The problem is that your household AC power is grounded at one point on your property, where the incoming cable coax is often grounded at another point, whether it's outdoors at the junction box or pole, or where it comes into your house (if the cable company inserted a grounding block and tied it to a different grounding rod that they installed outside your house, which isn't likely). Will the Mondial be ok with HDTV and On Demand which I have and use!Ĭlick to expand.Theoretically, yes. I put one on each one of my televisions, reduces hum bars also. Getting a flat frequency response from 2MHz – 1300MHz ensures no loss of signal quality and a great result. Why is this important? Well for starters if you plan on using digital cable, a cable modem, or on-demand services you better not get a cheap RF filter from the local electronics store as it will most likely filter out more than you bargained for. Jensen Transformers ( ) has been around for over 30 years and makes one of the best (MSRP $59.95) as it has a flat frequency response from 2MHz – 1300 MHz, spanning the VHF/FM/UHF/CATV spectrum. The most common, and easiest, solution is to add a Cable TV ground isolator. ![]() Total current draw is between 3.9 and 4.2 amps. Two KRK Active Monitors, each are Bi-Amped I have everything but the amp plugged into it. I can monitor the amperage usage with the Furman Power Conditioner. If the cable box had an optical toslink then I’d be ok.Ĭan I lift the ground from the receptacle so I don’t have to use some crappy ground lifting adapter? The only thing connecting the cable box to the system is a digital coaxial. Both will contaminate the 2-channel system with a hum if the system is grounded and if the cable TV is connected to the system. I also have the analog line outs from the Denon DVD Player going into the AVA Preamp. I have a preout signal for the Front R/L channels from the Pioneer to the AVA Preamp. They both want to be ungrounded so the entire system has to be ground lifted to avoid the hum. I’ve always had to lift the grounds on the sub woofers and powered speakers to avoid this type of ground hum but the AVA Preamp and SET amp are fussier. My Pioneer AV Receiver is Not grounded, its hard wired with a two wire cord. This is a Cable service problem? Can it be fixed? My last house was that way too and so is my friend’s apartment. Why the hell is the cable TV line not grounded properly, this is not the first time I’ve come across this problem. I tried lifting the ground to each separately I found they both need to be lifted to remove the noise. All the components go into a Furman power conditioner and the amp goes directly into the wall. A remedy was to use a ground lift on the power conditioner and amp. My only problem is a horrible ground hum with the cable TV coaxial touching the system in any way. My dedicated listening room is months away from being built and I just can’t stand not having a 2-channel system to listen too so I wired up both systems in my living room. The ground loop isolator terminates ground loop currents in a cable and blocks the hum and interference carried in the ground loop.I combined my Home Theater with my 2-channel system today it took all day but what else to do during a snow storm in the north east? This equipment interprets this interference as part of the video signal and displays it on the monitor as a rolling “hum bar”. The current flows through the shield of coaxial cable and it picks the interference up and carries it to the inputs of CCTV equipment. Because there is multiple ground paths, loops are formed in which current can flow. Installation of the Lemar Video Ground Loop Isolator rescues you from the irritation of tearing apart your setup as you search for the source of irritating signal disturbances such as those caused by loops or wiring laid too near power lines.Īlso provides for better surge protection, while convenience of installation means the Lemar Video Ground Loop Isolator is easily added to previously existing operations.Īn earth loop interference may occur when there is more that one ground or earth between two pieces of equipment. Our Video Ground Loop Isolator is a necessary part of every CCTV setup, providing improved security from troublesome ground loop distortion. ![]()
