Install Tsunami Sound in Athearn Genesis GP15-1

[torikoos]

Hi Koos, that's a nice video explaining all the steps. It is basically very similar.
I noticed two differences
a. your speaker has a closed backside and works without a baffle. Mine has an open backside and needs to reside in a baffle to prevent an acoustic shortcut.
b. the Tsunami Athearn drop in Tsunami have 1.5 V bulb support only. That's fine if you like the bulbs. I do not and have most Athearn engines replaced with LED. LED will not work with 1.5V properly. They are rated for current but for simplicity you can assume 3V is the right voltage. I did therefor order "universal" instead of drop in decoders for my MP5AC LED equipped machines.

Thanks Reinhard, alternatively, you can use the 12V output on Tsunami decoders. The only thing to do then is to add resistors to your outputs, and solder the LED's to those. In small loco's this will take up a bit more space, and it's why I like the Loksounds because of the build in resistors.

This video shows it in operation, and you can see how bright the LED's are.

I did select a different sound file after this video was made as I did not like the beeping noise at engine start up and shut down. This early recording must have been made with a microphone in the engine compartment, where a warning buzzer is fitted. The other sound file I now use does not use that beeping sound.

One more: <!-- m --><a class="postlink" href="http://youtu.be/ipL9QMpppqQ?list=UUiKMM02w8vLf0WSnbNWIelQ">http://youtu.be/ipL9QMpppqQ?list=UUiKMM ... WSnbNWIelQ</a><!-- m -->
