I’m considering buying a new receiver here soon and I’m just a little confused on the HDMI part of it. I have tried searching the web to see how it works but not much luck. Is the receiver basically grabbing the audio signal and letting the video/audio signal go through to your TV? And I’m guessing this depends on each model but if I have 4 HDMI in ports do I have 4 HDMI outs? I know its a silly question just wanting to make sure I am grasping it correctly, and what better place to ask it?
