Samson UHF Series One AT831 Wireless Lavalier System

Samson designed the UHF Series One to give everyone the highest level of wireless performance at affordable prices. Fully professional, the receiver features a True Diversity design with 2 independent receivers, S.A.W. (Surface Acoustic Wave) technology, and built-in, tuned, and molded antennas for the most stable RF reception possible.The UR1 receiver front panel includes an RF level meter, Squelch control, Peak audio LED, and Power switch. The system also features a super-compact "beeper-size" beltpack and a 3-segment LED "battery-life" meter on all transmitters that indicates when the battery is running low.

Patent-pending direct Phase-Lock Loop transmitter technology "locks" in the signal to ensure stable transmission. UHF Series One is available with the popular Samson Qmic vocal and headset mics and a variety of other mic elements. It also has both a balanced XLR output (mic/line switchable) and unbalanced 1/4 in. output. Series One. UHF wireless for the next millenium — now.

System Includes: UR1 True Diversity Receiver, UT1L Beltpack Transmitter, and Audio Technica AT-831 Lavalier Mic with Detchable P3 Connector.
