DCC Sound Locomotives

[mjlloyd]

We have recently purchased a Spectrum DCC locomotive but the sound is to loud - is there any way to adjust the volume?

[mjlloyd]

yes, but how do we access the decoder to reset the value on cv 128. we are using the engine with a regular dc controller

[mjlloyd]

I am such a novice, like who would be able to do that?

Thank you very much for your help.
