Extron MDA4VHDSDI 4-Out 3G-SDI Distribution Amplifier

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.

Features:

Automatically adapts to SMPTE and ITU digital video standards for 3G-SDI, HD-SDI, and SDI
Supports data rates from 270 Mbps to 2.97 Gbps
