- Q: Right now, the cables behind my audio receiver are tangled beyond recognition. I need to organize them...How should I bundle my speaker wire to minimize RF and EM interference? I've heard that a quot;8-shapedbundle is good.Is there any truth to this claim? If so, explain.Thanks in advance!
- Keep power cables separate from Line Level cables(inputs, record outputs) and speaker cables away from Line Level cables. In other words keep the different types of cables away from each other. This also goes for FM antennas separate them all as well as possible. If you have HUM, you most likely have a cable that has a compromised (bad or going bad) Ground or loose connector. Bundling wires, even the same kind CAN induce hum, as it turnes it cable bundle into a coil (like a Guitar Pick-up). Try buying several extra good quality cables of each type, and switch them out one at a time, and you may find that one or more cable is compromised and is causing the trouble and throw it away! Make sure that the outlet the system is plugged into has a Good quality Surge Protector! not just an outlet strip< Make sure the circuit that is being used to power the system is not also carrying lights with dimmers, florescent lights, or any thing other than sound equipment. LIGHTS MOTORS CAUSE HUM! Also make sure that your not using several circuits to power several INTERCONNECTED items! ie: VCR, DVD, CD, PHONO on one circuit, and Receiver, TV, Cable Box on another (GROUND LOOP). Many times a moderately expensive Surge Protector will solve hum in a sound system(not a $10.00 one, but maybe $25.00 and up) I use a TRIPPLITE that cost more than $200.00, but it has been well worth it! ( I have a $50,000.00 studio sound system), as it not only filters noise that comes down the line, but it protects from surges spikes. (Duke Power calls them LINE VARIATIONS), but they will burn up delicate electronics in a heartbeat! If your wires are bundled, it will be hard to clean up the mess and noise! Even sharp bends in wires and cables will degrade the performance of even the best system, and make change outs (new DVD player) hatefull as well as put extra strain on the rest of the wires. and they wonder why they failed.
- Q: the power cable for my macbook is frayed and today started to spark. its currently unplugged, because of the sparking. i am trying to figure out if the power cable is covered under warrantee. the macbook is still covered under warrantee until August 2011Thanks in advance
- They do NOT fray like that without careless handling, which is NOT covered on warranty.
- Q: What are the causes of the power cable fire accident? How to prevent
- Notebook does not have the opportunity to DIY. The reasons are as follows: Notebook motherboard non-versatile motherboard, the shape of the motherboard, positioning holes, screw holes are not uniform standards, each manufacturer's motherboards are their own engineers and then open factory production model. Notebook shell corresponding to the interface location, type and screw hole location is with a specific motherboard supporting.
- Q: I'm trying to install a GeForce GTX 460. It came with a supplemental power supply cord, one end goes into the card, and there are 2 heads on the other end, and i can only find 1 place to plug in a single head into my power supply... When i turn the computer on the fan on the card turns on so i assume enough power is being given to the card, yet when i log in and put in the Installation disk, it says quot;not foundquot;... i already locked the card in, and i tried re adjusting the card multiple times but that doesn't do anything so i'm sure putting in the card incorrectly isn't the case. help! :(
- If your power supply doesn't have a PCIe power connecter then it is almost certainly not powerful enough to run the card. You need a better power supply. Next time read the requirements for the video card and make sure you know what it's saying. Did you even plug your monitor into the card after installing it? I said that if your POWER SUPPLY does not have a PCIe plug, then it's almost certainly not powerful enough to run that card. Adapters mean squat.
- Q: My stereo in my car is cutting out (powering off and on again) on high volumes. I'm trying to determine if it's my amp/sub-woofer or not. I switch off my amp with my remote power switch (the blue cable switch) and I still get the cut out. Is this conclusive enough to indicate that the problem is not with my amp/subwoofer?
- valuable it extremely is put in on your motorized vehicle in spite of the undeniable fact that it's not extremely valuable. The gadget bypasses the main significant and ignition exchange giving capacity to the motorized vehicle and starter. issue is that your motorized vehicle will initiate however if its in kit. think of of approximately status indoors your place and and wanting to warmth up your motorized vehicle. You grab your keys and hit the button. next subject you recognize is that your motorized vehicle has basically ran off by using itself and crashed into each element in its course as a results of certainty it became into in kit. Your coverage employer won't even pay for the wear and tear and tear as a results of certainty the education on the distant initiate says to no longer set up on education manual transmission autos. So valuable you could yet no you shouldn't
- Q: I just purchased and mounted my 52lcd and I cut holes to run the HDMI cables behind the wall. As I was snaking the power cable, I realized this might not be the best way. Is there anything I need to do (I only have basic 'contracting' skills) to keep my install fire code safe?
- The hole should be sealed for a fire stop.That little hole should not amount to anything.If you seal the hole and have a problem with the tv set you are really going to have problems removing the set for service.
- Q: I know they can control networks but what about cable, what is keeping cable channels from just showing hardcore pornography 24/7even showtime has a no bottom/no thrust/no rod rule.I don't have HBO so I don't know what they use, but still do we really need the FCC to censor its obvious that tv channels aren't desperate to put porn on the air so why do we need the FCC (other the the frequency adjustments for radio and what not)
- The FCC controls what is broadcast over the air waves. Cable TV is by subscription only, so if you don't like the programming you don't subscribe. Broadcast TV requires no subscription and is freely available to anyone who turns on a TV set. If the FCC were not there to control broadcast TV you would soon see porn popping up everywhere, since it is about the only thing that sells.
- Q: I originally tried to plug my US Xbox power cable through a converter, but it overloaded the cable and broke. Microsoft's advice to me was buy a Belgian Xbox, but they never answered my question about the compatability of a US Xbox 360 and a European Xbox 360 power cable.I appreciate any help I may get on this question.
- Euro is 220v to 250v or thereabouts, U.S. is only 110v. That's why your old PSU blew up. You needed to buy a step down voltage converter for avout 15 Euros or so. The Xbox PSU itself will handle the mains for whichever country it was designed for and convert the power to a DC voltage of 12v for any Xbox 360.
- Q: I have a USB powered external hard drive. The cable that came with it has to plug-ins for the PC. I know the fat one provides power so I use that one. I would like to know what the other skinny one is for.I have seen other people plug both in when using it and it worked fine for them. I am using just the fat one and it works fine for me. I would just like to know the reason for having both on a cable.
