1. If each of the units have "Digital Audio" connections (except the TV) is it necessary to also interconnect each unit's "L/R Analog" connections?
In some cases, yes:
- Cable is sometimes a mix of analog and digital audio on different channels, so you'd want to hook up the analog audio as well and let the receiver automatically switch between the two when it detects digital audio vs analog audio.
- If you set up Zone 2 to play another set of stereo speakers in another room, you must have an analog audio connection if you want to send audio from that device to Zone 2.
2. Since I have only one "Digital Audio" input on the AV Receiver, but have a "Digital Audio" cable coming from both the DVR and DVD units, can I "Y" connect them or should I use an A-B switch?
You must use a switch but the receiver is already a switch.
The TX-SR600 is a few years old but I thought it had at least two digital audio inputs - one coax and one optical.
3. I understand that the AV Receiver's main function (aside from its tuner, processing and amplifying duties) is input selection and switching. In my case, getting the video to the TV is what I'm trying to do. Which video connection on the back of the receiver goes to the TV? The "Monitor" connection?
All of them, but according to a few little rules:
- The Monitor out has both composite video and s-video. You can connect both (to different inputs on the TV of course) but it will only output the same video format; in other words if you used a composite video connection from the dvd player to the receiver, it will be sent out the composite Monitor out. The receiver will NOT convert down from component video to either s-video or composite.
- The video out jack (composite) is always active but only if the source is composite video. If the source were component video, there would be no output at the video out jack. You would really only use that output if you were connecting a VCR for recording.
- The component video out will output component video and again only if the source is component video. If you use component video for one of the devices you'd connect the component video out to the TV. I don't remember if that receiver can transcode composite or s-video to component but if it can and TV supports component video, you'd use the component video output and not the Monitor out.
