Yes-You sure got a good buy on your total
system.
Yes-Im sure your unit has a large multiwire
connecting cable running from the mixer to the PA. No you can't see it-it is located in the frame of the box that surroundes the mixer & PA amp. If you took out the screws
that holds the mixer into its box,and lifted the mixer panel out of the box, you would see how the cable runs from the mixer to the PA. You can go to the search engine 'Google'
and type in 'Fender, Model #' of your unit-
I saw a business listed that can supply an operating manual/schematics-I'm sure this would help you understand how to operate your
system. Does your mixer have pan pots?. I believe I've used a similar system. With your pan pots set to midway (12 oclock) you will send a equal signal from the channel in use to both amps. If you had stereo outs from a keyboard, you would 'pan' one output to the right, the other to the left for a stereo effect. You can also pan your used channels to one amp-and use the other amp for a monitor amp. I'm sure if you had the operating manual for your unit or someone experienced on this board to show you the 'in's and out's' of it-it would all come 'clear' to you in short order!
