I added a component to my system and a humming noise started coming from my cable tv. I added the Jensen Iso-Max and problem solved! Just like that. Simple to do and effective. Why the cable company doesn't know about this is beyond me. I highly recommend this product if you are experiencing cable noise.
Removed all 60hz hum out of my tv cable that was quite auidable because of the AV Receiver and external amplifiers using the same ground. Before that i had to disconnect the tv cable when I wasn't watching TV.
I had a significant hum introduced into my system by the cable feed into my cable box. Inserted the Iso-Max, problem solved. Everything now is as it should be!
