Longitudinal Hum Rejection

Using a Hum rejection unit will prevent and remove picture distortion caused by ground loop currents and mains pick up on the coax cable, and will prevent Hum Bars from appearing on the monitor screen.

Our Active solution gives amplification so there is no insertion loss and acts as a mid-range Line Corrector, correcting for signal losses to obtain better quality images on the monitor.

Hum Canceller and Line Corrector for Unbalanced (Coax) Cable

The BH186 unit is designed to cancel hum up to a maximum of 35V Pk-Pk and to correct for any signal loss in an unbalanced (coax) cable run, eliminating hum bars and enabling high quality pictures to be transmitted over long distances.

Hum Rejection Unit with Equalisation, Opto-Coupled

With the BH132 inserted into the cable run the incoming coaxial cable is isolated from the outgoing coaxial cable. This is achieved using an Opto-coupler in the circuitry.
