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.
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.
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).
