I think this is just a kind reminder to all of us who have had this demodulator in the set up.

As the 519 does jitter reduction over the digital input then my yamaha htr 5940 does not accept the processed digital output thus no decoding is performed at all. I love this device quite much if a decent AVR is in use in future.

Topic review - Meridian 519 digital input and output

I have 2 x 519's and one of them is connected to my HLD X9, which is connected to my Lexicon MC12B (2008 upgraded version) and it works perfectly well in my setup.

I love the build quality of this unit.

Regards to you

It's a good, solid piece of hardware. Another plus for us Brits is that it was made in the UK so we don't have to muck about with power converters like we do for just about every other demodulator, though I'm not sure if that goes for Australia too or not.

I've not had any problems with receivers not accepting the digital signal. Does this only happen for you when decoding ac3 through the rf input? Can you pass through a signal fine from the digital inputs?

Thanks guys for all your input. I have 4 of this unit Two of them are 240V and the rest is on 120V.

When RF is fed into this unit the output AC-3 stream is treated well by the receiver. But yamaha 5940 is a generic model which does not accept any sort of processed digital input from what I can see at this stage. When I tried my B&K DT-1, which does not do any jitter reduction, the 5940 works like a happy boy with the digital input.

For sure, 519 is a good quality demodulator and that is the reason why I came across 4 of them. If I could grab a lexicon something I would never worry about the issue I found on 5940. Money talks this time

Good day tomrlee_m998,

You are welcome sir,

I have the Lex LDD1 RF demod as well but haven't got round to connecting this yet.

Most of us members have gone through many challenges to get all we have and so feel confident knowing that you are understood amongst the many of us here.

Regards to you

That Lexicon is the first AC-3 demodulator, designed and made by MSB, first as a prototype for Dolby and then into an actual product for Lexicon. I think it's the only one to have the ability to compensate for the different AC-3 RF levels various players output.

Which is better , meridian 519 or the lexicon ldd-1? I just recently got into laserdiscs and I'm trying to figure out the best arrangement ?

Good day herb_vogel,

1) Lexicon LDD1 RF Demodulator
2) Meridian 519 RF Demodulator

I would say are the best built however, all Demodulator's essentially have the same chips inside, so any other internal refinements or adjustability i.e. The Lex offers the little more flexability for different players.

I shall be checking this at some stage when I connect mine.

Kind Regards to you.

Lexicon is 17" wide component size.

They all the same job, convert the ac3 rf signal to digital....you are not going to hear any difference between models as it is a digital conversion.

I have pioneer rfd-1 and it's perfect, I can capture ac3 and dts bit perfect on my pc using a audiophile 2496 pci card.

The only difference between models is the ability of some to connect more than one input., ie dts on toslink and ac3 via coax and autoswitch between them so you only use 1 input on your avr.

I capture the streams via coax and the toslink sends the stream to my avr at the same time...I see no loss of data... the captured file when sent via spdif from pc to avr is recognised as dts/DD and plays perfectly indicating DTS or DD on the avr display.

I have no experience of the meridian but it maybe an avr issue.

I bought one a few years ago and then the sound stopped so I got a Lexicon. I wish the Lexicon had an on off switch otherwise it seems it is the same quality. I also recently bought a Pioneer SP-99D but I think I need to get a remote to actually use it. Harmony doesn't have all the remote functions in the database so sometime I need to order the remote from Pioneer.

i had the gold Japanese version of the SP-99D and i was able to use all setting without a remote.
from what i remember it was the same model just gold rather than black.
and Japanese.

I can't seem to get sound out. I have the CLD-79 by rf and optical to the SP-99D and from that to my VSX1019AHK multichannel in but so far I am not getting any sound. Do you have any ideas?

1-make sure your receiver is set to "6ch external input"
2-plug in some other source(LD analog out) into 1019's 6ch external input directly. You don't need 6 rca, just try 1 or 2 rca's for testing.
if you get sound here then you know your receiver is fine and the problem is your 99D.

1- try connecting LD analog out to 6ch input on 99D. Again 1 or 2 rca is fine for testing. See if it passes sound to your AVR.
2-try optical or coax from LD player into 99D then see if you get anything. (this is assuming your LD players works %100)
if you get sound here then you know you narrowed it down RF input on your 99D.

Let me know which step you get stuck, we will go from there.

I have the analogue line in and no sound. Could the settings be all the way to the left. I can change center and rear but not front.

Also when I push the test tone no sound comes out. The seller was an idiot and did not pack it well but it didn't look like it was damage which was lucky.

did you test your receiver like I explained above? try another source on the 6ch input, make sure it works first.

you can also plug left and right output from 6ch out on the 99D to one of the stereo rca inputs(cd, dvd etc..) on the 1019. Do you get any sound this way?

yeah, like substance said.
it's been about 10 years since i had mine so i can't help too much, one of the reasons i almost had ulceres and sold it :LOL:

i had the VSX-55TXi, i remember there was a 6 channel input but then you had to select the bypass on the front of the AV amp i had for it to work.
and i only used the AC-3 straight to the gold AC-3 demodulator and the optical straight from the LD to the AV amp, not into the AC-3 at all.

I have had my DV58AV (DVD-audio and SACD) hooked up in mutlichannel and it work. I should have mentioned it earlier.

I will try the rf and the optical.

I have tried all inputs from the LD player and nothing has worked. I will try from another source to see if that works. I do know the CLD-79's rf and optical work because I had the Lexicon set up and I have had the optical straight to the VSX1019AHK also.

It looks like its working but again there isn't any sound. Are you sure I can use this without a remote?

I just got a Meridian 519. AC-3 RF demodulation works great, but I can't get PCM pass through to work. I tried with Yamaha DSP-AX2, Yamaha CX-A5000 and Denon AVR-3200. Does the Meridian somehow change the PCM signal so it's no longer standard? Is there any tricks that I can do to make it work with Yamaha? Perhaps some digital-digital-conversion box?
