Speakon bridge wiring

Just recently bought a Behringer NX3000 and it only has Speakon type connections which I've never used before.

Now I understand that the wiring is +1 and +2 but does it absolutely have to be a 4 pole connector to the A output?

I only have two pole connectors right now so I wired one to +1 and the other to +2 and connected them to both outputs, kind of similar to how you would bridge banana jack outputs.

So I just want to confirm that this is basically the same as using 1 4 pole connector. I assume it is, its working without issue.

In theory, that "should" work...

Yeah, should work. I'd still swap out for a 4-pole. This is basically why I only buy 4-pole Speakons. There's no meaningful price difference, and greater flexibility.

You don't need a 4 pole connector for the amp. That's only there for assistance in case you have 2 speakers on a single 4 pole speakon. The diagram on the back is sort of confusing. But the output A is a 4 pole and the output B is a 2 pole.

On output A, 1+ and 1- run Channel A.
On output A, 2+ and 2- run Channel B. <-- This setup is in case you have a 4 pole single speakon to run your 2 sets of speakers.
On output B, 1+ and 1- run Channel B. <-- This is the same as the above but for standard 2 pin speakons 1 per speaker set.

The way you've wired it is the only way you should wire it if you're bridging your amp into 1 channel. In this case, Channel A and Channel B are combined, and you use output A 1+ and 2+.

Standard 2 pole speakon connections for 2 channels on the amp would use 2 2-pole speakons where:
Speaker1 goes to output A, 1+ 1-.
Speaker2 goes to output B, 1+ 1-.

Hope that helps.
