Hi,

I might be in the place to purchase a Lexicon DC1 V4 or DC2 V4. However the manual leaves a few questions or maybe I overlooked something.


Questions

========

1) can the volume of each speaker be calibrated in 1db or 0,5 db steps ?

2) can the delay of each speaker be setup in 0,5ms or 1ms steps ?

3) is the av-delay available in 0,5ms or 1ms steps ?

4) what about using just one rear speaker, but 2 sides ? I didn't see a compensation menu for selecting either one or two rears ? As we know there is a 3db difference with one or two speakers ? Or does Lexicon always want owners to use 2 rears or none ?


Thanks for any help on clarifying these issues.

Yup, that's their preference. Lexicon processors (and their proprietary processing) are designed for a 7.1 speaker set-up. If that is not possible, they suggest a 5.1 speaker set-up.


Best,

I used to own a DC-1 V4 but now I have an MC-12. I do remember that the av delay is not settable on a per speaker basis. It is just one number fot the whole system.

___

I also recommend the 7.1 setup, you wont be sorry as Logic 7 sounds fantastic properly set up.

Farscape,


please read again ! I asked for the delay for each speaker (how fine adjustable ?), but not for av-delay for each speaker !!! That's why I made up 4 separate questions !


AV-Delay (aka as lip-sync) is always just one value. This is clear by definition of the function !


Don't we have somebody with a DC-2 on hand for my questions 1 to 3 ?


Sanjay,

concerning 4) it's a pitty as I moved some furniture and might only have space for one back surround speaker. Just one back speaker would be something for a sort of "V5" software version I assume.....

DC-2 Ver 4:


1) 0.5 db

2) Rear delay offset 1ms steps

3) A/V Sync delay 1ms steps

Thanks for the help Kudret. But why only "rear delay offset" ? I thought one can set the delay for each speaker, first roughly for the closest and furthest away and then fine for all separately ???

.5db


"2) can the delay of each speaker be setup in 0,5ms or 1ms steps ? "


You mean for time alignment? As I recall it was like .3 feet per step.


There is also an additional offset for the rears available in some modes which was 1ms each I believe.


" what about using just one rear speaker"


No, due to the way we hear a single rear speaker is a bad idea. We can mishear it as coming from in front of the listener. Totally the opposite of what is desired. You either have a 7 speaker setup or a 5 speaker setup.


" Just one back speaker would be something for a sort of "V5" software version I assume....."


v4 is the last software upgrade for the DC-1,DC-2 and MC-1. All development now is on the MC-12 platform and sometime in the future a baby MC-12 based on the MC-12 platform will be released.

Hi Shawn,

Quote:
.3 feet per step
Oh, that would be very detailed. Excellent. Most often you have half a foot (ca. 15cm) steps or 0.3 meters ( = one foot). But 1/3 foot (= 10cm) would be really cool. I only wonder why then av-delay is not 0.5ms ? I can see the difference of 0.5ms steps on my screen. My memory left me, I could be happy with 1ms on the LEX, but I recall I used to have sometimes 0.5 and sometimes 1 ms for av-delay on my Meridian gear (depending on film).


Concerning the software version. I sometimes hear different remarks. The overall tone is obviously that no up-grades will follow anymore. But sometimes I hear rumors of an up-grade, about which we all don't want to speculate in here. Anyway. I just brought this up as most new decoders have a function to set for one or two rear back speakers. As the other speakers (mains, center, "rears in 5.1") are all dicrete as well I really don't mind one rear back speaker as I use direct speakers all around me. It might not be perfect, but at least one would have the option for a test.

Andreas,

I'm pretty sure that is correct, it may have been .6 feet though. The MC-12 is .5 feet and as I recall the MC-1 had smaller steps.


"The overall tone is obviously that no up-grades will follow anymore."


Lexicon has flat out said this on the Lex. forum.


"But sometimes I hear rumors of an up-grade"


Are you sure you aren't hearing about the possibility of a trade in toward the baby MC-12?


"I just brought this up as most new decoders have a function to set for one or two rear back speakers."


The MC-12 doesn't have it, Lexicon didn't add it in v1.1 so I doubt it will show up. They firmly believe a single rear center is a bad idea.

My questions have been answered and now we are going a bit off topic ;).


IMHO a baby MC-12 would have to have a serious price decrease, as the MC-12 is absolutely off the wall. I consider the MC-12 as well as the 861 as much too expensive. Actually I have the feeling that most processors are over-priced, but maybe it's just me or my wallet.


The rumors I heard was just a quick remark on the phone, so nothing we should take as serious. It just sounded logical, as the installed base of DCs and MCs (MC-1 that is) is quite big and shouldn't be forgotten. So a trade in for something like a smaller MC-12 would need to be price effective for the LEX fans already owning. IMHO Lexicon needs something in the price range of 3000 $ or they will loose customers bad.


As many know by now TAG is bringing out the AV30, a smaller brother to the AV32R. It lacks a few things, therefore the retail price in Europe is around 2700$. Considering it's flexible software (it's comparable to LEX and Meridian flexibility level) I would conclude "the race is on".


Without a doubt, the first major manufacturer with a software up-gradeable mashine in the 3K$ or below range will get a nice share of the cake. Rotel's 1066 is just the first wave....hopefully.....

Andreas,


Keep in mind that, even though it is not recommended, there is nothing physically stopping you from using a Y connector to combine the rear L&R outputs and run them to a single rear speaker. I mean, the Surround Police won't show up and bust you.;)

Is there any way you can fit two small speakers, even with just a minimum of spacing?

Sanjay

I don't think that's a good idea.

Well, that's why I said one could "try" out for a test. In reality it might not be a good thing as Buzz has thrown in. As we know now (well, I got it confirmed from the written above) Lexicon wants anyone to use 2 back speakers (or none), so they probably have adopted/optimized the logic steering/algorithms that way. Combining those two sort of steered "stereo speakers" into one speaker might become less than satisfying ? However, as said, if they would have included an option to choose one back speaker I would have assumed an adaption of the steering for it as well ! Conclusively that option isn't there. Therer are also other issues, but let's stop here.


Case closed.
