3GDA-VF digital video distribution amplifier
What is it?
3G/HD/SD video and MADI audio distribution amplifier with signal reporting.
Reason to choose it...
The flexibility! You can configure it to be reclocking or non-reclocking, it will distribute any digital video (3Gb/s, HD and SD), it's DVB-ASI compatible and it's not even limited to video with its ability to distribute MADI audio. Plus the 3GDA-VF gives us more outputs per slot than we've ever had before on a digital DA - and your control system will know whether every DA has got an input thanks to the remote monitoring.
Ideal for...
Distributing signals in multi-standard big systems, where you want status information about your signal and need multiple outputs. See who's using our 3GDAs.

Distribute video signals in multi-standard environments
The 3GDA-VF is designed for the distribution of 3Gb/s, HD or SD sources. All outputs are DVB-ASI compatible – a useful feature given the wide use of ASI within the broadcast environment.
This ability to distribute so many different signals makes 3GDA-VF ideal for multi-standard environments or for engineers who want to 'future proof' their installations.
Get access to all your audio everywhere
The 3GDA-VF can additionally provide a convenient and inexpensive way to send all your audio channels to all your audio areas, without you having to worry about the details in advance.
Designed for transporting a large amount of audio as a block, MADI (AES10) is an audio signal format used for getting many channels of audio down a single coax cable, with these multiple AES streams packed together and sent with a higher data rate. MADI makes it easy to have a very flexible audio system by providing all your areas with ‘raw’ audio channels, not just a selected mix or subset. The 3GDA-VF can take in a MADI data stream and create up to 12 copies of this data stream which can then be sent to different places.
When distributing MADI, the 3GDA-VF supports the industry standard payload of 64 channels at a sampling rate of 48 kHz, with sampling rates up to 96 kHz also supported for those requiring fewer channels in return for the cleanest possible sound.
Choose your outputs
How many outputs do you need? With the 3GDA-VF, the number of outputs you get (and the number of frame slots it uses) is determined by which of the three rear modules you choose.
The 3GDA-VF gives more outputs per slot than Crystal Vision has ever offered before. Using standard BNCs you'll get six outputs with the single slot VR20 rear module and 12 outputs with the double slot VR15. For those happy using Micro BNCs, the VR16 rear module gives you nine outputs in a single slot. The ASI-compatible outputs are all non-inverted.
Choose reclocking or non-reclocking
There is no need to buy a different device for when you want to reclock or not reclock your signals. The 3GDA-VF includes user selectable reclocking and non-reclocking, which helps make it suitable for that wide range of signals.
The Reclocker mode has four settings – Auto, Bypass, MADI and DVB/ASI – which are selected remotely based on the input signal. ‘Auto’ will reclock SDI signals and automatically set the correct output slew rate (as SD or HD/3G). ‘Bypass’ will bypass the reclocker on SDI signals, with the output slew rate then manually set to SD or HD/3G to match the input signal. For MADI signals you should select ‘MADI’ to bypass the reclocker and automatically set the output slew rate to SD. Finally selecting ‘DVB/ASI’ for DVB-ASI signals will force the reclocker into a 270Mb/s mode and set the output slew rate to SD.
The 3GDA-VF will always choose an appropriate cable equaliser for the signal type, ensuring an SD cable length in excess of 250m with Belden 8281 or equivalent, and up to 140m for HD and 100m for 3Gb/s with Belden 1694A.
Control and monitor your signals
All control is done remotely. The control and monitoring options for the 3GDA-VF include an integrated control panel on the Vision frame, the VisionPanel remote control panel, our ASCII and JSON protocols, SNMP and the VisionWeb web browser control. Try the 3GDA-VF VisionWeb demo...
There is remote control of Reclocker mode and slew rate, while your broadcast control system will know whether every DA in the system has got an input thanks to the remote monitoring of input present and 3G/HD or SD signal. SNMP additionally allows alarms to be set on loss of input and change in signal type. The 3GDA-VF is therefore ideal for those seeking information about their signal, especially in big systems.
Save rack space
Fitting in the standard Vision frames (currently available in 3U size), the 3GDA-VF is a space-saving 96mm x 325mm card that sits in one frame slot - allowing up to 20 DAs in 3U, depending on the rear module fitted.
