AES/EBU = Emotiva XLR cables??

[roman]

I have a Sony CDP-D500 that I'd like to use AES/EBU cables for the output. Can I use the Emotiva XLR cables or should I find cables that are more specific in the product description for this??

I don't believe they are one and the same. I believe Emo have an AES/EBU cable in the pipeline.

all it is is a XLR cable....that is exctly what i use is an Emotiva XLR cable on the AES/EBU port.....talk about some signal!

STRAIGHT OFF THE PRODUCT PAGE FOR THE ERC-2

"If you wish to use the ERC-2 as a high quality digital CD transport, rest assured, we've made it even better in this regard. New to the ERC-2 is a professional grade AES/EBU digital output connector via XLR."

if that's the case then it's a no-brainer!!!! I have read that AES/EBU cables have a specific 110 ohm load on them and regular XLR cables don't.

you have a Private Message.

Here's a silly question. 3 conductor XLR cables carry balanced analog audio.

Is AES/EBU digital "balanced" as well? IE, a 1 paired with every 0 and the signals combined at the other end?

If not, does the same signal go through both conductors, or is one of them unused?

[House]

now your beyond me :-)

An inverted signal, non inverted signal and a return signal make up the three pins.

thanks to all for helping with this question that really doesn't seem to fit the "newbie stuff" area now. LOL!!! Unless Emotiva or someone here can verify the 110 ohm spec on the Emotiva XLR cable, I'll just go with this:

The Emo XLR is close to 0 ohms. Like .03 or something.

I should say that no cable can be 0 ohms.

Just go with the proaudiola cable; it's got what you need. done & done!

Get the digital 110 OHM AES/EBU cable from Pro Audio LA.

You should use the specific 110 OHM cable and Pro Audio LA makes very good cables with high quality Mogami wire and Neutrik XLR connectors, these are among the best you can buy.

The AES/EBU cable has a 110ohm impedance. I'm not sure the analog XLR cables have the same impedance. Although there may be some success in using an anolog cable for digital duties it is not the intended use.

I would buy the correct cable and I'm sure Emo have said they are working on it.

Thanks again to all for the input - hopefully others have learned about this connection type for future use. Ironically I'll be posting the CDJ-D500 on Ebay tomorrow as I have decided to go with the Logitech Squeezebox (will be using the hacked USB output firmware with it).

Thanks again guys!! You are very helpful and knowledgeable!

I know that's the case for balanced analog preamp signals over XLR.
Are you saying that's also the case for digital AES/EBU?

[wizardofoz]

As far as I know all the XLR cables I have seen use 110ohm balanced cable...that's the standard IIRC

[shayned]

Yes, digital cables are differential(+ve,-ve,ground).
Digital ones need to be 110ohm, but so do the connectors, ideally.
Analog ones do not. The AES/EBU is a connection type, usually referred to as XLR.

Balanced connections work by common mode rejection-look at it like this:

If you were to graph a sine wave(pure tone, for simplicity) everything above the x-axis is the +ve signal, everything below is the negative. Any noise that shouldn't be in the signal will be present on both the positive and negative, and is therefore rejected, meaning a cleaner, quieter signal. This is much more important for extremely long cable runs(ie pro audio, studios, etc) as longer wires make for better antennas, picking up crap.

Hope this helps.

either way i still ordered a 110 ohm rated XLR cable to replace the Emo one i am using now....as Emo doesnt have a 110ohm specific cable.

OK, beyond "Newbie"but in regard to a previous post that said

"The Emo XLR is close to 0 ohms. Like .03 or something.

I should say that no cable can be 0 ohms."

That is the Direct Current Resistance. An Alternating Current sees an impedance which is formed from the inductance and capicitance properties of the cable as well as the D C Resistance. Now you know why this isn't "newbie".

But the "newbie" point is, D C cable resistance is not the same as impedance. I don't think the impedance mismatch is an issue here for these balanced cables. Your source output impedance is unlikely to be the same as your input impedance on most of your RCA input devices for example. Impedance mismatch tends to matter more for very low signals, such as MM versus MC on phono inputs, and large power, such as 4 or 8 ohms speakers
