Hi everyone!

I just finished building my soundsystem. I got everything from amps to crossovers etc.
But now I see the problem with the powersupply, since you can't just plug everything into the wall( i think?)

So how does this need to be done? Where do you get your electricity from and wich cables do you need?

Blessings !!  Heart

Weeelll - it depends on the current draw you need. A (standard) wall socket can actually power quite a big system without any problem, due to the nature of muzak - the fact that it (usually) contains quite a large dynamic range, ie, there are gaps for the supply (amps) to recover & recharge the PSU's (capacitors).

However, if you have several large bass amps, for example, they will require a better supply, in which case you need to turn to something more robust, like 16A/32A or 64A supplies, either single or 3 phase.

You are then looking at investing in a decent distribution unit - or something cheap & cheerfull like this:-

Why not? With a bigger system the total current draw can exceed the supply capacity of a single circuit but that just means you have to find more circuits to tap. The pros usually have a power distribution system where all power is tapped from a single high voltage/high current source and then split up into smaller circuits as required.

I think the original poster should say what amps he has and what he's running off them. Will give a lot more info for working out what is needed.

And how do you use such a thing? Where do you get your elektricity from then ?




I have a load of these down in my cellar generating all my power. Where do you get yours then??

Some sound systems are designed to run off 2 x 13a sockets.

I think that is a good format that is easy to use at many venues.

Obviously it's dependent on what you're running.  You may be able to run a rig off a couple of 13a wall sockets for a small event or run the same amps with more gear off multiple 16 or 32 amps for a much bigger one.  

Get a clamp meter, (these are cheap and really invaluable)  measure your  gear when running at actual levels for the music you're going to play and use data from real world measurements to drive your decision making.  Once you do this it'll be more clear what supply you can run it off. 

i suspect you'll be using less than you think.

Unless your familiar with electrics/electronics a clamp meter is useless, what would you clamp it to?
A simple domestic 13a plug in power meter is way more usefull for testing individual items and whole systems.
The original question is from someone who knows "nothing" about electrics (no crime ,we all start there), suguesting 32a this ,3 phase that ,or even just "amps" really will not help.
Honestly in this situation just use a 3metre 4/6 way to 13a plug  into a wall socket. when was that ever problem?   (oh and perhaps put plug in RCD on the list)
