Video Line Corrector (Opto Coupler) (BH73UU)

bh73uuThe BH73UU has been designed to compensate for losses in coaxial
video cables so that high quality pictures may be transmitted over long
distances.

Each channel is fitted with an opto-coupled circuit to provide an optical
pathway for the video signal.

This isolation of the input and output signals prevents the appearance
of Hum Bars on the video monitor in situations where circulating earth
currents in the cable are causing a problem.

The signal input and output of each channel are fitted with surge protection as standard.
