DC Sound Systems - Model Railroader Magazine

I have several DC sound engines in steam and diesel. Broadway Limited , Atlas, Athearn, and Proto,  The DC/Dcc systems are QSI, MRC, Blueline, and Paragon , Paragon II. They all work very well. I am happy with them all. 

The MRC uses  a handheld controller with remote. Not the best but OK.

For the QSI, Blueline, and Paragon systems you will have to add a sound controller to your exixting Power pack for the most sound and programing. Around $39.00 .  I also think these have the best sound.
