Zaxcom URX50 UHF Wireless Beltpack Receiver

The Zaxcom URX50 is a UHF IFB audio receiver. It’s designed to give you the cleanest sounding IFB audio you’ve ever heard. Perfect for critical listening on location, everyone on set will hear the difference!

Its rugged construction with nylon-filled material gives the case resistance to shock and pressure with the additional feature of being corrosion resistant. The case is also easy to clean and disinfect for the safety of everyone.

Wireless Remote Control Setup

A web-based remote control GUI can wirelessly set up and control the URX50s and URX100s. To use it, all you’ll need is a Zaxcom GUI Bridge connected to a TRXCL4. It’s extremely intuitive and can be used on any device with a web browser on it, you just type in the IP address and you’re good to go! The GUI controls things like naming your units and setting up channels that can be monitored by a URX. For example, you can let your script supervisor only listen to your cart mix, but you can allow the director to toggle between each of the talent mics and your mix if you want to. You have full control without ever having to be near to or touch the receiver once handed off.

Connectivity

The URX50 was designed to work with the Zaxcom TRXCL4 transmitter for full functionality, but it’s compatible with any Zaxcom Digital Recording Wireless transmitter. The UHF diversity receiver utilizes a tunable tracking front-end filter to combat interference and extend range. Digital dropout protection ensures excellent range and audio fidelity. Two built-in diversity antennas provide additional dropout resistance. Operating distances can easily exceed 500 feet (152 m).

URX50 can take advantage of IFB voting, where it automatically selects reception from up to 3 separate transmitters spaced apart in a larger coverage area than can normally be obtained with reception from a single transmitter.

Monitoring Options

The URX50 has a mono headphone output and receives mono and stereo signals. Each unit can be remote programmed for individual users to monitor selected audio at the control of the sound department.

A high fidelity speaker on the rear of the unit for applications where monitoring without headphones is necessary. The unit can be programed so the speaker function can be enabled or disabled if the headphone is plugged in or removed. If this makes you nervous the function can be disabled so the users can’t activate it.

The high SPL output headphone driver is ideal for noisy locations and it can drive headphones with as low as 16 ohms of impedance. Volume can be adjusted using the front push buttons or with the URX1 Lanyard.
