Chalk up another new owner with a crappy sound system.
We are new owners not new to camping, just new Rockwood owners.
Went on our "maiden voyage" this past weekend to Mammoth Cave NP.
My concertone ZX500? has horrible hum in the surround sound.
It's not AC or alternator or inverter related because we were on
pure battery power and I shut off the TV and inverter.
As soon as a DVD tries to play and the menu with background music
starts there goes the loud hum in the surround sound speakers.
It's also in the 2 over the bed.
I tried shutting off the surround sound with just the 2 bed speakers
and still got the hum.
If I stop the disk the hum quits.
My quandry is I live 200 miles from the dealer!!
Is there hope?? Have some of you with hum been able to swap units
and finally find one that does not hum or at least has "acceptable" hum???
The unit seems to sound OK on all other modes, FM, CD, MP3 have no hum
although the speakers over the bed sound like crap. Our trailer was a
"show trailer" and we wonder if they cranked up the sound in a demo and
blew them out. Or they are just cheapie speakers.
Speakers I can deal with.
What do I do with this humming DVD player???
