Bartok XLR inputs

[jarome (James Rome)]

Are the XLR inputs mono or stereo. For example, the XLR output of a miniDSP Studio has 2 XLR outputs labeled 1&2 and 3&4. Each of these is a stereo pair I am t old.

Bartók does not have XLR inputs at all, only XLR outputs R+L (and XLR4 headphone output in case of HDAC).

[jarome (James Rome)]

No, there are dual AES XLR inputs.

It looks as if both Bartok AES inputs must be used for stereo.

[Ermos (Erno)]

Ah, the 2 AES digital inputs. Yes, they also use XLR cables (AES3). But be careful to not mix analog XLR signals and digital AES/ XLR ones. Therefore it is best not to refer to AES inputs as “XLR inputs”.

The 2 AES inputs are used together for Dual AES sources, a single AES input for Single AES sources.

[FAQ] What is a Dual AES interface?

Dual AES is a digital audio interface invented by dCS in 1995 to allow high sample rate data to be split between two base-rate data streams for easy storage on the digital recorders of the time. For example, a stereo pair of 96kHz data could be split into two 48kHz streams and recorded as 4 tracks on a 48kS/s recorder. To replay, the 4 tracks are transmitted over two AES3 cables to the DAC, which reconstructs the original 96kS/s data. Dual AES was offered as an open standard and it was added to…

It has nothing to do with mono or stereo!

Actually Erno, AES/EBU is, by definition, digital stereo channels (albeit they can carry a monophonic signal by duplicating two subframe within the digital bit stream).

So, dual AES is in fact 2 x stereo (used to double the AES/EBU bandwidth as explained in the FAQ you quoted).

@Anupc indeed, I was referring to the above quote, that not both AES inputs are needed for stereo.

Ahh, I get what you mean! Yes, you’re quite right
