I wasn't sure of the connector on the GS-X, and you can have it re-terminated into 2 x 3-pin XLRs if you want the most straight-forward option. But I still like the convenience of the 4-pin XLR as the termination, and then use adapters as needed for whatever amp you have at the time. I have pretty much any kind of connector covered with various adapters, some going in each direction (M to F and F to M, etc). It is still too bad that Headroom went with the 2 x 3-pin as standard for their early balanced amps, when they could easily have chosen 4-pin and made all of our lives easier.
