cheap amp + high power

That is not a DSP unit, it is purely analogue xo, not bad in itself it is only that just about any sort of DSP adds a lot more value than simple filters.



I did not think you were a complete beginner, it can be a journey to delve into PA standards and DSP. Having made a comparable transition myself, I would like you to know that any kind of cheap measurement microphone and a half decent DSP setup will help you increase understanding and be a much more flexible solution.
And also: balanced signal interconnects and speakon exists for a reason, it may even end up costing less money.

Edit:
Some of the units you list are a bit pricey compared to what I would consider. What sort of amps are you looking at locally?
Do you have any sort of budget for amplifiers and filters?

Kaffimann,

I now found a package of used stuff that seems dement. What do you think about this?

Amp: t.amp TSA4-700 https://www.thomann.de/se/the_tamp_tsa_4700.htm
Xo: t.amp XO 231


The seller wanted me to make an offer on it

found two used amps
bose entero 4500
4*400/500w 8/4 ohm
2*1000w 4/8 ohm



bose entero 4700
2*1400w 8 ohm
4*600/700w 8/4 ohm

what are these worth? decent stuff but 20 years old with phoenix output instead of speakon, no ground

...but i have the option of going with 230v amps since i already have a generator laying around

Before you go too far down this route, are you confident that your spare generator is sufficiently capable? A crude waveform might (perhaps) work better with a class-D amp than some other types, but there would still be quite heavy peak loads demanded; many undersized/cheaper generators (with an apparently high enough rating) would experience voltage-sag and waveform degradation unless they have significant headroom. If their peak current is limited, they could even cut-out (or burn out).

This is just a (hopefully useful) question. You may already be aware of this and be confident in your generator. But if not, the ratings of generators are more complicated than the ratings of DC batteries.

Both can work, and do. But perhaps in a truly mobile situation wanting down to 1ohm capability on a budget, I'd guess that big DC batteries with enough alternator (or generator) power to keep them charged might be the simplest answer.
