Product Datasheet

The MDA 4V HD-SDI is a compact, one input, four output distribution amplifier for SDI and multi-rate HD-SDI serial digital video signals up to 2.97 Gbps. It automatically recognizes and adapts to common serial digital video signals that comply with SMPTE and ITU standards, including SMPTE 259M, 292M, and 424M, and ITU-R.BT601 and BT1120. The MDA 4V HD-SDI is ideal for use in broadcast and video production facilities, medical facilities, rental and staging, and other applications requiring a single serial digital video source to be sent to up to four displays at the same time.

The MDA 4V HD-SDI features automatic input equalization up to 500 feet (150 meters) for all SDI and 400 feet (120 meters) for all HD-SDI data rates from 19 Mbps to 2.97 Gbps. Output reclocking is provided for recognized SDI and HD-SDI standard data rates, including 270 Mbps, 1.485 Gbps, and 2.97 Gbps. A convenient front panel data rate indicator allows visual confirmation of input data rates for quick visual identification of the incoming digital video signal.

Housed in a rack-mountable 1U, one-quarter rack width metal enclosure, the MDA 4V HD-SDI is easily integrated into both new and existing AV systems, including broadcast and production facilities, command and control centers, and medical imaging facilities.
