Default !! interesting ...

" ... Nice business to replace Crown by digital amplifier! ... a section for 200-400W DIY module! ..."

1) You probably should acquire your own commercially supported area here in the Vendor's Bazaar ( http://www.diyaudio.com/forums/forum...?s=&forumid=44 ) ... that way you can promote your company and projects and we can all continue these discussion and others related to your successes ... No offence, I personally am very, very interested in what you are doing as it is comparable to projects I am working on as well = commercial / pro-audio amplifiers. ( Self promotion is a good thing, but has another place in this blog than here in the DIY area(s). The costs here are incredibly reasonable considering the traffic volume and high level of the customer base. )

2) Since you indicate that you are working up a lower powered amp (200 to 400W), what kind of power supply(s) are you using? Digital / switching? Linear ? (Discussions about power supply design are always allowed here and elsewhere, as long as when the project is done and enters production, the promotion of the finished goods are place as above.)

Keep the faith

Hello FastEddy

Promotion on DIY dont give anything anyways, people are here to built and experiment, not to buy! I'm just there to help people in their project and to be keep in touch with new way to design. Lot of people have good idea that can improve performance or design cost, without copying the original idea. My product are mature, but production or design can always be improved! That the way, I think, technologie should evoluate.

The DIY project i projet to add to my web site will be a canceled order from big manufacturer ( I can't give any name here...). I have over 2000 unit of a 200 watts 8 ohms and 400W 4 ohms single channel module that only required a +/-65V power supply and a 0-15V 250Khz square wave to work. That was a module originaly designed for home cinema multi channel receiver. This is not a bullet proof module like the pro production amplifier, but should be enought for everyone that need to built/learn/modify a class-D amplifier for home purpose, or maybe a car amplifier with added heatsink. So my lose will be your gain!

Hmmmmm, so it's a one time deal is it? These are the 400W modules that you said you'd sell for 60$... canadian??

How is it exactly that once you've produced an order of 2000, they're still able to back out anyway? That's enough to ruin a guy

Default Oh boy ...

" ... I have over 2000 unit of a 200 watts 8 ohms and 400W 4 ohms single channel module that only required a +/-65V power supply ..."

... Do you have any junk/broken Crown amps ?? I'll buy some if the price is right

I got one that was broken, frisbeed the circuit board, and stuffed it with my own filter and amp modules .... worked out great!

(Looking for Crown XLR202 or equal = great chassis & transformer.)

Default blown amps

regarding all those blown amps - the Czech rave (mostly DIY) community has a simple cure - very very loud monitor speakers for the DJ :-)

Here is the states, the simple cure leads to DJ ear plugs ...

(You are right ... when setting up for an electric band in a smaller house, I always turn the monitors and the mains so that they feed back to the band through the stage mics ... that way they at least have to add EQ and cut the levels. I also make 'em sign off on a "you break it, you buy it" for the house PA.)

Nice way, but I just sold amplifier, install it and that's all. A sound man come to tune it at his (blowed!) hear, and after that, DJ do the rest of the job! And anyways, most of the time, they crank their monitor enought loud to override the sound of the mainroom, monitor amplifier fail and crank more the mainroom to have the same sound they was having with monitor...So I cant do nothing except look at the smoke in the speakers at the end of party, when it's not the speakon plug that melt....Anyways, people have to be responsible, specialy when they whant to have more and more....

That's why I have always a pair of ears plug in my pocket!
