The Shure ULX Professional Series wireless microphone systems provide professional wireless microphone solutions for broadcast, performances, conferences, houses of worship, schools, and businesses. This combo-system includes a ULXP4 diversity receiver, a ULX1 body-pack transmitter, WL185 lavalier and ULX2 handheld transmitter with a Shure SM58 cardioid head.

The ULXP4 receiver operates on UHF frequencies, offering over 1400 user selectable frequencies to choose from. All the standard features of the ULXS4 receiver are present, in addition the ULXP4 is equipped with features that meet the demands of professionals. Additional features include TV channel display, frequency and volume locks, SCAN indicator, squelch indicator and receiving Antenna Indicators. The dual antenna design represents diversity technology, which provides optimum resistance against RF interference and drop-out. Dual internal receivers are set to the same frequency and are constantly vying for the strongest reception. The receiver features a balanced XLR output that is switchable between mic and line level signal as well as an unbalanced 1/4" Phone output. A multifunction LCD provides group and channel information, transmitter battery life, and more. Two 5-segment LED's provide audio and RF metering.

The ULX1 body-pack transmitter is light weight and portable featuring a belt-clip for use with camera and guitar straps, belts, waistbands etc. The transmitter also features over 1400 user selectable UHF frequencies and a comprehensive LCD displays group and channel information and more. An input attenuation switch allows 0dB and 20dB output. Adjustable audio gain control is provided and the transmitter boasts 8-9 hour battery life on a single 9V battery.

The ULX-2 handheld transmitter features the Shure SM58 cardioid capsule. Like the body-pack transmitter, the ULX-2 provides 1,400 user selectable frequencies, a comprehensive LCD display provides channel and frequency information, battery life and more. The cardioid polar pattern is effective against off-axis noise, causing feedback and unwanted ambient noise. The ULX-2 is powered with a standard 9V alkaline battery (included).
