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. ĭC Block on center conductor protects electronic equipment from hazardous voltages and electrical transients.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? Isolates coaxial cable's shield, prereventing unwanted ground loop current on the shield of the cable, which can cause noise and degrade picture quality. It also is environmentally sealed to prevent ingress of moisture and humidity that has been shown to introduce CPD to a subscriber's premise drop. The metallic housing of the Viewsonics VSIS-EU coaxial ground isolator provides adequate EMI shielding. The isolator allows cable signals above 100Hz to pass regardless of whether a ground differential exists between the two connecting points. The Viewsonics VSIS-EU creates an electrical open on BOTH the center conductor and the outside shield, designed to work from 0-100Hz (DC current and AC current frequencies). If the re-work of the cable system's ground connections and establishing solid ground points in your cable system does not resolve these problems, then a Viewsonics Ground Isolator is the most reliable way to fix it. The result of a ground loop is audio hum and/or horizontal bars in the TV picture. This is actually quite common in home cable systems, even those that are well designed. When two or more devices are connected to a common ground through different paths, ground path noise or a ground loop can occur. Viewsonics Ground Loop Isolator (VSIS-EU): The Viewsonics VSIS-EU Ground Isolator is used to eliminate the hum and horizontal bars caused by ground loops.
