Post subject:  Lexicon LDD-1
So it came today but I've not tried since I think I have to switch the inputs for a coaxial SPDIF cable to the reciever so I ordered a convertor from Monoprice to use the old setup through a toslink optical cable that used for the Meridian 519 and which I won't have to redo my entire setup.

Will this work? Anyone try it this way and will I still be able to play the DTS like the Merdian 519 this way?

i have two of these. There are 3 inputs and 1 output on this unit. Inputs are 1 rf, 1 digital coax ,1 optical. Output is 1 digital coax. 1rf input has piority over rest and works only if there is ac3 signal. If no ac3 is detected, other digital inputs are used. There is a switch in the front to select between coax and optical. Regardless the output is always digial coax. It passes dolby digital, dts, 2ch pcm.

I'm confused...what is your question exactly?

using a convertor from digital coaxial to optical? Would it be the same as hooking it up by coaxial to the Pio reciever? the only out is the coaxial so I need a convertor to use my optical input that orginially was used for the Meridian which can output to toslink optical already so I suppose basically should this work the same as the Meridian setup but with a convertor to change from one type of cable to another one then on to the reciever. I hope that makes more sense.

so lexicon coaxial digital cable->convertor-> optical toslink Pio reciever.

I had mine hooked up that way at one point...don't remember it *not* working for DTS...

this works.
Using an ldd-1 myself. runs great. Nice to have additional inputs. ther's no difference in sound quality at all regardless of the rf demodulator brand.
own a few others, never heard any differences.

thank you. I now have to wait for the convertor from monoprice. I should have ordered that last week since it will be awhile before I get as Monoprice hasn't shipped it yet.

tried the convertor but it wouldn't work so I have it going through the Lite-on DVD recorder and when I need it for AC-3 change that coaxial to the Lexicon. At least this way I know it works.

It didn't work...? :thumbdown:

Maybe I misunderstood something here...
you wanted to make the coaxial output on the ldd-1 into an optical output by using a converter?

Post subject:  Re: Lexicon LDD-1
yes. Its fine this way though I just need to remove the cable from the dvd recorder to the Lexicon when I play AC-3 and DTS discs otherwise I just use the liteon dvd recorder. I wanted the optical so I could use the switch in the original setup but I changed everything. I wish I could have a more permanent solution than to always changing the one cable but I can live with this.

Hello xtempo. I know this post is long past your initial question but I just came across it now. I have used a convertor from Monoprice to change optical to a coaxial input when I had my old receiver with only a coaxial digital input. Same scenario as you but I went the opposite conversion. No problem passing any kind of digital signal. The only thing I didn't like was the extra plug used by the convertor. Had enough plugs in that power bar already.

i got Duncan to mod an optical TOSlink out so I can use that instead of the coaxial. At the moment he's working on it and probably will make the coaxial off and not output so it only outputs in toslink

now that I spent some time looking at other rf demods, this unit is interesting. it is the largest one by far. its nearly 18" wide. Although it has amazingly large estate, it still uses an external power supply. even the smallest Yamaha and nakamichi units have built in power supplies. Lexicon explains this as keeping interference out of the box from the power supply. It has control connections which are really relay switch and passthrough but they are proprietary DIN connectors. it is the only rf demod with digital coax out only. digital coax in theory is superior to optical anyway but it would be nice to have both. it is also well built all metal, you could probably murder someone with it.
