Combined Video Distribution Amplifier
and Video Line Corrector module. Comes factory installed when ordered with a BH220 universal

that guarantee a high quality picture over 1Km of RG59 coax. To assist during setup each channel
has LED indicators to advise when the correct signal amplitude of 1.0V peak to peak has been
achieved and when the video signal falls below -0.5V peak to peak.
