WITHDRAWN

I have two speakon connectors on the back of my EA IAmps 500 one is labelled 1+ and the other is labelled 1-

I plug a speakon to speakon lead into the 1+ socket and connect to my Trace Elliot 1518c neo I then use a conventional jack to jack speaker lead to link the 1518c to anpother cab (4 x 10 or 2 x 10 )

so I never use the 1- socket

what is this all about what does it mean should I be connecting in a different way.

cheers

+1-1 relates to how the speakon plug should be wired for that cabinet

What it actually says is +1 / -1.

Both sockets are wired exactly the same and in parallel so you can use either or both of them (subject to not going below 2Ω).

You can ditch that jack<>jack lead and use a second speakon cable from the second socket if that's what you fancy doing.

Thanks for your help guys so I can use either or both sockets if I choose

I was intrigued as to exactly what the +1 / -1 labelling actually meant, so checked the manual for the iAmp 500 and it makes it abundantly clear:

"SPEAKER OUTPUTS: Two Speakon connectors, wired 1+, 1-."

The +1 / -1 label is simply indicating that the Speakon connectors are wired just as 1+ and 1-, so you can use any 2 way or 4 way connector. Some more cunning bi-amped setups might use +1 / -1 / +2 / -2 to send both signals down a 4-way Speakon cable.

Both connectors are wired in parallel so, like others said, you can use either/both of them, subject to the minimum total impedance supported by the amp.

And, BTW, in case you're still to buy Speakon cables, I'd always recommend getting cables with 4-way plugs on, rather than 2-way plugs, as the 4-way plugs are much easier to engage/disengage. It's still fine to have these wired with 2-core cable of course. I despise 2-way Speakon plugs!

You need to be a little bit careful with that.
A 2 way plug will fit into a 4 way socket, but Neutrik recommend [b]against[/b] using a 4 way plug in a 2 way socket because the latching mechanism doesn't work properly.
