Re: What i discovered in my LLT build

With my power line sagging how much of an impact do you think it has?

as i have it currently connected as a 2Ohm load on the EP2500 bridged (yes i know they say not to do it but it works), and when i really push it my lights dim a good amount. is there any way to actually gauge how much wattage is actually being put out at the sagging stage?

Stop doing that. Don't connect that amp to a 2 ohm load. When the lights dim, it means you're dropping the voltage across any series resistance in the path from the service panel to the load. Do you want to start a fire?

It meets its specs with perfect conditions, but it won't meet its specs in 95% (or more) standard home installations.

Re: What i discovered in my LLT build

Those who care about raw amplifier power live in the UK where 3kW kettles are common. 250 Volts with 13Amp fuses.

Denmark is not quite so much fun. The 250 Volt 10Amp fuses don't really like 3kW kettles. Not if you turn anything else on at the same time.

Re: What i discovered in my LLT build

Come to Australia, 240V @ 15amps = 3600watts RMS
And nearly every domestic dwelling can be wired for 3-4 phase ([email protected]) :raped:

Just wish I had the gear to take advantage of it all.

If the supply over there is anything like here in Oz, that is the supply is an RMS value not peak, then the supply voltage (120Volts RMS) with a 15 amp fuse should be able to peak at 2500Watts for short periods. This means the amp can draw what it requires to supply 2000+ Watts (but only for short periods) without heavy reliance on its supply capacitors. Disclaimer, I know very little about the American power grid.

Re: What i discovered in my LLT build

Ordinary Danish homes are wired with three phases. They seem use all of them routinely! It was terrifying when I first came over here!

I only wanted to change an old ceiling rose dropwire and there were more cables in there than most AVRs have dangling off the back!
