2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
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
