| Dedicated Line If your computer has an optical output, using that to your DAC could eliminate the need for a separate line for the computer, as there's no electrical connection through optical. 02-19-12: KbarkamianThe non linear switching power supply of the com... | |
| Dedicated Line Best way to go is separate dedicated lines for digital and analog equipment.Definitely for a home computer.... They put filthy hash back out on the AC line. Dedicated lines decouple the power supplies from one another.Digital equipment switching p... | |
| Shielding components from EMI/RFI... Help please Bryon,You might want to do some research on the archives of Tweakers' Asylum regarding the use of ferrous, magnetic, materials. There may be better ways to shield for EMI.Search shielding for EMIhttp://www.hottconsultants.com/pdf_files/ground.pdfh... | |
| IC Failure Touch one lead probe of the meter on the outer shell of one RCA plug, the other meter lead probe on the outer shell of the other RCA plug. You should read continuity.Do the same test on the center hot pin of the RCA plugs. You should read continui... | |
| Shielding components from EMI/RFI... Help please Almarg, I've always wondered about the code to use only one ground rod as well. I have never heard an explanation. 02-14-12: Sarcher30Sarcher30,There is no limit of the maximum number of grounding electrodes (ground rods), only the minimum require... | |
| Shielding components from EMI/RFI... Help please Neither of those scenarios seems applicable to what Bryon was doing with the second ground rod, assuming that the means of insulation between the Reclocker and the Sonos and their grounded enclosures is sufficient to withstand the voltage that wou... | |
| IC Failure More than likely the cable has an open connection.More than likely at one of the RCA male plug connectors.Bending the cable too sharply near the end can cause a connection to break free.If the ends are the type that can be disassembled, carefully ... | |
| Shielding components from EMI/RFI... Help please Bryoncunningham,What's with the dedicated ground rod buried under the house?The earth does not possess some mystical magical power that will suck, drain, RFI to it.What you have created is a great path for a lightning strike to follow. There is a ... | |

| Quick Dedicated Line Question? Yes.....That is if you want true dedicated circuits.Conductors that occupy the the same raceway will pick up common EMI/RFI interference.Also if you do go with a single conduit make sure the electrician does not give you 2 separate circuits, multi... | |
| Ungrounded power cord: Will I die? Herman,Sorry bout that.... I meant EI....If the shield is tied to the neutral and the neutral line is tied back to earth ground I'm not sure if the lack of the 3rd line makes a difference, but I don't think all countries use polarized plugs with t... | |
| Ungrounded power cord: Will I die? I was wrong and Elizabeth is right. The risk of death or injury from floating a ground is so low it is not a practical concern.I apologize for my previous comment.01-29-12: HermanSorry, to broad of a statement.If the OP's cord in question was used... | |
| Ungrounded power cord: Will I die? That is a universal 100-240 switching supply. Since outlets in many countries don't have a 3rd prong for ground it would have to be designed to not need one.01-28-12: Herman Herman,You could be right..... I checked the Net for an owners manual for... | |
| Ungrounded power cord: Will I die? Anyway, I have a 2-prong power cord with a 3-prong IEC female end that came with my Luxman amp. Eugene81That is just one of the problems with IEC connectors. For some reason here in the USA IEC connectors have next to no safety standard rules/requ... | |
| Isolation transformer - getting full, rated kva It's 220/440-120/240.01-04-12: NgjockeyNgjockey,If that is indeed the case, and each primary winding is wound for 220V and the secondary will output 120/240V then I would first bench test the xfmr. Good chance the voltage at his service electrical... |
