Thanks! I hoped I just could drop in a new decoder without soldering. Can't I replace the Soundtraxx by another better one?

Which decoder could I buy to replace the built-in decoder?

You can turn down the master volume control via CV128.
P.S. The sound value Decoders are built by SoundTraxx in Colorado and are not "cheap"....

Then I need to POM the engine everytime I want to unmute it and mute it again. Unless there's a way to map this to a function key.

Additional question: where do I find a manual for the sound decoder? One with all of the CVs and the possible values.

Hi,

I have the Bachmann 2-8-4 Berkshire N scale with sound. I run DCC. Everytime I turn the power on the sound of the engine is switched on automatically. I then press F8 to switch it off. I only want to have it switched on when I run it. Unfortunatelly next time I turn the power on it makes noises again. How can I reverse this? All of the other trains are silent when the power is turned on and only get loud when I press the corresponding F key.

It's 20V (I can't change this. Anyhow this is the voltage that reaches the decoder not the motor. The motor voltage is controlled by the decoder and does not depend on the track voltage). I know that it's more than recommended but modern decoders can use voltages up to 22 or 24V. This is the only train that behaves like this. All other of my 50 locos (even American) don't have this problem and run normally. Also I can set the max speed to all of my 50 locos by programming cv 5 but this one here. I would consider to change the decoder but as it is built-in I can't.

Hi,

I'm new to this forum. I'm Stefan from Germany. Most of my trains are German but I also run some American. One of those is the Amtrak Acela #650 (Bachmann 83054) with built-in decoder. The problem is that it runs far too fast (~ 300 mph). When I run it it's already 100 mph fast with only step 9 of 128 steps (DCC)!

I can't change the maximum speed. The decoder doesn't react on programming cv 5 nor to the cv's 67 to 94.

Is there any way to make it slower?

Stefan
