Ursa Major Stargate connections
O wise oracle known as gearslutz, I beseech you, hear my humble plea.

I have googled, I have searched the oracle and come close, but a certain surety of mind eludes me thus far. I am sure that it is due to my feeble mind, for which i deeply apologize.
-----

I went to go hook up my recently acquired stargate 323 and noticed that the xlr connections on the back had writing above stating:

INPUT AND OUTPUT ARE ACTIVE DIFFERENTIAL. REFER TO MANUAL FOR INTERFACING TECHNIQUES.

Refer to manual? You mean I don't just plug the xlr's in? I found the manual online, but being more musician than engineer, I can't be sure of what all the technical stuff was really saying.

Can someone please enlighten me? Is this something other than just a standard XLR connection? Or is "active differential" just another way of saying "balanced"?

Thank you in advance for any and all guidance on this.

I believe what they meant is that is their output circuitry was Active, meaning, no transformers. Op amps are used to provide the balanced signals instead of transformers, which at the time, was more "revolutionary" than it is today...
So I think you can actually plug that right into any balanced input. I believe the reason they wrote this in CAPITALS is because it is a warning that the output is NOT electrically isolated from anything you'll plug in, as oposed to a transformer which does "galvanically" isolate the output.

Go forth and connect unto the input device of your liking, provided it be of balanced nature, so say I, and no damage will beforth you or your heavenly chamber of sounds machine...

(or something along those lines)

yep, your inputs and outputs are eletronically balanced (the other way of balancing is done with transformers, see Balanced circuit - Wikipedia, the free encyclopedia if interested in detail)

just plug in those those cables and play! Remeber to check your control crystals and set the point of origin! :P (bad sci-fi joke... )

IIRC, the XLR pinouts are not standard on the Stargate. At least, they're not on mine! Probably best to check in the manual.

Yes, I've heard (this was before my time) line level XLR pins weren't always standardized.

The manual shows the pinout and there is a swap
