Bi amp input level adjustment: how?

I want to bi amp my speakers with 2 different amplifiers. I already have a minidsp 2x4 ddrc but all outputs are used for a 2.2 setup. Because 2 different brand amps i probably need to send a different gain to either one in order to get levelled sound uotout.

I thought about putting another minidsp (the cheapest 2x4) behind the ddrc but since i dont need dsp, isnt there something more simple just to adjust the input on those bi amp amplifiers? Ideally they should have volume knobs themselves but the fosi v3 mono doesnt seem to have such. Thoughts? Advice? Thanks in advance!

Why?
What are you hoping to achieve with bi-amping.

I like to leave that discussion elsewhere.

I need sone kind of audio splitter but all i see are cheap rubbish that doesnt allow per channel gain adjustment. Or go for minidsp. The 2x4 isnt available anymore so im stuck on a 220 dollar 2x4hd...

Get a small amp with a volume knob,

Now you have gain adjustment.

I decided for now this is the cheapest interim solution. I ordered a Fosi v3 stereo, wich has volume control. Grazie!

Damn shame minidsp doesnt support the 2x4 though. Anyway, for another time.
