The send and return jacks are only meant to be used with external units such as reverb, effects etc. These units use a low signal voltage. You have probably dam,aged the internal circuitry. You will have to take the P.A. to a repair center that has experience with Fender products. Your warrantee if it is still in effect will not cover the repair. Soory to give you bad news.
