I was looking at the ATI 1506 amp and was wondering how the trigger works for remote turn on. I have one source that says that I only need a 12 volt trigger supplying a minimum of 200 milli amps. However a different source says that it is done through a RJ 45 jack of DB25 connector using 50 amps (Optional remote power feature 50 amp relay 32 volt DC is applied to RJ45 jack or DB25 connector??) I thought that just two thin wires would be connected form the Lex to the amp and that was it! My lex does have a 12 volt trigger with a 500 milliamp trigger.
