The Shure UR1-J5 Bodypack Transmitter is designed for use with the UR4S or UR4D receivers. The transmitter features cast magnesium housing, protecting the transmitter from rigorous use while remaining lightweight. The UR1-J5 bodypack does not include a microphone; however the TA4-male connection is compatible with Shure lavaliers, head-worn microphones and instrument cables featuring a TA4-female connection. The transmitter is capable of 10 or 50 mA output power, enabling extended range whenever necessary. The UR1-J5 features a backlit LCD display and is powered up to 9 hours on 2 AA alkaline batteries (low RF power).
