Users of the AES/EBU input and cables

[Mikeeo]

Hi,

I bring this message from the Devialet 400 & 800 forum as I thought it would be of interest to you who would like to connect your mono units or dig signal in to the AES/EBU input.

From my conversation with Thierry at Devialet:

"News flash!

Just had a talk to Thierry about the linking cable and the RCA--XLR connection between Master and Companion.

There is no setting for the AES/EBU input not even when configured for linking RCA--XLR. The AES/EBU input is strictly 110 ohm at all times.

So I asked Thierry how this could work then!

He says (which I didn't manage to read on the homepage) that when using the RCA--XLR link the linking cable should be 110 ohms and not 75!!! As the system will recognize the impedance of the cable. And this goes for all of us that would like to use the AES/EBU for a streaming input on the Master as well ie use a 110 ohm cable.
Connection is the 'semi-balanced' way as schematically showed on Devs homepage.

I told him about the Audioprana cables and the 75/110 ohm transformation. Thierry said it would not be a problem but less good as their own solution due to adding another transformer in the line of signal.

Strange that they do not mentioning this?

Well, I am ordering some 110 ohm diy cable. Any suggestions for a good one?

Cheers/Mike"

Already gave you a suggestion in the Master/slave link thread:

I use a Audience Au24 SE cable between my PS Audio PWT and master.

I could get Audience to make me a SPDIF RCA to XLR cable based on Devialet's schematic, but IMO, it's total waste of time and money.

You still have a 75 ohm output trying to drive a 110 ohm cable/input.

Mauidan,

Thanks, the link was noticed and I've ordered from them a few times.

According to Devialet the 75 ohm impedance is not the main driving force (or signal quality deciding factor) for the AES/EBU input but the 110 ohm cable. I can only go for that which I will.

I will let you know if it was a waste of T&M as I will def give it a go.

Best/Mike
