Hi guys came accros this picture of a 10,000watt macro tech amp..
 
Is this a picture of a prototype? Or maybe a failed attemp by crown to build such a beast?
 
Must weigh a ton if a prototype does existShocked

seems it was intended for stadium use ... down into 0.5R   .. but otherwise, not particularly powerfu.. especially when you consider the 10,000 watts was only for a single cycle of 1khz .. was down to 6K for a 40ms burst .. RMS was probaly 3K  or so ...

I think I saw one of these driving a vibration test rig once ...

they were a full production item but presumably not many were sold, remember Crown, Amcron and AE Techron are the same company but AE T. specialise in medical equipment ie MRI scanner coil drivers- that's probably the genesis of this unit. Output current capability more impressive than voltage so works best on v. low impedance loads. 
8x PD1850's hanging off this thing would be saying plenty i reckon!

It's impressively large but the Crest 10001 is more impressive in terms of power output.

The Crown Macro-Tech 10,000 requires 3-Phase 208 volts in order to operate. Who is moving about with that type of voltage.

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.

So would your back tryiny to move it? I saw one of these at one of the plasa shows on the shuttlesound stand (display only)
it was huge, they said one was installed at of of the usa motor race tracks powering 64 bose 802's?

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.

I love stuff like this. Way over the top equipment that manufacturers simply wouldn't make now due to the cost issues. Some of the high end 'home' speaker systems Tannoy and JBL used to make were also just stupid.
Just look at some of the specs of this Crown monster, 80 output devices, gulp!

Looks like it should have its own gravity field.

The belchfire was a comedy datasheet production by crown, really quite funny for nerds such as myself

The MA10,000 is intended for running to very low impedance loads (eg a large impedance based paging system rather than 100v)
4 ohms is for wimps
