Quick update. The ADX Maximus and cabling has arrived, all except for the 2x Neutrik NL2FX Speakon Cable Connector 2-pole. Can I just check with you @DM77 that you are suggesting I use the banana plugs for the ADX end, leaving the other end for the Speakon connectors in to the amp? I think that's right! I have wired up 2x banana plugs to one of the ADX for now, and will wait for the speakon to arrive before finishing the amp end of the cable. After that its just a case of learning how to configure the amp correctly. I decided to go for 1x ADX per channel for now, and will learn with that setup before deciding if I want to expand it.
