It is the main reason why it never caught on in the States. There is a shop in New York that has one for display purposes.

Best Regards,
Actually any venue large enough to need that kind of sound would have 208 3phase. 3phase is fairly standard in commercial buildings. given its not a standard but most major venues should have it.  none the less an amp of that magnatude isnt intended for the average end user there built for installation.


In the 1980's, there wasn't a need for that type of voltage demand, as you would see today in the entertainment industry in the United States. With a lot of lighting being used today as oppose to 30 years ago as a means of effects, having 3 phase 208 volts was a rarity when this amplifier was introduced in the market.

The majority of audio professionals in the States are trying to get as much as they can on a 120-volt line, hence, the reason Crown & QSC only focuses on building 120-volt designs. There are only a few I know in the States (myself included) that operate their MA 5000vz amplifiers on 240 volts much less 208 single-phase. However the majority of users are operating those amplifiers on a 120-volt line source despite, having the ability to perform better on higher voltage.

Best Regards,

The standard system installed here in the USA for small buildings and residences is 240V 60 hz single phase with a center taped neutral. either end of the phase to center is 120V and from one end of the coil to the other is 240V. Which messes people up because they think that its actually 2 phases when in reality its just pseudo 2phase system.

I not sure any members will remember this,it was pre-speakerplans days,there was three of these badged as AE Techron on ebay as a job lot about 5years ago,apparently they had been removed from some government testing installation,but yes,they were deffinately 3-phase...all three together went for about £800....they must have cost a fortune new.
Be seeing you.
