| To Float or not to Float... weebeesdad said: 09-16-2017 7:54pm Now that I have switched to a different power cord, there is no more buzzing or noise, and all grounding switches are set at "float". I would say that rules out an interconnect/s causing the buzzing problem. Au... | |
| To Float or not to Float... @weebeesdad ,No danger at all. The switch only lifts the audio circuit from the chassis ground.(The AC mains safety equipment ground) The AC mains safety equipment ground remains connected to the chassis at all times. In the event of a Hot to chas... | |

| To Float or not to Float... John Curl does not lift the AC mains safety equipment ground from the chassis on the JC 1 amp. "TECHNICALLY SPEAKING", page 14 3. Use the Ground switch on the JC 1 to eliminate most ground loops. This separates the JC 1’s signal input ground ... | |
| To Float or not to Float... georgehifi2,768 posts 09-14-2017 10:39pmAlso look at the fact that you can buy mains earth cheater adaptor plugs, which give you the option to float the earth of that piece of equ... | |
| To Float or not to Float... georgehifi2,768 posts 09-14-2017 10:08pmNo it’s you that doesn’t understand, as interconnect shields are kept at earth potential, some thorough a very low ohm resistor, if they weren... | |
| To Float or not to Float... georgehifi2,766 posts 09-14-2017 7:50pmYou clearly don’t know or understand.It still has to get a total system reference earth via the interconnect shield, if you disconnected that... | |
| To Float or not to Float... This is exactly how more than half the source equipment that use earth figure eight two pin mains cable get their earth reference, via the interconnect. IF the equipment is Class ll (Double Insulated) Listed that uses a two wire power cord and pl... | |
| To Float or not to Float... Correction: If a piece of audio equipment is Class ll rated the power cord will be two wire. In the US and Canada at least the NEMA 5-15P or 5-20P plug will be polarized so it can only plug into the wall receptacle in one direction. That should re... | |
| To Float or not to Float... georgehifi2,764 posts 09-13-2017 11:20pm What if all the AC powered audio equipment uses two pin mains plugs? Then this is lethal, there must be always a ground. Look at most C... | |

| To Float or not to Float... georgehifi2,763 posts 09-13-2017 5:08am This is extremely dangerous - interconnects are not intended to carry safety grounds. No it’s not as many sources have two pin mains plugs ... | |
| To Float or not to Float... I have a DeHavilland preamp which has a switch allowing one to "float" the ground. I’ve always used it in the "float" position, however recently, perhaps due to some connectivity issues with my interconnects, there is a small buzz emanating from ... | |
| Maestro faceplate - does it make a difference? I would buy a Porter Port before I bought Maestro duplex receptacle.The Maestro starts out as a Cooper BR20 duplex outlet. At Lowe’s, $3.47 https://www.audioasylum.com/messages/tweaks/202332/re-impressions-of-the-furutech-gtx-d-r-outlet-non...http... | |
| DC leakage from power amps @crazyeddy,What are you feeding the two amps with? I assume each amp has its’ own 120V 20 amp dedicated branch circuit. Roughly what is the distance, length, of the wiring from the electrical panel to the wall receptacle outlets? What are you usin... |
