The Zaxcom QRX100Q RF, audio and timecode receiver is a quantum leap in wireless transmission both to and from the video camera.



The Zaxcom QRX100Q RF, audio and timecode receiver is a quantum leap in wireless transmission both to and from the video camera. It can receive up to four channels of 100% digital audio from up to two Zaxcom stereo transmitters to take full advantage of the four discreet audio channels available in most of today’s video cameras. With add-on features to suit your needs and budget, the Zaxcom QRX100Q provides unprecedented flexibility in a broadcast ENG receiver.

All transmissions are free from intermodulation that limits the amount of channels that can be used together in the same physical location. The Zaxcom QRX100Q allows more channels to be used together than any other system. Up to 140 audio channels can fit in a 35Mhz frequency block utilizing Zaxcom stereo modulation and 500Khz transmitter spacing.

The QRX100Q outputs audio in both analog and AES digital formats. Two AES outputs connect directly to most 4 channel broadcast cameras. AES input is typically the only way to utilize the 4-channel capability of many cameras on the market today.

Digital modulation keeps the signal interference-free from noise that would add distortion to an analog ENG system. It is housed in a lightweight industry standard package providing optimum compatibility and functionality for broadcasters and freelancers alike.

Any combination of Zaxcom TRX series mono or stereo transmitters can be used with the QRX100Q. The TRX9xx features include no inter-modulation, built-in backup recording on Flash memory (Pat. Pend) and an internal IFB audio receiver. Zaxcom’s true digital stereo transmission uses half the bandwidth of traditional analog solutions.

A single QRX100Q mounted on the side of the camera is a complete solution for audio transmission to/from the camera, TRX900 bodypack remote control and timecode synchronization. Significant size, weight and power consumption reductions are to the camera operator’s benefit. To replicate the capability of one QRX100Q, up to 4 receivers, a time code generator and an IFB transmitter would need to be mounted on the camera.

The QRX100Q offers performance and features superior to one and two-channel slot-in type receivers that are only available for a limited number of broadcast cameras. Slot-in receivers do not have sufficient intermodulation and interference rejection to allow them to be used in difficult RF environments. The QRX100Q with its 500KHz minimum frequency spacing, total immunity to RF overload and digital dropout protection is the best choice for any environment.

The QRX100Q quickly attaches to any broadcast camera with an industry standard mounting kit.The externally mountable design also allows the QRX100Q to instantly connect any broadcast camera overcoming the compatibility issues of slot mounted receivers.
