TECHNOLOGY UPDATE - Crystal Vision ups the outputs on new distribution amplifiers


Crystal Vision has released two video distribution amplifiers for its new Vision frame system, the 3GDA-VF and VDA-VF. The 3GDA-VF is a video distribution amplifier with more outputs than the company has previously offered and includes remote control as standard. It can be configured as reclocking or non-reclocking and will distribute any digital video (3Gb/s, HD and SD) as well as being DVB-ASI compatible. It can also distribute MADI audio. The VDA-VF analogue video distribution amplifier has been designed to distribute SD black and burst or HD tri-level syncs reference, and can also be used to create multiple copies of analogue video. The 3GDA-VF is claimed to support more standards than any other Crystal Vision digital video DA, and can distribute 3Gb/s, HD, SD and DVB-ASI sources. It can also be used to distribute MADI (AES10) audio, allowing multiple channels of audio to be transported down a single coax cable while supporting the industry standard payload of 64 channels at a sampling rate of 48 kHz. 

With its main application the distribution of SD black and burst or HD tri-level syncs reference, the VDA-VF can also be used to distribute SD analogue composite or HD or SD analogue component video. Features include gain adjustments of +/-3dB in 0.1dB steps, a clamp and high quality equalisation which will correct distortion to the analogue signal caused by up to 300m of cable  length. Using standard BNCs, the 3GDA-VF provides six outputs from the VR20 single slot rear module and 12 outputs from the VR15 double slot rear module. Crystal Vision is also offering a Micro BNCs rear module for the first time (the VR16), which gives nine outputs in a single slot. Using the single slot VR18 with the VDA-VF gives five analogue outputs, with 12 outputs possible with the dual slot VR17. The VDA-VF additionally includes a loop-through of its differential input, which is independent of the VDA-VF and so allows the card to be removed without losing the looped-through source. Crystal Vision's managing director, Philip Scofield, said:“Updating our digital and analogue video distribution amplifiers for the fantastic Vision 3 frame has allowed us to introduce economic signal monitoring and control as well more outputs for what is still a fundamental part of broadcast systems.”
