Reconnect the subwoofer from its input to the receiver’s output and disconnect the offending feed from the outboard box or tuner (disconnect the cable before any splitters).If it does, the ground loop is probably coming in through your cable/satellite feed. Unplug the coaxial cable connected to your subwoofer and determine if the buzz vanishes. The main culprits are your subwoofer and cable or the satellite box feed at the entrance to your system.Once that was solved, no problems.Here’s a troubleshooting procedure to determine what the cause of your ground loop is and what you can do about it: I didn't realize this until I read about someone connecting a computer network between two buildings, and they had all sorts of 'gremlins' until they realized that it was a grounding issue between the two buildings.

So here, they would share the same grounding point, as long as they installed a grounding block on the incoming cable TV coax. At my house, I have a grounding rod for the electrical that is also located where any other cable runs come into the house (telephone, cable TV). If all the grounds shared the same grounding point, there should be no ground loop issues. The issue here is that there can actually be a difference in potential (voltage) between the two grounding points outdoors, which results in a 'loop'. 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. 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?
