 Video Launch Amplifier and active Balun for conversion of unbalanced (coax) video signal to balanced (twisted-pair) signal.
Use as a Launch Amplifier to enhance
picture quality over longer transmission
distances and its installer-friendly design
has tool-less adjustable gain and high
frequency lift controls. Used at the monitor
end of the cable run it will function as a
Video Distribution Amplifier using the two
