AES? Rackmount Synthesizers

I Haven't used it before so im a little confused
since AES is a Stereo i/o If i run a 8 Channel AD/DA into a AES i/o would all 8 inputs on the Converter be summed as a stereo Track? or would only Channels 1-2 Work?

AES/EBU is a digital i/o protocol. It has nothing to do with summing, nor is it stereo only. It is simply digital i/o. Where you may be getting confused is that AES can handle two channels over a single connection, however you can certainly break that out to two mono channels (though AES ports are generally stereo on multi-channel digital devices).

For example, if you have 8 channels of analog A/D and 8 channels of AES/EBU, the audio, once converted to digital via the A/D, can be routed out through the AES/EBU i/o. Vice versa for going the other way (i.e. AES to analog D/A).

Some examples of AES connections on outboard gear are things like an external CD player/burner. This would usually have stereo AES input and output ports on XLR. An example a mono AES device would be the TC Electronics Intonator which is a single channel pitch correction digital device.

If you don't want to introduce an extra stage of A/D and/or D/A and you have AES/EBU i/o on your interface, you can run AES out of the outboard gear to the AES in on your interface (and vice versa).

Hope that helps explain things!

Can a digi 002r take advantage of aes cables? I'm looking at a lynx aurora 8. I'm assuming that the db25 to xlr ins and outs connected to the digi via adat is my only option. However, I was wondering if the aes/digital connections can be utilized at all.

Unfortunately, no, the 002 (nor the 003) can take in AES/EBU. ADAT and S/PDIF are your only options.

Here for the gear

my understanding is that SPDIF i/p's can , in most cases be driven by a AES o/p's given a impedance converter / pad cable.
i found this super useful....

Interfacing AES3 & S/PDIF

I'm about to try one of these passive networks to connect an AES o/p to SDPIF i/p

Let you know what happens
