Receivers


ULXD4 Receiver – Single channel

One of three receivers in the ULX-D range, ULXD4 is a desktop, single channel receiver that can be mounted in a 1U, 19-inch format by using the included mounting bracket kit. The user can operate up to twenty-two compatible systems, in standard mode, or up to sixty-three compatible systems in high density mode – all within one 8MHz channel. Features such as over 120dB dynamic range and 24-bit/48kHz digital audio conversion, and interference detection and alert setup are included on the ULXD4 receiver. ‘Digital Predictive Switching Diversity’ aids smooth reception by silently switching to the best signal between receiving antenna, whilst the cleanest frequencies are automatically found, prioritised, and implemented when setting up a new channel.

The ULXD4’s front facing panel has visual aids to monitor RF on both channels A and B, audio input including overload, and menu/parameter setup via an LCD panel. Power button, control knob, menu buttons, and gain up/down control buttons are also located on the front facing panel, along with an infrared port for syncing with selected transmitter.

The rear facing panel of the receiver houses all audio and data connectivity including BNC connectors for antenna A and B, 15V DC power supply input, Ethernet port with associated LED for status, and audio output on balanced 3-pin XLR with mic/line level selection via switch, or 6.35mm jack line level output. The Ethernet port allows connection to Shure’s Wireless Workbench software with compatible computer, whilst AMX and Crestron control system compatibility is also standard. Rack mounting fixing is provided to fit 19-inch racking.
