The Kramer VS-44HDxl can be used as a high performance 4x4 matrix switcher
or as a dual-link 2x2 switcher that lets you simultaneously route any of the inputs
to any or all of the outputs for all SDI video signals, using BNC connectors.
In particular, the
VS-44HDxl:
Supports up to 300m cable equalization (300m for SD 1 signals, 200m for
1.5GHz HD 2 signals, and 100m for 3GHz HD signals)
Operates up to 2.97Gbps – enabling it to be used for standard definition, high
definition and the new 3G high definition serial digital video signals
(SD/HD-SDI)
Is SMPTE 259M, 292M, 424M and 372M (for dual-link HD-SDI signals)
compliant and supports data rates of 270Mbps, 1483.5Mbps, 1485Mbps and
2970Mbps
Features reclocking and equalization on each input, the storing and
recalling of setups, and a TAKE button for the execution of multiple
switches all at once
Has selector buttons that automatically light up in different colors—green,
when the VS-44HDxl detects a ‘standard definition’ signal, or blue, when it
detects a ‘high definition’ signal
Features the ability to switch genlocked video signals according to timing of
the GENLOCK reference input. Switching according to the Bi-level or
Tri-level Genlock input according to SMPTE RP-168 3
