1-. No. I assumed it does not work like that, reason why line level convertes exist.
2-. Yes, there is a headphone output, but this is only for 2 channel audio.

Line Level Converters... any measurements?

Done! Okay! Right! Thanks!
Sorry! Gotta go! Sort my socks!

I can see the irony on your comment, but I don't see any valid argument for it (plugin a speaker line level to another amplifier or using a HP output to drive another amplifier, both have no logic).
this thread is a train wreck
ive been in this OP's position... if you have a nice integrated amp but it does not have preouts but you want to keep the amp then how do you hook up a power amp? some amps you can route it out the tape loop but that's kludgey too
i'm reluctant to use voltage to rca line out converters... I know they exist and they may even work well but they dont sit well with me
there's a particular line of budget to midrange integrated amps made by a famous brand that for some reason, does not have preouts basically precluding any upgrade path.
their higher end line does have preouts... but you probably dont need it given they have good power anyway
so basically i avoid that brand's low end line...it sounds like a marketing limitation to me

Did you solve your issue? Are you using a line converter?

One thing you can do is use a budget AVR as HDMI switch and audio extractor to analog.
Yes.
No reason why, though. Passive voltage dividers are simply the fixed equivalent of the potentiometer that is in most preamps/integrated amps. You can build them or you can buy them and they work.
Main probem is you've already added much of the noise and distortion of the amp you are using as a preamp. Not much point then in feeding it to a "better" power amp, rather than just using the amplified signals as they are. At least that way you are not in additon adding the noise and distortion of the second (albeit better) amp.
Right. I wasn't advising the OP to do this but, rather, to do it this way if he must.

I used to avoid pre-outs on cheap integrateds after reading that some were basically useless because essentially they had poor gain and output impedance. Of course, they aren't "useless" but you need to know what they can drive to use them.
Sure enough, if you look here and in other forums you will find instances where people have upgraded first to difficult to drive speakers without checking, then a power amp to drive them because they had pre-outs on their old amp, then had to buy a new preamp anyway (or different power amp) because the pre-outs had insufficient gain.
If they can't be done properly at the price point, they aren't the most important features.
Hi dear community,
i'm interested to make that voltage divider to be able to input the speaker signals of my amps (a pioneer 85watts, teac 75watts and others) into my soundcard and mesure their frequency response but i don't have much knowledges on how to do this. Can someone guide me or show on pictures or video how to do this. How to connect the two resistors with the positive and negative wires of one channel on the amp? What resistors to use to get the job done? i want to test also all the amp that i will get in the future. Are their a risk of damaging my amp or audio equipments? I also plan of converting the output (speaker level) or passive subwoofers into line level to connect active speakers, so can i make with the voltage divider a converter than won't drop the volume much and what resistors will be needed in that case? Thanks in advance

Walmart has a variety. Just buy one. By the time you buy RCA jacks screw terminals and an enclosure to make
a proper device you’ve spent more than for one from Walmart. Not sure why the link above says what it says. It goes to Walmart.
Hi @Inge and welcome to the community!
Have you already searched through many posts on the subject matter... yet?

Before you go on and provide some basic details -- even the type of your sound card -- you may wish to learn what it takes to make worthwhile and accurate audio measurements.
As you can see, our ChiefFunOfficer seems to make some great/accurate measurements while he is sleep-walking, but by no-means it is to be taken as a simple endeavor.
I though about buying one but i was worrying about the signal being altered with all the components that i saw inside some of them and after reading here that a voltage divider is just a fixed potentiometer that don't degrade the sound and is done with only 2 resistors i though i could make it, 2 in series, connect jack cables and be set! It don't really need an enclosure, just an accurate sound to analyze my amps outputs and eventually use with a sub. Thanks for your answer, i will probably buy one if i can't make one quickly.Line Output Converter

I've done some research on google and youtube but only read this thread on this forum! i thought it was something simple to do like this
Voltage divider - Wikipedia
As for what values to use the article is a guide. One guy used 10k and 1.2k 1/2watt in a car forum.
you need to be careful though. There are many amps now that operate in BTL mode, so both speaker terminals are outputting half the signal each. In this case you don't want to connect the black terminal to the RCA ring / ground with the risk of the audio pixies sending up the emergency smoke signals.
Some stereo amps (especially the chip based amps) are using bridged mode for each stereo output.
