I used a Electric RR's Sound Commander board. This was using a first generation experimental version of the Sound Commander which is being released as an improved more versatile and powerful version. The size will be similar to the one used here. |
| This installation was to prove the design of the small speakers for S gauge locos as well as to demonstrate the new Sound Commander's potential. The Sound Commander's small size makes it very versatile. |  |
 |
Here is the early version of the Sound Commander board. It is fastened to the roof of the shell with double sided tape. The Sound Commander can be changed to a steam whistle by adding a jumper on the board. This version only has the Bell and Horn/Whistle sounds but the production version will have more sounds and can be upgraded in the field by changing the sound chip. |
| Finding speakers to fit and still make a decent sound is a challenge. I found these tiny 1" x 1/2" oval speakers at Jameco Electronics. Part number 307854. |  |
 |
By combining them in an assembly I was able to get the size and volume that was acceptable. I Glued them side by side and added pieces of Plastistruct as spacers and to give them added strength. The assembly just fits in the body and give it a sound chamber to resonate with.. |
| Bottom view shows that I removed most of the connector pins for clearance and soldered the wire to them directly wiring them in series. |  |

This board will give the AF operator a wealth of new sound capabilities for Diesel, Steam and Accessories as new sounds are offered. For more information on the Sound Commander visit the Electric RR web site.
