Hello,
I installed a DCC Soundtraxx Decoder with speaker in my Proto 1000 PRR C-Liner and put the speaker in the rear above the trucks in the metal frame. How do I make the sound come out of the Engine so it is louder?
Any suggestions please?
Thanks,
Greg
I’ m not sure how you would do it to a deisel, but on my steam locos the speakers are installed in the tenders
and I drilled ALOT of little holes in the coal load with a #65 drill bit. I’m not saying to drill holes in your loco,
but I think the shell is acting as a muffler.Try Soundtraxx web site, they offer some installation ideas. Dave
You didn’t say but I’m assuming you didn’t enclose the speaker in an sealed box. If you look in the directions that came with the soundtraxx mod there will be directions on how to enclose your speaker. Even a small enclosure will greatly increase the sound. I know with diesels theres a limited space, some people will put the speaker in a B-unit, this will give you the space for a good size enclosure and a good size speaker. Remember the bigger the speaker the better the sound. Also make sure you connect the + wire from the mod to the + side of the speaker. If you don’t know which side is the + side there are directions on soundtraxx web site. Good luck!
Yes, I enclosed it in a specker enclosure. I might drill or cut a door hole in the rear or drill holes underneath to let some sound out.
Thanks,
Greg
Greg, cutting a door or drilling holes would only defeat the purpose of the enclosure. Its suppose to be air tight. Did you check to see if the wires are connected right. Remember the + wire from the mod goes to the + side of the capacitor then from the - side of the capacitor to the + side of the speaker. If you don’t know which terminal on the speaker is + use a single AA battery (1.5 volts). Connect the speaker to the battery and watch which way the cone moves. If the cone moves out , the wire from the + terminal on the battery is connected to the+ side of the speaker. If the cone moves in then the wire from the + side of the battery is connected to the - side of the speaker. Mark the + terminal on the speaker and reconnect to the mod. Are you useing a 8ohm speaker? Did you change your CV for volume. Let me know what happens.
As long as the speaker itself is enclosed from the backside you will be fine. Have you tried increasing the
volume? Adjust CV 120 for horn volume, CV 121 for bell volume, and CV 122 for exhaust volume.
They come set from the factory at a value of 128. That’s half volume. You can set the volumes up
to a value of 255. Dave
Hello,
Where do I adjust the CV 120 for horn volume, CV 121 for bell volume, and CV 122 for exhaust volume. On the Digitrax Transformer mode on the program track? I can change decoder numbers, but never did anything else.
Thanks,

You should read your Zepher manual. Section 16 explains about programming the decoder.
If you haven’t already downloaded the manual for your decoder from Soundtraxx, definitly
do it. It will explain each CV and their purpose. Let me know if this helps your problem. Dave
