Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Questions to 861v4 analogue output users and M support

As I bought a V6, I sold my v4.

The buyer need symetrical XLR outputs as he have no DSP.
Also I need some cards and he dont want all cards from my v4,
so finally exact these cards have to be installed in the v4:
VS50, IA00, OE13, OE13, EF20, CD20, IE42, IE16,IA45, CO00

As I want to do a good support for the buyer and get the optimal result,
I asked via my M distributor (M isnt talk to customer anymore as they have enough money I guess)
for the optimal placement of the cards.
After two months I got an answer of that difficult question:

"
There is a slight problem with the combination of cards proposed. If an
IA45 is used without OE12, the unit may not work. We discovered that
such a combination is prone to random audio problems.

So, without the IA45, looking at the back-panel, from left to right:

VS50, IA00, OE13, OE13, EF20, CD20, IE42, IE16, with the CO00 in the
extreme right-hand slot next to the power inlet.

With this combination of cards, you should have one of the short
terminator cards fitted on the right hand end of the motherboard - just
to the left of the CO00. There should be no terminator fitted to the
left end of the motherboard.

If you want to try the IA45, it would go to the right of the IE16 card.
However, you will then have to experiment with terminator cards at
either, both or neither end of the motherboard as we do not have
guidelines for this combination. Whatever seems to work without audio
"splats" or other strange noises is the right combination!
"

Its very interesting that

1)A IA45 "may not work" without a OE12
-its very deep knowledge from M about their own products-maybe the development is done somewhere else or just the service do not know anything about this?

2)Then the recommandations come without using the IA45 card,
interesting that M want to have a terminator on the far right side.
There was no info about that for customers at all

3)Install the IA45 card and just guessing where to place ONE or TWO terminators and have only a "seems to work" and "experiment with terminator cards"
give a deep inside where the quality of M is right know...


So my basic question here:

a)Does any v4 analogue uswer have the OE12 installed allready or not ?

b)Does any v4 analogue user have the IA45 without the OE12?

c)Does any v4 analogue user have "..random audio problems" or "splats" or "strange noises" ??


d)Does any v4 analogue user have heard about that before?


Please M technical support,
dont misunderstand me here.
Personally I find that writer have courage and is fair to tell all that truth and facts and gives a warning and recommandation.
This make me hopefull that M finally have the right people sitting on the places, but not the Managers or other incompetent people,
who are not telling or giving the suppurt the correct information or even get them the access to that infos.

We as the HH and the "hardcore fans" of M, have to protect people like this writer from repression of their chiefs.
Sorry to puplic that without asking(but who should I ask without a contact possibility?)
but I mean this discussion have to be started puplic to force M to think what they are doing here.

Maybe Bob when he is reading that and other posts, have still enough influences to stop that before his work is gone soon.

OE13 ?
Do you not mean OA13 ?

I had IA45 with OA12 and updated to OA13 withouth havind any problems.

And why have IE42 and IE16 fitted ? More inputs ?

IE42 and IE16 are both Master Encrypting Cards. IE42 replaced IE16 when 861V3 replaced 861V2. They are not meant to be used together. You can, but 861 gets confused when you are referring to inputs that exists on both cards. The results can be unpredictable. Trial and error is the approach.

Geir, where you have the source that IE42 and IE16 have not be installed?
You are guessing from the logical point,or refer to something?
Do you speak from experience?

Even M in the mail give no advice about these two cards as posted.

Robert

Sorry here,

I just write again the typo what M dit..
Of coarse OA13 for symetrical output.
IE42 and IE16 are needed, as the buyer have so many digital inputs.

Jaco, what M mentioned, is WITHOUT a OE12 "the unit may not work".
Do you have the OE12 installed or not?

Robert

Never had me a OE12 since i used all analogue when i used the v4.

Bought the OE12 when i went to DSP speakers, but since i stored them for a year now, the V6 upgrade was done before i could use it, so i sold it again.

The IA45 worked very well all the time, never strange audio issues.

Thanks jaco forthis info.
Where do you have placed the terminator?
Or maybe you have a configfile from that "old" setup?

Thanks

Robert

Regarding IE42 and IE16 installed in a 861V4.

I am speaking from experience. I had a V4 with both cards installed.

As I said you can, but are not meant to as only one IExx card is needed.
Any other Digital Input cards is IDxx.

It is possible, but my Config changed all sources connected to say
IE16.D1 to IE42.D1 and so on.

If it worked for you - good for you. I did not ever get it to work completely. If you need more digital input cards get an ID card if you can.

I used IA45 in a v4 without the OE12 card for years without any problems.

Robert,

I assume end of the bus somewhere, as when i placed the IA45 i did not have to put in or take out resistors.
When the V2 to V3 upgrade was done i had an spare set of resistors in the box. So perhaps than they took some out.

I not have these anymore, they went with the V4 to the dealer with the trade in i think.

Simon,

sorry about the late answer here.
Do you know where your terminator is located(physical not refer to the mconfig)?
And do you have one or two terminators?
Dit you have aOE12 before or wath that card never installed?

Tx

Robert
