Hello everybody . I would like to ask a question about audio DACs. I would like to know if it is possible to insert the two low-pass and high-pass filters between the current output and the current / voltage converter. the first on one channel and the second on the other channel.
if it is possible to insert the two low-pass and high-pass filters between the current output and the current / voltage converter. the first on one channel and the second on the other channel.
I'm trying to figure out if it's possible to remove the crossover between amplifier and speakers.
I had thought of putting it in front of the amplifier but I don't think it's feasible because of the low input impedance of my amplifier.
remaining on the first question, is it possible to insert a resistance between the current output of the DAC and the filter in order to limit the current?
after doing this does the I / V converter that comes after work well?

I'm VERY sorry, but it's patently obvious that you don't have the slightest idea what you're doing
You 'can' put filters in front of amplifiers, and it's quite commonly done - BUT you then need separate amplifiers for each speaker (so one amp for bass speakers, one amp for tweeters - and one amp for midrange 'if used').
You also use active filters in such cases, not crude passive ones.
The DAC thing makes no sense at all, but if you give us some clue EXACTLY what you're trying to do (rather than how you're trying to do it), we can perhaps make some suggestions.
Hi.
I already knew what you said.
it serves no purpose to mortify people except to exalt their own ego. it was enough to say your opinion without attacking people.

No, that makes no sense.
A current output, outputs a specific current, whose value determines the signal level.
What's the purpose of adding a resistor to "limit the current", which would have the effect of changing the signal level?
If you want voltage than you use an I/V converter and do the filtering after that.
It would appear that you need to go back and restudy some basic circuit analysis of voltage and current.
