Sound Sets confusion

sometimes the loader recognizes the wrong voltage and say 5 volt when in fact it is a 3 volt sound file ! you have to try again UNTIL THE LOADER PROGRAM correctly  identified it as the 3 volt if in turn you are loading or downloading  the correct file you intended to download or up load to the engine!

The message I got said that the new 3v sound file was too big (2mb) to fit into the ps3 3v loco's memory (1mb). The loco is a premier ps2 - not a conversion.

The later 3 volt PS2 boards accommodate 2 Meg sound files. However, the older 3 volt PS2 boards will allow on 1 Meg files.

I've found that you get more reliable loading by powering the TIU and track with DC for loading.  I usually load them on the bench, a test track for assembled locomotives and the test set for bare boards or doing DCS upgrades.

John, I have not used AC to do a sound file in tears.  DC is the agreed hot set up.

What Barry Said.  Look at file size.  When loader is addressing board, look at what size memory the processor is.  Older boards are 1 meg.  Later boards where 2 meg as Barry stated.   Newer sound files greater than 1meg (1.1, 1.2 etc) can not load onto an older 1Meg board.  G

Thanks - I realize this now but my point is, the MTH Protosound website list them all as 3V, not by size.

Maybe I can go by catalog date. Do you know when the 2mb 3v boards replaced the 1mb boards in production?

by trial & error I figured out that the transition occurred right the 2008 catalog volume 1 or 2. Knowing this, I looked for the newest Premier sound set that is under 1 mb.  The Premier sound sets tend to sound a little better even at this primitive stage. I changed one of my steamers and love the results. I've downloaded some diesel sound sets and will utilize whichever one(s) sound best to my ear.

One of the nice things I've discovered with the newer sound sets is that besides better sound (more melodious horn, etc) the newer sound sets include the S01 soft key for a single horn/whistle blast.  Trying to accomplish a crossing signal sequence with the earlier sound sets was a challenge.

If you click on the sound file and save it to your computer in preparation for loading, your computer will display the file size.  Less than 1Meg is early, greater than 1Meg requires a 2Meg memory board.  G

@GG yeah, thanks but I'm well past that now. I'm practically a sound set Guru .

Having newer, sexier horns & whistles in so many of my older MTH locos now is a real treat. 

So many of my earlier PS2 diesels had exactly the same sound set regardless of what kind of locomotive they were supposed to be. I've given them all unique sounds.  

I also had a number of earlier PS2 diesels that all had the same "tugboat" horn even though the model clearly has a multi-note or "chime" horn mounted on top.  Fixed those too.

I've probably done close to a dozen locos so far and it feels almost like I had a dozen new ones.
