VIDEO LINE CORRECTOR (BH74BB)
The BH74BB has
been designed as a repeater unit for use with twisted pair cables so
that high quality pictures may be transmitted over long distances.
Suitable for colour or monochrome video signals the unit will equalise
the incoming cable losses to a maximum of 45dB at 5MHz. The Gain, Low
frequency lift, Medium frequency lift, High frequency lift, Input
impedance and Input/output balance are all independently adjustable.
Internal surge protection is fitted as standard on all units.
