So I wasn't sure if this posting should have been in the "LD Player" section or this "AC3RF Demodulators" section as the topic I'm writing about is a bit of a hybrid. In the end, I decided it really was more about Demodulators so here we go.
What I have in the following pics is one of my home theaters that utilizes dual players that are both capable of outputting Dolby Digital, DTS, PCM and analog audio. I recently made a change to this set-up by adding a Denon, AVD-2000 to act as a switch box for the two players and then having the signal carry over to a Denon, AVR-3805 (via S/PDIF optical).
So here are the two players. One player has an AC3-RF out mod and the other has the same mod but with an internal AC3-RF Demodulator.
Next up is the back panel of both players showing two sets of digital outputs from each player so I can send Dolby Digital (on the modded outputs) and PCM/DTS (on the factory S/PDIF outputs).
Now we see the back panel of the Denon, AVD-2000 showing what connections I have coming into it from the LD players (Player 1 connected to "AC3-RF" and “Optical 1" while Player 2 is connected to "Coaxial 2" and “Optical 2"). Also, I do have the S/PDIF out of the AVD-2000 actually going to a S/PDIF splitter (the square box in the pic) to create a dual S/PDIF out so I can run two sets of digital outputs to the AV Receiver to sync it with the two players video and analog audio outputs.
Finally, a front image showing the basic signal flow of all the "digital" connections (the LD players video and analog audio connections are going directly to the AV Receiver).
So the beauty of this system is that I literally have two AC3-RF Demodulators to pull off this dual player set-up (one demodulator in player 2 and another in the AVD-2000 processor). Also, since I am using the AVD-2000 as more of a switcher, it solves the issue of assigning multiple digital inputs on the Denon AV Receiver since as we know it's a pain that we can't assign more than one digital input for every video/analog audio input.
Now I just sit back, pop in two discs at a time like a Pioneer LD-W1 (keeping one player off at a time), and enjoy a movie in any sound format I want with the utmost ease in switching inputs.
