With the Marshall Electronics VDA-104-3GS 1x4 3G/HD/SD-SDI Reclocking Distribution Amplifier, you can take a single SDI signal and send it out to up to four devices simultaneously. SD, HD, and 3G-SDI standards are supported, and the input standard is automatically detected. Each SDI output is separately reclocked and buffered, ensuring signal fidelity over long cable runs. Easy-to-read LED status indicator lights denote the converter's current status. The integrated mounting brackets on both sides of the unit can be used for semi-permanent installation.
