Hi there.
I'm interested in building PA speakers.
I'm stuck on the cost of plate amplifiers. Hypex looks very good, but too expensive for my requirements.
My question is - how do companies like Yamaha and Mackie make or source their amplifiers for their PA speakers in the £300-£600 range (like Mackie SRM450 or Yamaha DXR15)?
Clearly, they spend no more than £100-250 per amplifier / power supply / crossover combination, otherwise they would be making a loss.
So, is it common for these manufacturers to actually build from scratch.. Or do they buy from some other source? The only example I know of where I have any clue is actually my Alto Black series speakers- the plate amplifiers are clearly made by Dayton Audio - they are identical in appearance to their PPA800DSP.
Would their be any future in me buying Sure Electronics amp modules and SMPS'?
Any clues or insights appreciated.

The large Companies you mention make their own or worst case have custom ones made by some specialized OEM factory to their specs, in large quantities and for a very competitive cost.
And why did you choose expensive Hypex as an example?
Industry standard ICE Power, used by many Musical Instrument amplifier manufacturers, including Fender and many more, are very good and carry a more reasonable price tag.
For example: Hypex 500W costs 450 Euro ; ICE Power 125ASX2, capable of 450W RMS costs U$125 to the public in single units, I bet Fender pays some U$60 for them, by the container load.
There must be an OEM supplier which manufactures *both* Alto and Dayton amps, and probably many more.

Can I ask-
Is it worth finding a cheaper switch mode power supply, or just going with the ICE SMPS?
Just I have a particular purpose for which I need a 100-200W amplifier, and the lowest power SMPS that ICE do appears to be 400W.
Thanks

There are several PA amp and plate amplifiers with modules from Pascal Audio. Ie Monacor has (or had) such amps, can't remember other brands though.
Gisen are an OEM for power amps: Best Stereo Amplifier & Power Amplifier Manufacturer | Gisen
they will produce an amplifier with a custom faceplate if you want it. We have a couple of their highest power class-D model for a few weeks. So far the only issue we have found is that the UK 13A plug supplied had a wire soldered across the fuse, presumably because this amplifier requires a 32A feed.
Sanway are another OEM that does plate amplifiers but I have no experience of them: https://www.china-sanway.com/Plate-Amplifier-pl44020.html
Yamaha will almost certainly manufacture their own amplifier as they have the internal expertise.

The 125ASX2 has an integrated power supply so you don't need to add anything.
The equivalent of the 125ASX2 can also be found at Hypex, the NC122MP, and it costs only €112. It also has an integrated power supply.
You also have the NC500MP that delivers 500W for €139.
Hi florentg, where can you buy the nc122mp module? I have been looking around, but could not find a dealer. Next week, I am in the Netherlands, if that helps (i.e. some local dealer). Thanks, Michael
Hypex and ICE, no serviceable. It need completly module replacement. ICE custom their chip.
I suggest you make your own design. There are plenty free class D available.

I just had a look recently in the d&b audiotechnik D20 amplifier which is rated at 4*1600 Watts.
I'm 99.99% pretty sure, that the amplifier module inside this D20 amp is an OEM version of the Powersoft Digimod modules. Not officially listed at powersoft, but the controller-card module looks 1:1 the same as on the other Digimod amps.

Also have a look on LinkedIn -> there are a couple of freelance hardware engineer specialists focusing on Class-D audio and/or DSP stuff.
If you check them, you will see that those guys have references at almost all well known brands in the pro-audio market.
All Class-D stuff up to approx. 1000 Watts at 4 ohms is already "commodity" stuff and usually handled by Infineon's IRS controller chips. There are a lot of companies having this knowledge already in house.
