/cords for the receivers - 1 Vinyl case to hold both sets The Receiver will run on two 9 volt batteries OR the provided AC power supply and the Transmitter will run on a single 9 volt battery. The battery life is about 7 to 8 hours continuous. (Alkaline or Lithium) The asking price of $800 for both sets is firm. No trades. Cash only. I prefer to sell these as two sets but I will consider $450 for each set sold separately. Thanks for looking!
