Zaxcom URX50 UHF IFB Receiver
Built for clean, critical listening on location, the Zaxcom URX50 is a UHF IFB receiver with a mono headphone output and a built-in speaker.
It works with any Zaxcom Digital Recording Wireless transmitter and has its full feature set with the TRXCL4 camera link. A tunable tracking front-end filter fights interference and extends range, two antennas add diversity, and operating distances can exceed 500 ft (152 m). The case is shock and corrosion resistant and easy to clean and disinfect.
Remote Setup
A Zaxcom GUI Bridge connected to a TRXCL4 sets up URX50 and URX100 receivers from any web browser. The sound team names each unit and chooses what it can hear: the script supervisor might get only the mix, while the director switches between the talent mics and the mix.
Monitoring and Voting
The URX50 receives mono and stereo signals and plays them through its headphone output, which drives headphones down to 16 ohms. The rear speaker lets the user listen without headphones. It can be set to switch when headphones are plugged in or removed, or locked off so users cannot turn it on.
IFB voting picks the best of up to three transmitters, covering a larger area than one transmitter can.
IFB Finder and Delay
IFB Finder plays a loud locator sound through the speaker to find a misplaced receiver. Up to six frames of programmable delay keep the sound in sync with picture on video monitors.
Power and Accessories
Three AA batteries run the URX50 for up to 11 hours on lithium, about 10 hours on NiMH, or about 7 hours on alkaline. With NiMH cells inside, receivers go straight into the optional dual drop-in charger at the end of the day.
The optional URXL1 lanyard adds volume control and a 3.5 mm jack for any headphones. The URX50-L covers 500 to 638 MHz, and the URX50-H covers 542 to 698 MHz.
