Thanks,   I will try that next.

I will try that, but what about drilling out speaker housing holes will that help or hinder?

Hello,  I have the Bachmann DD40AX with the sound value decoder, my issue is the volume of the prime mover's, bell and horn can not be adjusted even the master volume I have set the corresponding CVs above the default settings to no avail. other sound value engines are much louder in all aspects. I checked speaker wires and all seem to be connected. what is the next course of action. thanks

Hello to all

I tried the cv settings as suggested and it seems to be the same , the horn volume to low, I will check the speaker wiring next.

thanks

Hello
I have a Bachmann DD40AX sound value Engine, The issue I have is the sound of the horn and prime movers is very low compared to the bell sound, even after changing the CVs I can't seem to increase the horn or prime mover volume, but I can increase or decrease the bell volume I have tried the master volume CV and the volume does not increase. what if any thing am i missing?

Thanks

Wondering if Bachmann would consider producing a GP15-1 (Frisco version) In the Wisconsin Northern version Road # 1501 and 1502, These are used in the sand industry.

Thanks to every one.

Was this on the Bachmann site or the Tsunami site? and how did you find this?


Thanks

I do understand that the Decoder does not have all the functions as full function decoder does, But then why do they not publish instructions on which cvs can be changed so you don't have do trial and error on all the cvs that are listed with a full function Decoder to see which ones can be changed. Don't get me wrong i am very satisfied with Bachmann products, just a suggestion on how to make it a little less frustrating.

Again thanks to all for the help.

Thanks to all, it worked. the paper work that comes with the Engine should explain were to find this information, its pretty vague. its like the don't want you to know every thing the decoder is capable of.

Again thanks to every one for the help.

Thanks, I finally found the user guide.

Thanks that worked, next ? can you set the automatic horn for reverse and forward?

Thanks

I have the Bachmann DD40AX sound value.
I can set all cvs except the cvs 193and 194 (bell on set point and bell off set point) i have tried the
default values of 05 and 10, i am using a Digitrax Zephry,  again I can change all other cvs but those two.
