Okay, I purchased one, finally got to trying to hook it up tonight. True, I'm "old school", but where do you put your 1/4" phono jacks ?... According to the manual :" The SHUTTLE 6.0® provides two Neutrik Speak-On connectors (wired 1+/1-). The speaker jacks are paralleled."... my 1/4" jack are WAY too tight to be inserted fully into these things... should I go for broke & force them in ?... or are my regular chords too "outdated" for this amp ? I could get them in to an extent, but I'm not out to destroy a brand new amp ! True, dumb question, but still.
