Default Headphones output to line level

Hi everyone!

I need to connect a micro-hifi system to a mono amp, but the micro-hifi only has speakers and headphone out.
I took a look at the board and it seems the same DIL package IC (with a heatsink) is connected to both outputs, which leads me to conclude that the IC is some kind of "power" op-amp.
The power specs of the hifi is 15W output...

I would like to know if I can make a conventional signal mixer with two 10K resistors - either for headphone or speaker out, as I only want to be able use the push-button/IR remote volume control of the hifi system - or will it present a problem with the outputs?

Thank you in advance for all the help

A passive mixer made with 10K resistors did the trick. Thank you.
