I have a Panasonic AE-2000U projector mounted to ceiling. I want it to take only one HDMI video feed, and have the speakers (on wall) to take the audio feeds from either a cable box or a receiver. I also want to play CD/DVD/VCD some time. Is it a must to have such a receiver? Can I just leverage the cable box?
I was told the speakers (on wall) are A/B type (what is it?) What kind of receiver is able to handle the A/B type?
Many thanks.
