These virtual drop-in decoders take MRC’s industry leading technology and miniaturization to the limit. The most simple N-Scale installation imaginable: Remove the loco body, lift out the factory circuit board, add a few pieces of insulation tape and replace with the MRC sound decoder /speaker combo… put the body back on. No wiring needed. The decoder is equipped with MRC’s world renowned Brilliance sound, miniaturized to a single drop-in decoder with included super-fidelity speaker, that’s virtually plug-n-play. MRC’s true, live capture, full fidelity sound including diesel rumbles, actually recorded by MRC’s Sound Engineers from real diesel locomotive prime movers. Just imagine all 28 NMRA available functions, and naturally, MRC makes available multiple horns, eight-bells, brakes, air releases, pop valves, cooling fans, coupling sounds and more. Directional lighting is included to give life to your Atlas SD50/60 locos.
