Review the contents of this user manual Use Kramer high-performance, high-resolution cables

2.1 Achieving the Best Performance

To achieve the best performance:
Use only good quality connection cables to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VM−2HDxl away from moisture, excessive sunlight
and dust

3 Overview

The VM−2HDxl is a high−performance distribution amplifier for 3G HD−SDI signals. The unit takes one input, provides reclocking and equalization and distributes the signal to two identical outputs.
In particular, the VM-2HDxl features:
Cable equalization up to 300m
300m for SD signals; 200m for 1.5GHz HD signals; 100m for 3GHz HD signals (measured with Kramer BC-1X 1 Coax RG-6 Super High-Resolution Cable).
One input and two identical outputs on BNC connectors A data rate of up to 3Gbps, that enables it to be used for standard definition, high
definition and the 3G high definition serial digital video signals (SDI, HD-SDI and 3G HD-SDI)
HDTV compatibility Passing of digital information (embedded audio, Teletext, time code and so
on) during the blanking period
SMPTE 292M, 259M, 344M and 424M compliant with data rates of
270Mbps, 540Mbps, 1483.5Mbps, 1485Mbps and 2970Mbps

3.1 Defining the VM-2HDxl

Automatic, multi-rate, equalization and reclocking for losses typical with long
runs of 75 co-axial cable up to 300m
