This is a potentially dumb question. I have an Aguilar GS 212. It has two 1/4" plug inputs in the back, along with a Speakon connection socket. I am not using the Speakon connection yet, but i am planning to in the near future. My question is: Does it matter which of the two 1/4" plug inputs in the back of the GS 212 I plug my speaker cable into? The plug inputs do not have labels, such as "in" or "out."
