About Shure ULXP124/BETA87C-X1

The Shure ULXP124/BETA87C-X1 Wireless Dual Mixed Microphone System provides professional wireless microphone solutions for broadcast, performances, conferences, houses of worship, schools and businesses. This combo-system includes two ULXP4 diversity receivers, a ULX1 bodypack transmitter and ULX2 handheld transmitter with a Shure Beta 87 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 and 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 LEDs provide audio and RF metering.

The ULX1 bodypack 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 0 dB and 20 dB output. Adjustable audio gain control is provided and the transmitter boasts 8-9 hour battery life on a single 9 V battery.

The ULX-2 handheld transmitter features the Shure Beta 87 cardioid capsule. Like the body-pack transmitter, the ULX-2 provides 1400 user selectable frequencies and a comprehensive LCD display provides channel and frequency information, battery life and more. The Shure Beta series microphones provide higher input levels than the SM series. The supercardioid polar pattern is effective against off-axis noise, causing feedback and unwanted ambient noise. The ULX-2 is powered with a standard 9 V alkaline battery (included).
