Audio interface with 10 outputs

[Octopulpo]

Hi everyone
I have a project where I need to connect my laptop to 10 different guitar amps.
My idea is to buy an audio interface with 10+ outputs (I don't really care about inputs)

For example, I found those :
https://www.thomann.de/gb/behringer_umc1820.htm (10x 6.3 mm jack line outputs (1 + 2 monitor output L/R))
https://www.thomann.de/gb/tascam_series_208i.htm (2 Balanced TRS main outputs with front level control + 6 Balanced TRS outputs + 2 Stereo headphone outputs)
https://www.thomann.de/gb/esi_u108_pre.htm (8 Balanced line outputs: 6.3 mm TRS + Stereo monitor outputs: 2x 6.3 mm jack + Headphone output: 6.3 mm jack)

My question is, with this kind of audio interface, can I send a different audio signal to each output channel at the same time? I guess(and hope) the answer is yes. But I really need to make sure about it before buying anything

Thanks in advance for your help!

You'll want to look at how the volume on all these outputs is being controlled, or else they may run out of sync in that regard. Also check the manual of the 208i on whether monitor and headphone output are truly independent.

Other than that this is mostly a software problem. You didn't say how you were intending to generate / play back audio or what OS we are talking about.

BTW, chances are you'll want to invest in 5 pcs. Behringer HD400 or similar as well, or else I suspect ground loop hell awaits. Connecting the input grounds of 10 guitar amps (IEC Class I, unbalanced input) together just seems like asking for trouble to me, with some uncertainty depending on what the source computer is.

Thanks for the reply.
Yeah, I didn't want to be too technical...
I'm using PureData on Linux. I already did the same thing for years but with a 4 output audio interface (2 stereo outputs). It works perfectly.
Basically my laptop reads some wave files and send them to the outputs of the audio interfaces.
I just want to make sure I can have 10 totally independent outputs, so I can send at the same time a different wave file to each output.
I know it's possible to redirect the wave files to each output of an audio interface, but I want to make sure those audio interfaces I sent as an example have 10 totally independent outputs.

This example : https://www.thomann.de/gb/tascam_series_208i.htm (2 Balanced TRS main outputs with front level control + 6 Balanced TRS outputs + 2 Stereo headphone outputs)
Does it mean I can get 10 different outputs? Are the 2 balanced main outputs separated to the stereo headphone outputs? Is there a way to know that?

And about some Behringer HD400 or equivalent, yeah, probably. With my current setting (basically 4 amps), it depends on the venue. Sometimes no hum at all, sometimes it's quite annoying.

If you allready have a 4 output audio interface, does it have adat out? if so a Behringer ada is a simpler/cheaper solution.

the mains+outs thing is something that allways confuse me, too. some have for example main out 1+2 and then line-outs numbered from 1-4. and the product page say 4 in/4 out. does it have 6 or 4 independed channels? lol. you have to actualy check the manual in those cases

now the UMC1820 does it right by numbering the outs from 1-10 insted of 1+2 and 1-8. so the answer is 10 channels
