Frequently Asked Questions - VDA-104-3GS-2 Marshall Electronics
What is the VDA-104-3GS-2 used for?
The VDA-104-3GS-2 is a 1x4 3G-SDI distribution amplifier used to distribute a single SDI video signal to four outputs with signal reclocking and equalization.
What video formats does it support?
It supports 3G-SDI (up to 1080p60), HD-SDI (720p, 1080i), and SD-SDI (NTSC/PAL) formats.
How do I connect the device?
Connect your SDI source to the INPUT BNC connector. Connect up to four SDI devices to the OUTPUT 1-4 connectors. Power the unit with the included 12V DC adapter.
What does the LED indicator mean?
The Power LED lights when powered. The Input LED lights when a valid SDI signal is detected. Output LEDs (if any) indicate signal presence on each output.
What is the maximum cable length?
With automatic equalization, the VDA-104-3GS-2 can drive up to 100 meters of Belden 1694A cable at 3G-SDI (2.97 Gbps).
Can I daisy-chain multiple units?
Yes, you can connect one output of the first unit to the input of a second unit to distribute the signal further, as long as cable lengths and signal integrity are maintained.
How do I mount the unit?
The unit can be placed on a desk or mounted in a rack using an optional rack-mount bracket (not included). It occupies half a rack width.
What should I do if there is no output signal?
Check that the Power LED is on. Ensure the source is outputting a valid SDI signal and that the cable is securely connected. Verify that the input LED is illuminated. If not, test with a different source or cable.
Is the device compatible with 12G-SDI?
No, the VDA-104-3GS-2 supports up to 3G-SDI only. For 12G-SDI, consider a different model.
How do I clean the device?
Use a soft, dry cloth to wipe the exterior. Do not use liquids or sprays as they may damage the electronics.
