I'm not quite sure what you are describing in your set-up. I assume you are telling us you are using a Lexicon, LDD-1 which is an AC3-RF Demodulator that accepts AC3-RF, Coax Digital, and Optical Digital inputs. You should be connecting your LD player's AC3-RF output and digital output (either optical or coaxial but not both) to this Lexicon and then from the Lexicon run a coaxial output to the AV Receiver. In addition, you should be running the LD player’s analog left and right outputs to a set of inputs on the AV Receiver. Look at this diagram on page 6 from the Lexicon manual..... https://manuals.lddb.com/AC3RF_Demodula ... 0,-154,393If your AV Receiver is built like many of the current designs (I know your Z7 can do this), you should be able to assign a digital input to an analog input of your choosing. And if this is done correctly, you can switch between digital and analog inputs on the AV Receiver by simply turning the Lexicon on (for digital) and off (for analog) assuming you leave your AV Receiver in "auto" mode for the audio input to sense an active signal (wait.... just realized the LDD-1 has no actual power button so you’ll have to put its power on a switched outlet to do this trick).

That way Auto-Detecting receivers would properly select soundtracks according to discs. So you think most LD owners in the 90s needed this in preparation for auto-detecting stuff that hadn’t been invented yet? There was no conceivable reason to shut the LED down so it never did. This was true of CD players so it became true of LD players. Personally, I’m not interested in any auto switching because it’s never going to be correct. Just switch it manually. How hard is it? Are you out of digital ins or something? There are three different soundtracks on an LD (potentially) so at some point you’re going want any one of them, so you the viewer are the only one that can tell your gear what you want.

Thanks guys. I think you answered all my questions. Unfortunately as you guessed I do not have enough free inputs on the receiver to use more than one for my LD, but that was a good suggestion.
Yes, I'm running AC3RF & SPDIF into the decoder so optical input is unplugged. Then analogs run straight from LD to same input on the receiver as demodulator's COAX out. This basically gives me the same functionality as if I installed a power switch as suggested. Since the demodulator disconnects the COAX signal when flipping the front panel switch to "Optical", no signal is present on the receiver's COAX in. The auto mode then correctly selects the analog inputs. Not a bad setup. Well, anyway that gets me off of the couch an extra time now & then when I forget to change it while going from one disc type to another. I just have to be careful because I can end up with the AC-3 going into the analog on the receiver. (wakes me up! no damage so far.) I already re-labeled "Optical" to say "Analog" to help me remember.
If I were to do this with the Yamaha remote it would be: Menu move up or down to: Input OK move up or down to: LD Sub menu move up or down to: Audio OK ...and finally move up or down between Auto, HDMI, COAX/Optical, or Analog OK Menu (to exit)
I'll save that for when I'm sick, broken leg, old, or all 3! lol.
Thanks again!

However, thinking about his some more, a better solution than the one I mentioned before would be to assign the LD player two inputs on the AV Receiver. It could be something like this...
BD/HD DVD (all digital) >> Run composite video 1 from LD player to AV Receiver on BD/HD DVD input. Then run AC3-RF out and a digital out (either optical or coaxial) to the Lexicon and then from that a Coaxial Digital Out to the Z7 on a Coaxial Digital Input assigned to BD/HD DVD input.
DVD (all analog) >> Run composite video 2 from LD Player to AV Receiver on DVD input. Then run analog left and right also to DVD input on Yamaha.
After this is done, you can play back all three formats with just switching the appropriate inputs on the Yamaha and Lexicon. This is provided you've got the extra inputs. I've got an HLD-X9 using 2 (Muse and NTSC PCM+AC3) and 1 each for DVL-919 (Analog/PCM/DTS/AC3), LD-W1, VP-1000, DirecTV, XBox, Wii, VHD and the front panel inputs for whatever player I happen to be fixing this week.

I've had to make do w/ taking advantage of my Denon's input assignment feature and literally double up some of the inputs (e.g.: my "HDP" input has a Blu-Ray player on HDMI and a DVD Audio player on Component Video - S/PDIF - 6 ch Ext) to free up resources In any case, my LD player works perfectly w/ my current set-up to provide all three audio options w/ ease of switching (AC3-RF and optical to my Sony, SDP-EP9ES and analog L/R directly to the Denon). Later on, I will be dropping my CLD-3030 and swap in my CLD-D704 and CLD-D703 w/ built in AC3 Demodulator to finally get my "2nd" dual player auto reverse set-up completed. Isn't it great too have too much equipment.
