Thanks I was able to lower sound using my Digitrax 400 and changing CV 128. I do have the decoder Pro but there was no overall volume control. That is what came up on reading decoder was Soundtraxx dsd is there a specfic decoder the system should have read? Also if want rule17 what setting to use?
thanks again!

Thanks much great info will try tonight,,,

Thanks Hunt,, does this setting cover the horn and bell?

How would I lower the overall sound volume for this unit in DCC?
