VIDEO LINE CORRECTOR (BH73 BU)
VIDEO LINE CORRECTOR (BH73 BU)
The BH73BU unit has been designed to
compensate for losses in twisted pair video cables so that high quality
pictures may be transmitted over long distances.
Each channel has the following controls: Gain, Low
frequency lift, Medium frequency lift, High frequency lift 1-4, Input
Impedance and Input balance. These controls are all independently
adjustable.
Surge protection is fitted as standard to the input and
output of each
channel.
