| Sends/returns on amps are unbalanced. Manuals should tell you. Looks like all should be reg quality guitar type instr cables. One way to tell if a jack is TRS/balanced is pop a reg guitar cable in the jack. If it's balanced it will click/ stop before it's all the way in. And click a second time when in all the way.
If it goes all the way in with one click it's unbalanced.
