, så undrer det mig bare, at strømmen ikke, som jeg ser det, ikke tages alvorligt i studier. Jo bedre lyd i studiet, jo nemmere må det være at arbejde med.
Tas ikke alvorlig?
There is very little published regarding power systems for professional audio systems and installations & resolving problems by Julius Newell.

In all cases and in every aspect our friend is a low impedance source.
The principle requirements for a successful audio system power installation simply relies on a good very low impedance power source, adequate peak current delivery, and a very low impedance reference ground between all items of equipment.
Once we have found a good low impedance source we need to bring it to us, it’s no good finding a low impedance source and turning it into a high impedance source by using thin cables.
In cases where proper installation has not been possible, where other services are sharing the lines or where there simply isn’t the possibility of demanding a clean source one possible method of resolving issues are various types of power line conditioner. This is often a hit and miss affair, if we are lucky and the issue is minor we may see a reduction in HF noise or distortion artefacts. The reason many filter boxes fail to resolve such issues is simply that they require a solid Neutral and Ground path to filter (short) the interference down to.
A very poor (for audio) line is easily able to pass an electrical safety test, and so long as the line passes the test the electrical installer sees their job as finished and done. But when we see a pair of identical radial lines from the same board reading different loop impedances we know there is something that is not optimum, even if it does meet the required pass value.
No electrician will feel motivated to pull their install apart looking for a 0.25Ω difference between two lines that pass by over 1Ω unless they have to,
Fineste studio som noen gang er laget?
The most lavish recording facility ever built is not in London, New York or LA, but a remote part of South Africa. We trace the extraordinary story of BOP Studios.

the console and studio wiring is with Van den Hul silver cables: Studio 3 alone employs 11km of wiring!

. So we went though and we listened to a whole bunch of XLR connectors, we listened to 20 different audio cables, because I needed 23 kilometers of cable to make our own patch bay and rewire everything in the studio… all the outboard gear and the machinery. We listened to 20 different cables. We directionalized them all first, of course. Every cable sounds different in a different direction. It’s small, but it sounds different. And actually, the most amazing thing we discovered was when we listened to our technical earth cables, which we have going into copper rods in the riverbank. Our technical earth cables are just a heavy duty, high quality, regular, copper thick-sheathed cable. We’d been recommended to try this multi strand thinner cable, which had been woven like some of our audio cables.
We went though all these regular cables that people wire studios up with that are fairly inexpensive. And the one that we ended up using was made by - this is for the 23 kilometers of cabling - was made by a high end hi-fi audio manufacturer called Van den Hul from Holland. I’d actually later found out they had originally designed this cable for the Philips Studio in Holland
