The 3GDA-VF is a very flexible video distribution amplifier: it can be configured as reclocking or non-reclocking, it will distribute any digital video (3Gb/s, HD and SD) as well as being DVB-ASI compatible, and it is not even limited to video with its ability to distribute MADI audio. Including useful gain, equalisation and clamp adjustments, 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.
Supporting more standards than any other Crystal Vision digital video DA, the 3GDA-VF can distribute 3Gb/s, HD, SD and DVB-ASI sources – making it ideal for multi-standard environments. It can also be used to distribute MADI (AES10) audio, allowing many 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. The 3GDA-VF includes user selectable reclocking and non-reclocking.
The number of outputs available – the most important feature on a distribution amplifier – is based on the frame rear module selected. One of the advantages of the Vision frame system is that the extra length on the rear modules provides room for an extra connector compared to the Indigo system. This allows the 3GDA-VF and VDA-VF to offer the most outputs yet on a Crystal Vision video DA. 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.
Remote control and monitoring are included as standard on all the Vision products – particularly useful with broadcasters having fewer engineers manning their stations and therefore relying on a centralised control system to look after their equipment. Control options include the integrated control panel on the Vision frame, the VisionPanel remote control panel, SNMP and the VisionWeb Control web browser software.
