I've cabled my house with ethernet everywhere.
For music I use from my sound card to the speaker several cable : male jack/RCA RCA/RJ45 cat6 cable (about 30 ft long) then RJ45/RCA RCA/Female Jack plugged with my speaker. It works.
I'd like to plug ITach on one end and the IR Emitter on the other end. Unfortunately,... it doesn't work !
Do you have any idea ?
Is stereo jack uncompatible ?
Is my overall cable length to long ? In this case, is there any solution Other than buy 7 ITach for my 7 AC splits ? ;-)
