Zaxcom’s QRX100 broadcast ENG receiver is now shipping worldwide.
Aimed at television production operations making use of the audio channels available from current video cameras, the unit supports up to four channels of digital audio, from two Zaxcom stereo transmitters.
‘A single QRX100 mounted to the side of a camera provides complete audio transmission to and from the camera, remote control of our Zaxcom TRX series of transmitters and timecode synchronisation,’ says Zaxcom president, Glenn Sanders. ‘Replicating the capabilities of just one QRX100 would otherwise require four receivers, a time code generator and an IFB transmitter. The unit significantly reduces size, weight and power consumption requirements, all to the benefit of the camera operator.’
The QRX100 receives four channels of digital audio from up to two transmitters and outputs in both analogue and AES digital formats. The lightweight, industry-standard packaging of the QRX100 attaches quickly to any broadcast camera. All transmissions from the QRX100 are digitally modulated, keeping signals free from the interference and noise that would normally cause distortion in an analogue wireless system. Because all transmissions are free from intermodulation, the QRX100 allows more channels to be used together — up to 140 audio channels in a 35MHz frequency block.
‘The QRX100 offers the performance and features of one- and two-channel slot-in-style receivers, without the limitations of such systems,’ adds Sanders. ‘While slot-in receivers are available for a limited number of camera models and do not have sufficient intermodulation or interference rejection to make them suitable for use in difficult RF environments, the QRX100 resolves these issues with 500kHz minimum spacing, total immunity to RF overload, and digital dropout protection.’
