Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems SpeakerLink used as Digital Out (XLR or SPDIF) plus COMMS and RS232

Looking at the data sheet, it’s best to wire the transformer between AES+ and AES- to get the correct 110R load.

Here are some transformer examples below:

Hi VK,

Does the transformer pass 96kHz?

It must do as the MS200 is set to 2x

Figure 3 of Syles informative post

Should read

INPUT
AES3
110 Ohms (not W)

Discussed with Steve

Hector

Could I please check that I have the comms cabling correct to connect an MS200 to a DSP33? Could anyone confirm this is correct or put me right?



Many thanks for all help.

Hi,

Looks good, except that pins 1 and 5 should be linked in the DIN plug.

See SpeakerLink to SPDIF plus C5 (inc. Slave Comms Return) OR M5/S5 Comms diagram in first post.

Thanks Carl

I had looked at the diagram you refer to but couldn't square it with the comms pin outs in Duncan's info, which for the master speaker comms input does not have 1 and 5 bridged. As far as I could see only the slave input is bridged in this way. I expect I've got it round my neck again.

I just double checked using this Comms Wiring PDF from the Wiki.

I think you're right, though it probably does not matter if they're are linked; there was a tech note about having to do it when using an AC12 see AC12 M5 Load Modification.

I would like to connect AES/EBU to SpeakerLink.

I want to connect my computer to a DSP5200SE. First I connect the computer to M2Tech Hiface Evo using USB. The Evo has AES/EBU output as well as SPDIF using RCA.

I hope AES would be better than SPDIF. So I want to connect the Evo AES output directly to the SL input of the master speaker, using the wiring provided by this thread.

Is this a good idea that should work?

Yes it should work, you'll need to consider how you control the volume.

Good idea depends on what you mean? Playing music through Meridian DSPs always strikes me as a good idea!

Ha, yes always a good idea.

Thanks for reassurance with AES to SL. I read somewhere that the digital audio part of proprietary SL is not quite the same as AES because it has certain voltage differences. I was concerned that these may be important and might even be harmful to the speakers.
Please say if this could be a snag.

I thought I'd control volume at the speakers using the MSR remote.

My understanding (and I'm not doing this, it is simply my understanding) is that SL is not AES/EBU but the difference is more about the application of the standard than a significant difference and there's been several folks advocating wiring plans to convert SL to AES/EBU and I've not seen anyone come back and say it doesn't work. The DSP5200s do have clipping warning lights if you do end up feeding them too high a signal.

If you're concerned about it speak to Robert who makes and sells the reviver, that's certainly the cheapest off the shelf option and clearly works well (I have 3 of them). OR look out for an AC12. But those solutions do SPDIF to SL not AES/EBU.
