Default Veldyne class D amp consumption?

Hello,

In the near future I'd like to buy a velodyne SPL 800 which has a 1000w classD amp.
Before I want to built a balanced transformer to feed my entire system.
I can't find the consumption of that kind of amplifier to estimate the VA rating of my balanced transformer...
Maybe the fuse rating could give me good indication?
If somebody knows or can estimate it...he'll be welcome!

Thanks a lot: David

What for?

Theoretically the power consumption could be 1100 W for a short time, but I never experienced 1000 W power output from SPL800, the in-built limiter limites it earlier.

In real life the average power won't exceed 100 W (otherwise the cabinet would burn out).

Idle power is about 10 W.

If you ask me, the power rating is nonimportant, only DC resistance matters. 1+1...2+2 ohm (primary+secondary) is OK (the lower the better).

Balanced Power from Equi=Tech

Yes I ask you! The DC resistance you're talking is about the balanced transformer?

I've found on the web an answer from a man wich gives the answer of a Velodyne technician: "Under 'normal' listening conditions in a 'normal' size room, I would estimate the wattage draw to be 100-400 watts. Keep in mind for every 3db increase of volume you double the power required, so going from normal to loud can increase the draw dramatically."


Thanks for your help
