Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems kind of 'digital distortion'

I am a very new member and I would like to know if any of the members have experienced repetingly but not daily loss of sound for one or two seconds and a distortion in the sound which I can best describe as a "digital distortion" or a very rasping sound. The problem has been reported to Meridian and they are working on it, but isn't solved yet(since november 2005).

G68D, G98DH, DSP 7000, DSP 5200 rear and center, Marantz VP-12S4 and Stewart screen.

Could you explain what type of source material this occurs on. For example, poor DTS lock is a typical source of "digital noise". Which Meridian equipment do you have and when does the noise occur?

Hi Paul,

I believe I have experienced what you describe via G98, G68 and DSP5000's listening to Red book CD's. Loss of sound is random for a second or two, but this rasping sound has only happened twice, but it is disconcerting.

Malcolm and MI',
Thank you for your quick responses! What equipment I own is in the message. The loss of sound and the distortion occurs very randomly on al my avaible sources: radio, CD and DVD. One day the set plays perfectly and the other day several times the loss of music and the distortion.
I don't know what is ment by Red Book CD's.
Regards.

Hi Paul,

Just standard CD's, I have not heard it with radio or DVD. Yes everything can be perfect one day then not the next. Playing a CD, it may occur once, play it again and perfect. Do Meridian know what is causing it, as opposed to having a solution?

Which software versions are you using, since I was told the latest software may be a cure. I have not upgraded since the kit is temporarily packed away,

What are you running for cables. Comms and Audio?

Improper cables can do some really strange stuff.

For the record I don't get anything like that on any sources.

Just DD drop outs on broadcast TV. Which is driving me insane because the TV's built in decoder seems to handle it (probably errors) fine.

If it occurs on radio then it is unlikely to be the G98 (sorry, I should have looked at the bottom of your message ref. your equipment).

If the noise occurs on ALL the speakers simultaneously then it is unlikely to be either the speakers or the leads. Looks more like a G68 problem. Update the firmware if you haven't yet done it as per the note above.

Hello George,

I am running all stock Meridian cables.

Regards

Nice pick up Malcolm !!

I do use comms and audio cables from stock and (because of the lenght of it) handmade by my dealer. For mains I use MIT Z-cords II and standard main leads didn't cure the problem. The most recent firmware is installed too. It's a real brainbraker I suppose.

Does it happen on ALL speakers like Malcolmw eluded too?

I also would start disconnecting Everything.

Narrow it to 2 speakers and 1 source and run for a couple days. Then if the problem is gone start adding stuff one at a time and run for a couple days. It could be one bad device rippling through the whole system. Like a bad ground loop in the digital domain might trigger a loss of digital lock. If it does still occur stripped down try a different set of speakers and a different source and try again. If every combo fails then that would confirm something is wrong with the G68.

George and Malcolm,
The problem occurs on all speakers indeed. I did forget to mention that in my earlier reply. I will follow George's idea and start with a small system. In my opinion it is a problem with the G68. I will report again.
