About Shure ULXD124/85-J50

The Shure ULXD124/85-J50 Digital Wireless Combo Microphone System delivers transparent, 24-bit digital audio transmission, uncompromising audio clarity, extremely efficient RF performance, secure signal encryption and advanced recharging. This system includes the ULXD4 receiver, ULXD2 handheld transmitter with SM58 microphone capsule, ULXD1 bodypack and WL185 lavalier.

Both the transmitters and receiver are made of galvanized steel, making it rugged enough for any application. Its 24-bit/48 kHz digital audio fidelity, wide frequency response and 120 dB dynamic range result in an audio quality that's synonymous with wired microphones.

Its efficient and stable RF performance features up to 64 MHz overall tuning range, support for 14 active transmitters in one 6 MHz TV channel and 60 compatible channels on one frequency band. The ULX-D's optimized scanning automatically finds and deploys the cleanest frequencies available and interference detection alerts provide instant confirmation when interference is present.

The system's 256-bit signal encryption sends RF signal securely. Additional features include intelligent Shure battery circuitry for efficient battery charges, comprehensive LCD displays, XLR and 1/4" phone balanced outputs, Ethernet network capability much more.

Shure ULXD124/85-J50 Features

  • 24-Bit / 48 kHz digital audio delivers incredibly clear and accurate reproduction of the source material
