The URX100 UHF receiver by Zaxcom is a multipurpose receiver capable of acting as a camera hop, an IFB with walkie interface, or standalone IFB receiver with time code view and delay.
Any Zaxcom digital recording wireless transmitter will work with the URX100. As a UHF diversity receiver, it utilizes Zaxcom’s tunable tracking front end filter to combat interference and extend range. Two antennas – one internal, the other external – offer dropout resistance while receiving audio. Audio is encrypted to maximize privacy and operating distances can exceed 500 feet.
The URX100 is a low-cost solution for getting audio and timecode to camera. There are two modes of operation: stereo audio output or mono audio output with SMPTE timecode that is sub-frame accurate. Stereo audio or balanced mono audio is output from the 3.5mm headphone jack. SMTPE timecode and mono unbalanced audio is output from the auxiliary TA5 connector.
The URX100 can be connected to the remote speaker/mic port of a walkie talkie. You can route the walkie talkie audio left, right or center by the URX100 and/or mix the walkie audio with the URX100 receiver audio. This configuration allows both the URX100 and walkie talkie audio to be heard at the same time with a single pair of headphones when using the URXL1 lanyard (sold separately). The URX100 is compatible with the most common brands of walkies.
As an IFB receiver, you can listen to mono or stereo audio and view time code on the OLED display. A programmable delay of up to six frames allows for synchronization with video village. When using the optional URXL1 lanyard, you can listen to both the IFB audio and walkie talkie audio, talk back using the built-in URXL1 microphone, and adjust the volume.
The URX100 can also monitor a stereo signal or route the audio to left, right and both ears as a mono mix. The stereo signal can be selected at the URX100 so that a boom operator can monitor one of two transmitted channels such as a public IFB feed and a private communication channel. This monitored audio can also be combined with the audio from a connected walkie with left, right or center routing.
The URX100 is a lightweight 4.5 oz (127 g). A front panel provides controls for channel selection and volume adjustment and a top screen displays channel names.
Three lithium AA batteries will provide up to 10 hours of runtime while alkaline will last up to 8 hours.
Some versions of this wireless microphone device may operate in portions of the 617-652 MHz or 663-698 MHz frequencies. Beginning in 2017, these frequencies are being transitioned by the Federal Communications Commission (FCC) to the 600 MHz service to meet increasing demand for wireless broadband services. Users of this device must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies. For more information, visit the FCC’s wireless microphone website at www.fcc.gov/wireless-microphones-guide or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.
