ñ
ñ
ñ
Accepts one input and distributes the signal to 4 identical outputs using
BNC connectors
Has a video bandwidth of 1.485GHz that allows it to be used for standard
definition and high definition serial digital video signals (SD/HD-SDI)
Is SMPTE 292M, 259M and 344M compliant and supports data rates of
143, 177, 270, 360, 540, 1483.5, 1485Mb/sec
Provides automatic, multi-rate, equalization and reclocking for losses
typical with long runs of 75W co-axial cable
Has LOCK, HD and SD output indication LEDs
Achieving the best performance means:
ñ
Connecting 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)
ñ
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality and positioning your Kramer VM-4HD
away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit1.
