Can I conect harman Kardon avr 230 to apple tv

headphone is audio out for your headphones not audio in. you will need to buy mic pre amp and use output to aux or preferably tape in RCA connectors.

audio out from tv to audio in on the avr

optical / digital connection is the best you are going to get

you must contact to the supplier manufacter via ONLINE chat and get support or call to the toll free for the consultation.

God bless you

The 'needs' of the HK??? Like for setting it up and managing it?

All an AVR needs is a basic composite video output at its end and an input at the TV. They ALL have that.

Yes. One, for whatever you want to feed it.

connect tv video in to kardon video out (tv audio in to kardon audio out) dvd audio and video out to kardio audio video in. and if you what to record also signal from tv. make a cable from tv audio / video out to kardon audio / video in.

How is TV audio (from the cable box) getting into the Receiver? If digitally, you wouldn't be missing any one channel on a connection malfunction, you'd lose them all. If analog, swap the channels around to isolate the problem (and reconsider using digital).

You are overdriving the amp, they were never meant to be played at that volume despite the fact they will go to that level. Your only hope is to buy more efficient speakers or a stronger amp.
