Zaxcom STA150 Features



Zaxcom STA150 Features

The ​Zaxcom STA150 allows ENG audio professionals to transform an existing single-channel Zaxcom TRX900 or TRX900AA wireless transmitter into a two-channel transmitter for an instant sound bag-to-camera link. With all connections mounted on the side of the unit, the STA150 is designed specifically for use in sound bags to provide instant, on-the-go ease of use.

The ​Zaxcom STA150 stereo adaptor provides a balanced stereo audio input that eliminates ground loop problems. With a dedicated timecode input, the adaptor enables an exact match of audio recorded on the TRX and audio/video recorded on-camera by synchronizing the timecode generator inside the TRX unit and supporting automated loading of audio onto the TRX’s CompactFlash® memory card. The STA150 interface also features an output that can be used either as an audio monitor for playback from the memory card or as a timecode output to jam other devices. The STA150 includes an external power input for connection to a 12-volt external power source.

Zaxcom QRX100Q Features

The ​Zaxcom QRX100 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, ​Zaxcom QRX100 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 QRX100 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 ​Zaxcom QRX100 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 ​Zaxcom QRX100. 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 ​Zaxcom QRX100 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 QRX100, up to 4 receivers, a time code generator and an IFB transmitter would need to be mounted on the camera.

The QRX100 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 QRX100 with its 500KHz minimum frequency spacing, total immunity to RF overload and digital dropout protection is the best choice for any environment.

The ​Zaxcom QRX100 quickly attaches to any broadcast camera with an industry standard mounting kit.The externally mountable design also allows the QRX100 to instantly connect any broadcast camera overcoming the compatibility issues of slot mounted receivers.
