I need help, I'm planning to buy the Ampeg and the QSC. The QSC has only speakon outputs and the Ampeg has only jack outputs. Is it possible to make a cable with a jack plug and a speakon plug? Will this function properly? My cab has also speakon outputs so I could hook up the QSC easily. If I'm not able to take my cab with me,(lack of space in car) and the guy who's letting me play over his cab. has no speakon outputs, what then? I don't think if I make another cable with jack/speakon it could handle the power from amp to cab. The QSC has a TRS jack output where is this for?
