Hey,
i just sold my lexicon dc-2 to tk2001 but he has noticed a problem, something i didn't notice at all when i had it, but i think in all fairness i should try my best to sort it out.
He has noticed that everything is fine with movies but for some reason with stereo the sound is mainly coming from the right speaker and vocals are not centred.
am i right in thinking that l/r balance and calibrate panorama would be able to sort out this problem?i didn't really listen in stereo, but when i did i never noticed this. Or is this a problem that needs to be sent to a specialist repair shop and fixed?(hope bloody well not)
cheers

What CD player is he using?

It sounds like a rather simple problem. Either the volume on the processor isn't balanced (I know I know!). Or his CD player has variable volume outputs on the phono outs & isn't set evently either.

Failing this, you're buggered.

He's compared it side by side with his MC-1 and there's no problem there, so unless it's a panorama issue (which I doubt as he probably reset the processor to factory settings before doing his own setup) then it's something else.

Dimmy,

The DC-2 is set-up exactly the same why as all my previous processors - each speaker/sub is calibrated to 85dB using Avia and an SPL meter.

I don't have a CD-player but I do use my Toshiba SD900E to play music cds. The SD900E is connected to the DC-2 by digital-coaxial, optical and a pair of analog cables and the problem occurs with all three connections.

I have used a entirely different source to play music cds through the DC-2 and the problem is still there so that rules out a possibility of there being an incompatibility problem with the DC-2.

The fact that I also have an MC-1 to test against comfirms that a problem does exists with the DC-2.

But a problem you didn't notice at Fred's?

i agree. tk2001 you should have been 100 percent satisfied before parting with your cash, you of all people knowing this kit to be 4 years old and your previous worries with its condition/previous owners. you were happy with it when you bought it and happy when you got back. I did not notice any problems at all with it and treated it perfectly since i got it. i offered to give a longer demo but you were perfectly happy with what you saw and heard so you left.
as far as i am concerned anything that happens after that is of your concern, how can i know that you got home and dropped it?as you can see on my feedback you also left good feedback showing that you were satisfied when you got back.

Have you done a complete factory reset and started setting it up from scratch?

The fact that the digital and analogue inputs show the same symptom mean the A->D converters aren't at fault.

Have you tried other inputs? Do they do the same? Balance is set to middle? (I doubt the calibration levels will be affected by the balance)

Zone 2 balance? Calibrate Panorama setting?

If the other inputs don't have a problem have a look at the CD input settings, what PCM, AC-3 and DTS FX is it set to?

And then there's the customisation of all the effects, which include L-R balances and loads of other wierd settings.

Have you done the internal self diagnostic test?

Fred, that wasn't what Dimmy said, you just extrapolated a whole lot. Don't panic just yet (that's what your posts sounds like, I'm just commenting not criticising). Try to help tk2001 and see where it goes.

Dimmy,

Firstly I was in a rush to get home due to other priorities so I could not test the unit out thoroughly and I made it clear to Fred that I could not stay long.

I just needed to make sure that it worked and that would have reasured me that when I got home there would be no problems with it.

I calibrated and set-up the DC-2, out on a dvd and everything was fine.

Then I stuck on a music at low volume levels (I like to listen to music quiet at night) and noticed an immediate problem with the DC-2.

fraggle,

I did all that and then some.

I have exhausted all the possibilities.

Hmm, toughie.

Have either of you consulted admin on this?

I'm not to keen on your attitude Fred and now you are accusing me of dropping the unit and this is taking into consideration that the DC-2 did not come with a box and that I had to CAREFULLY pack the DC-2 up using MY Lexicon MC-1 box?:nono:

Every single equipment/item I have sold on the forums has been in great condition and 100% functional otherwise I would include and describe the fault in detail on the thread.

If there was anyone in the forum who has brought something from me and has had a problem with the product that I've sold them (none so far), then I would do everything in my powers to resolve the problem. The last thing I would do is accuse them of dropping the product.

Yes, perhaps I should have tested the unit out with music cd's before giving you a possitive feedback.

This is obviously an issue you're not going to resolve between you.

Whilst I agree with Fred - the unit was working fine whilst in his posession (if we're to take his word on that) - it's also entirely possible that it wasn't.

Whether the responsibility lies with Fred for not realising this himself before advertising the processor for sale or whether it lies with TK2001 for not demoing it properly is something I think you should both consult Spectre on.

If you like I'll PM him with the URL to this thread.

Perhaps it would be a good idea to get this checked out by a Lexicon dealer before taking matters any further.

Chips - AFAIK (or, as far as Fred's told me off the forums), TK2001 has already asked for a refund.

tk2001-i wasn't accusing you of anything i was just saying it was a possibility-i don't know you and it is amazing what some people claim with second hand equipment.
But as my feedback shows everyone i have sold stuff to were all very happy with the equipment and that it had no faults as i do look after my equipment very well.
This is a sticky situation for both of us. I do hope the problem can be rectified and that it is something simple, as chips says going to a lexicon dealer and finding out what it is.

Dimmy, thats not entirely correct what I said.

I told Fred that unless this problem could be resolved, then have not other option but to ask for a refund.

Fred, as you is doing everything he can to resolve the matter.

But surely I shouldn't have to go through this process?

If the fault was caused by me then yes, but it wasn't.

The problem is that until the unit has been checked out, we don't know what the problem is. Is there a lexicon dealer close to you who could take a look at it?

but how can you prove that it was faulty at my house?i listened to it a lot, especially in stereo with music, as i had no pj for the last month, and noticed nothing you described.
You should have been the one who should have got here earlier and allowed more time to examine a 4 year unit that you already said you had your doubts about and which i offered, i would have spent an hour with you at my house making sure it sounded as expected. You did make comments about what state the components would be in so, as i blatently offered, a longer demo and examination of the kit.
fred
p.s by me starting this thread i have made an effort to help resolve the problem, i haven't just told you to f off which some sellers might do.

Fred, you have stated that you listen to your music in stereo but at what volume do you listen to music at?

When I was at your house, yes we briefly listen to music but the DC-2 was deffinitely not set to 2-channel mode, it was set to music logic.

As I have descibed in detail, the problem is only apparant when you listen to 2-channel music at low volume levels (under -55dB) which is how I like to listen to my music at night time so it directly affects me. You might not have been aware of the problem in the first place but nether-the-less the problem still exists.

The question is should I have to live with it due to no fault of my own?

While I do appreciate you making an effort in posting this thread, I do not appreciate being accused with the possibility of dropping the unit.

I don't think that who said what to who is appropriate for this forum as is the intervention of third parties so could we please confine this thread to technical arguments and possible solutions only.

Could it not be a prob with you Tosh player then........maybe it is not putting enough voltage into the lexicon at this volume, to get the channel active.........???
Have you tried it with another player........???
