davidmbedardThe sound is best described as white noise...
That being said, I cannot recommend MRC sound decoders because of the problems others have had with them. I personally have exactly one MRC sound decoder(in an Athearn Challenger) and have not had any trouble with it whatsoever. I am satisfied with the sound, although it could be better. The motor control is not the greatest either, it's OK for how I use it - an ocassional excursion run through, but I would not want to use it for a lot of switching. There are a lot of people using MRC sound decoders that are quite happy with them, but unfortunately, there are also a lot of people who have had a lot of problems with them.
Do the engines require DC or AC current?
Jeff But it's a dry heat!
I'm talking about regular current, not DCC. I do not have a DCC system. Is there a sound system that could be put into a regular loco without DCC?
What type of quality control issues are we talking about here? The decoders burn out early?
And the sound does not need to be perfect or crystal clear, just something to give an added dimension to the layout.
??? I'd like to add on-board sound to my DC engines (i.e. constant diesel engine sounds), but is this possible without converting to DCC?
