Surround Sound/Radio System

[alantina1997]

We have a 2013 Passport Ultra Lite 2020. For the surround sound, there are 3 buttons. A=front speakers, B=?, C=outside speakers. I'm assuming B should be the back speakers (by the bunks) however there are no speakers actually back there.

Also - Is there anyway when we are watching the DVD on the surround sound, can we also listen to the radio at the same time? I find it odd that we can't switch each speaker to it's own mode.

Thanks

The main amplifiers can only handle one input, so there is only one amplified output. So, one signal in, one amplified signal out. To listen to the radio while the amplifiers are producing TV sound would require two end stage amplifiers, something you're not going to find in a "standard model radio" found in travel trailers.

In our TT the three options are inside, outside & both. I don't know which buttons are which but that is the 3 options.

Yeah my A button is for front, B for back and C for outside.

With our radio system the speaker works as follows by controlling the switches:

Main Speaker Switch (A, B, or C) + Speaker Control Switch (Main off, Aux off, or All on) = Speakers with sound

- A + Main off = All outside speakers
- B + Main off = All outside speakers
- C + Main off = All outside speakers
- A + Aux off = Inside front speaker
- B + Aux off = All inside speakers
- C + Aux off = Inside back speaker
- A + All on = Inside front speaker & all outside speakers
- B + All on = All speakers (inside and out)
- C + All on = Inside back speaker + all outside speakers
