3 Overview

The VM-20HDDual 1:10 HD/SD - SDI Distribution Amplifier is a high performance dual channel distribution amplifier for SDI (SMPTE 259M and SMPTE 344M) and HD-SDI (SMPTE 292M) signals. It will take one input per channel, provide reclocking and equalization and distribute each signal to 10 outputs, using BNC connectors.

In particular, the VM-20HD:

￿Can be configured as a 1:20 DA

￿Has an active loop BNC connector on each channel, for cascading additional units

￿Has a video bandwidth of 1.485Gbps that allows it to be used for standard definition and high definition serial digital video signals (SD/HD-SDI)

￿Is SMPTE 259M, 292M and 344M compliant

￿Supports data rates of 270, 1483.5, and 1485Mbps

￿Provides automatic, multi-rate, equalization and reclocking for losses typical with long runs of 75￿ co-axial cable

￿Has HD and SD output indication LEDs for each channel

To achieve the best performance:

￿Connect only good quality connection cables, thus avoiding interference, deterioration in signal quality due to poor matching, and elevated noise- levels (often associated with low quality cables)

￿Avoid interference from neighboring electrical appliances and position your Kramer VM-20HDaway from moisture, excessive sunlight and dust
