Question about Audio Players & Recorders
The amp is a Roland JC-50 model 50 watt with a 12' SPEAKER, THE REVERB DOESN'T GET ANYTHING, I took it out of the cainet and
I checked the top of the reverb unit visuallyand everything seems to look okay,do I have to look under the reverb unit also to get a better look at the spring connections? also I noticed 2 additional fuses inside the cabinet beside the exterior one, could you tell me what are they used for.

SOURCE: Unit going into protection mode
You should first have or check the impedance and resistance of the speakers. then if all the speakers and wiring checks good, the only way to tell if this unit is good or the output section has no problems, is to hook up load resistors to where the speakers go, insert 400 to 1000 hz @.775MV into an input, hook up an osilliscope to the load resistors and slowly turn up the volume and see if the waveform clips before it shuts down. I doubt if you will have the equipment to preform these test but a good repair shop will be able to help you out. If it does not clip or go out then its all speaker wiring and/or the speakers.

You can at a minimum, bi-wire your speakers by wiring the speakers with the A and B speaker outputs. The A speaker outputs end up running the tweeters and the B will end up powering the woofers.

SOURCE: Zone 2 problem
I know this is old and im sure you have it solved by now, but it might be a good idea to check the amp setting of Zone 2. Is it switched to Internal or external? I remember something strange about this amp in that when you change from using the rear surrounds and go to use them in Zone 2, it resets the amp setting or something like that. Hope it helps if you still need it.
