DCC Sound Decoder Installation N Scale

Share it with your friends Like

In this video I want to show you a DCC Sound Decoder Installation in N Scale. I actually install 2 decoders in 2 Kato locomotives in this video–one motor only and one sound. Both are Digitrax deciders and one requires some home milling of the frame for the speaker.

Craig Snyder says:

Thanks for this video. I have installed the motor decoders before but have not done sound. After watching your video, I just might try it with one of my locomotives. Looking forward to the video on speed setting and rule 17,

EJ&E Jeff says:

Great how to video Ron! Just a couple things I would recommend. While the engine is apart, it's a good time for some teflon lube on the gears, and light amount of conductive lube on contacts. Second of course would be an ESU decoder w/ sugar cube speaker, no milling required

will kling says:

I am just wondering programing on the main….if you had another loco on tghe layout if you program the new one will it not effect the other? like the idea of putting the dc board in the jewel box. I do plan on installing a sound decoder and , is the same technic good for atlas locos? I drill out my frames with the dremel drill press with the apropriate cutting bit. works very well. good video

Zane's Trains N Things says:

Great install video. Thanks for sharing.

Dwight of Northern Star Railroad Lines says:

Thanks, brother, nice work, why Digitrax? Was ESU too expensive? Soundtraxx? Wish I had that wireless controller, my MRC is great, but a wireless would be fantastic…

Ainsley Perry says:

Ron, 15,000 subscribers, Big "UP'S" to you.Nice to see the replacement decoders installed with no hassle at all. Before re-conecting anything did you have to wash the basic chassis to clean away any swarf left behind? Even my fat fingers might be able to do this. Cheers, Chris Perry.

Daniel Hulitt says:

An informative video even for a DC guy. You talked about laying things out in the order of disassembly. I would also suggest that a photo before each subsequent step would be useful, and with the phones of today, almost everyone has a camera in their pocket.

John Arthur says:

Hi Ron, great video. You make it look easy! I assume you are using your new soldering iron here, curious as to what power setting you are using when soldering to a decoder. thanks.

Crazy SDK says:

My phone vibrated in the wee hours of this morning and told me that this video was posted. The timing was perfect because I had literally just finished putting the shell back together on an Atlas N SD-50 that received a loksound (it put up a pretty good fight). The timing made me laugh, but I was too tired (from fighting all night to install the decoder) to watch it until now.

Tim Shobe says:

Great Job of installing! the first sound decoder you need to mill out the fuel tank for the conpastor. and then you need to use a speaker baffle to direct the sound out. I don't like that one with the long speaker on it, it's not as loud. the last one with the round speaker if you take some tape and put it over the front of the speaker and drive the sound out the back. And mount if face down just like you did . It makes it about 10 times louder and on the fuel tank I drilled out the 1/2" hole and then put a screen over the hole to keep out the big stuff. Give that home made speaker baffle a test and see if it works better for you. Thanks for all the great videos, I find my self sitting by the computer waiting for your next one to show up!

Bruce Giroux says:

Nice work Ron. Thanks for posting your guide.

Reid's Train Stuff says:

Great install video Ron, should help with future sound decoder installation, plus looking forward to seeing how you put rule 17 on a Digitrax decoder, can do it on NCE and TCS, but never worked out Digitrax ???

Adrien Gadson says:

If these manufacturers would use a 4 ohm speaker instead of a 8 ohm the sound would be louder. Also you could add a second speaker in parallel which drops the impedance of the 2 speakers to 4 ohm each and takes less power to operate them. This is simple car audio knowledge. Also you could drop a bead of epoxy to set the back of the speaker in the chassis.

Joe G says:

Wow, great jon, Is that a common amount of work to instal sound into N scale?

paul turenne says:

Very useful video Ron.I find these types of "how to" tutorials one of my favorites ,you can never have too many decoder installation videos.Keep up the great job.

Joseph Carlino says:

Excellent video Ron. As usual, your method of instruction coupled with the way you capture everything on camera is extremely useful and informative!! And I'm an HO scale modeler…

Deltabravo604 says:

Very good information. I wish you had killed the music earlier when you tested the sound decoder.

Dean Halls says:

Hi Ron, nice and informative video however may I suggest that if your doing things with sound locos or scenery sounds you drop the usual accompanying background sound as it completely blotted out the loco sounds on this video. Looking forward to your next output.

Kind regards Dean

Michael says:

This is way more complicated than I thought.

Florent says:

When I see that most decoders are not really plug and play, the work required by the installation and the most often, the poor quality of sound, I wonder if it is worth investing in adding sound decoder? Is it not better to buy factory equipped?

echo arty says:

first off, grats on the 15k Sub's. Cool vid, greatly looking forward to the Speed matching. And as I have no idea what 'rural 17 lighting' is, it will be very informative. 🙂

Mr. B's Hiawathaland Rails says:

That was real helpful. Ya sure made it look easy. Mr. B.

Danny Ervin says:

Thanks Ron, Just purchased my first locomotive and digitrax decoder. A SD70ACE with the exact Digitrax decoder you used with the non-sound installation. I was worried about my installation once they arrived, but no longer. Many thanks for your videos! Probably be awhile before I attempt a decoder with sound.

david greenwood says:

Hi there everyone, I just purchased a new Kato ICE 4 train and Kato decoder for it. when I installed the plug and play type decoder I programmed it using the intellibox2, however when I run it, it runs unevenly like it surges in speed the slows off then surges again. I haven't installed the accessory decoders for the change direction red and white lights yet as I am awaiting delivery could it be that is part of problem, was just wondering if anyone out there has encountered a problem like this.

Robert Hawtin says:

Yes, tricky fitting that speaker without a mini or micro milling machine (look at 'Proxxon'). But those are expensive, so three tips: Start by using a smaller 'four facet ground' drill (use Google for details). It is much less likely to wander. Then gently open the hole up with successively larger drills. Buy something called an 'end mill' in the same size as your final drill size. Use this to give a flat bottom to the hole but take care not to increase the central depth. Do not try to drill the initial hole with any end mill – it will skate about all over the place if both it and the workpiece are not held firmly in a proper milling machine. Finally, buy some suitaby sized drill stops. These are metal rings that clamp on around your drill bit and prevent you drilling too deep – all to easy to do. Using a small precision drill stand would also be a good idea and they are not that expensive. They give much better sideways and depth control than can usually be achieved by hand. This job is not for the faint hearted! Maybe find a friendly small engineering shop and buy them a beer or two. Good luck. BobUK.

Angel mora troncoso says:

Hi Ron, how are you? Great video. Thank you very much for your contributions. Some time ago I bought 3 digits digitrax SDN144K1E, which I installed in three kato locomotives, GG1, SD40-2 and AC4400. In all three cases, when the sound is not deactivated, the docoder restarts within a few seconds of activating the locomotives. I was told that it could be caused by bad welding contacts, but by deactivating the sound, the locomotives work very well. You can help me find the problem, it is a shame not to be able to use the sounds. I use a central digitrax db150. Thank you.
