Lexicon owners please advise

I would make 2 suggestions.

One, is that you wait a bit. Most of the high end pre-pro manufacturers will be coming out with new pre-pros that will decode the new codecs.

Two, is to check out the following forum: http://www.smr-forums.com

Wish I could answer your other questions, but I'm just running an MC-1.

I have a MC 12B (have had for years). It has been rock solid-no problems at all and easily has the best interface of any processor. Logic 7 is second to none. That being said I am considering a the new denon processor becasue I am anxious to play with the new codecs that my Lex can not run (I do not have HDMI). So far I have resisted the urge. If Lexicon came out with a New version of the MC12 (or whatever name they choose to call it) I would buy it in a split second. Also the room correction is terrific- as are the analog outputs.

How much does lex charge for the HDMI upgrade?

"1) Have you had any reliability issues with the MC12? There seem to be literally thousands of posts dealing with glitches and upgrade problems for many of the processors out there, are the lexicons lest prone to this or are the owners just less vocal about it? If you have had issues how responsive has lexicon been?"

Lexicon's tend to have less problems. What problems do show up they take care of.

"2) Any issues on the video side that have required additional hardware, or any video performance complaints? "

There is no video processing in the MC-12HD. Whatever comes in is what goes out. The HDMI interfaces are for HDMI video switching and audio over HDMI. If you have to have built in video processing then the MC-12HD isn't for you. I use Lumagen Radiance with my Lexicon.

"3) How well does the EQ work and how much difference does it make?"

Works very well and I think most everyone has a positive opinion of it.

If your video processing delay is within the range of the Lexicon's AV Sync delay that it will work fine. I think it has a max of 60ms of delay. Plus the Lexicon has about 9ms of processing delay and whatever propagation delay there is from your speakers to your ears.

"So if I am reading this right I need to add an additional video processor if I want anything more than the DVD player outputs."

Or more then whatever video processing your display provides too.

"Does adding an additional video processor compound the A/V synch delay issue?"

It will have its own delay for its processing while at the same time adding it may reduce your displays processing delay since it will not have to deinterlace/scale the image it receives.

"please forgive my ignorance but if lexicon added an hdmi 1.3 upgrade with associated codecs would this be a software upgrade, an additional board that could be installed in the existing unit or would it require an entirely new unit?"

Wouldn't just be software since the HDMI board is v1.1 and the decoder DSP card doesn't have those codecs on board. Beyond that only Lexicon would know.

"Trying to sort this out further I called Lexicon support and they indicated that the new audio codecs are playable via the Lexicon as long as the player does the decode and sends this to the MC-12 via HDMI. Is this correct?"

Yes, the player decodes back to LPCM and passes that over HDMI to the Lexicon. The Lexicon then applies it processing (L7, bass management, room EQ..etc) and then converts to analog.

Keep in mind that the Lex will only decode 5.1 channels and use Logic 7 to create the 2 others. It will also not decode DSD through it's HDMI inputs....
