I have heard that it is best to rewire with the speakerlink cable to the first of every speaker pair, placing the AC12 behind the first slave speaker (as a backpack) before passing to the second with the existing meridian digital speaker cable. This maximizes the runs of balanced digital audio from processor to speaker and minimizes potential interference.

This would make sense and be nice but for some of us, rewiring is not going to happen.

Some details on the AC12 would be nice.
I thought it made sense to wire speakerlink up to the back of each speaker and convert there. If i now still have to run the old cables between the pair of DSP speakers it sort of bypasses the thought of the speakerlink advantage.
Also do i need to run 8 meter long RS-232 cable between the AC12 and the speakers ? Or for a software update i still have to hook up to the speaker itself ?

It seems silly to install 4 AC-12 units directly under the 861v6 and than continue running old cables (if you can rewire easily that is..)
Can we not simply buy a AC12 for each speaker ? (not very cost efficient, but ..)

I would like to see a couple of alternative small & simple boxes, one per speaker.

Master Version
SpeakerLink --> SPDIF, COMMS.
........... <-- MASTER COMMS

Slave Version
SpeakerLink --> SPDIF, COMMS

Nice & simple and installed either at DSP end or Process end to suit.

861V6 --SpeakerLink------------------> Box --SPDIF+comms--> DSP
OR
861V6 --SpeakerLink--> Box ------------------SPDIF+comms--> DSP

Regards
Carl

Did M not think this would be a good idea? I wonder why they went the 2 speakers AC12 route?

Master / Slave versions were exactly what I was hoping for as well. Not sure if this ever happen now M seems set to launch AC12.

My Dutch dealer informs me the upgrade price for the V3/V4 to V6 = 7500 Euro.

Much better than i expected.

The AC12 is a ‘dumb` unit so there will be no configuration from M config. As such it can only be used in pairs as ‘M` always have done with digital theatre, i.e a left and right pair or a centre / sub config.

Dimensions are to be as follows: 120 x 40 x 30mm smile

That means, the AC12 is either by the 861 and you can use the (installed) cables,
and I can use it theoretical for each DSP ONE AC12- if I want.

Does the AC12 have ONE RJ45 in, ONE SPDIF out, ONE com in and ONE com out?
Do you have a picture?
In which price area is the AC12?

Thanks

Robert

12x4x3cm? That doesn't sound like 1/2 rack-size to me confused

No existing cards from any age of 861 will work in the v6.

The AC12 retails for �400 inc VAT

New card costs:

ID40 Sooloos Card - �1,000
ID26 Digital Input Card - �550
OA08 Analogue Output Card (unbalanced) - �750
OA18 Analogue Output Card (balanced) - �750

Hmmm....I had hoped that trading in my 861 with two balanced output boards would have been retuned with a v6 with 2 balanced output boards....if not, thats another �1500 right there....so, �6500 upgrade, �1500 HD621, �1500 2*0A18......ouch

I just dont think its personally worth it. M's competitors have in terms of audio fidelity done a lot of catching up in the last 10 years and given the frustrations Ive felt with 'M' over the last few years (the prolonged delays with HDMI solutions etc), I just dont think I want to invest in them any longer.

My San Diego dealer/friend said most of price difference between US and UK is card related. I got the sense from his comments that M USA are trying to standardize products in the field. Not sure he's on board with that decision because he is VERY M competant. Maybe in US it's a good strategy to standardize, based on the dealer network. Seems like in Europe M have a different strategy.
