Yes, it's all isolated from ground. You don't need an isolation
transformer unless what you are hooking up needs a ground.

Reading in the jupiter manual, it states the external speaker jack is not grounded
and the output is floating. I have seen suggestions that a audio isolation
transformer should be put on line between the radio and speaker. Suggesting if you
don't you can short out the audio amp in the jupiter. about as many also said they
just plugged in their 1/4" phone plug and every thing worked fine.
I looked at the drawing of J5, the the ext speaker jack I see no chassis
ground , is the jack isolated from ground? as long as the speaker in the
external,desk speaker
is also not grounded to the speaker case. why would you need a isolation
transformer?
Maybe Iam missing something
