3 Overview
The Kramer VP-2L is a high performance line amplifier for computer
graphics video signals (up to UXGA) and HD signals. It accepts an input on
an HD15 connector and provides a buffered output, also on an HD15
connector.
In particular, the VP-2L UXGA Line Amplifier:
Has a resolution of up to UXGA, ensuring that it remains transparent
even in the most critical applications
Features trimmers for output level and cable equalization, ID Bit
control, and a LED power indicator
Is housed in a small enclosure and is 5VDC fed.
Achieving the best performance means:
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)
Avoiding interference from neighboring electrical appliances and
positioning your VP-2L away from moisture, excessive sunlight and
dust
