Benefits to Bi Amping or Bi Wiring

As Gene said lets "Do the math". I looked in my curciut breaker and I have a 100 amp breaker on my 220v stove.

If you hooked up your receiver to that outlet, it will quickly become your stove if you turn the volume up high enough and use forks as your speaker loads

I'm not hooking anything up to that outlet. I was thinking out loud why some CE manufacturer did not make an amp/reciever with power supply, caps, and the rest specifically designed to accept 220V 100A.


I'm trying to get 30hz to 170 decibels in my 200,000sq foot warehouse

B/C the amps power supply would have to way about 200lbs and if it ever managed to deliver full power to any particular speaker, it would instantly melt the voice coils.

This discussion has me thinking. What type of gear is used in commercial setting like the huge outdoor theaters? What type of voltage/current flows through the amps and drivers?

I agree, as I mentioned to him before, even at the same current rating, a 240V (primary side voltage) transformer will be much bigger and heavier than a 120V one. For a 240V primary at 100A ampacity, that's 24 kVA. The transformer alone probably weights 200 lbs and cost $2,000 or more.

Sound Reinforcement is an entirely different animal. They use multiple large high efficient, controlled dispersion horn arrays with very powerful and high efficient switching amps. The end result is HUGE SPL with fidelity NOT being a primary concern.

Crown had an amplifier that required a 3-phase connection, the MacroTech 10000. It's a 10KW beast designed to power arena-wide arrays of looudspeakers, such as for grandstands at a raceway.

" The ultimate amplifier, MA10000, provides 10,000 watts of power. First application, to provide power for 465 speakers at the Indianapolis 500 Motor Speedway."

What a beast that was!
