N Scale MRC is excited to release another breakthrough in N-Scale sound: the 1808-V2 Diesel Sound Decoder for Kato SD80 Taking miniaturization and MRC's industry leading technology to the limit, this DCC/DC sound decoder is 100% drop-in! The most simple, straight-forward, N-Scale installation imaginable.... Remove the loco body, lift out the factory circuit board 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 BrillianceTM sound, miniaturized to a single drop-in decoder with included speaker, that's virtually "plug 'n play". MRC's true, live capture, full fidelity sound including diesel rumbles, actually recorded (railside) by MRC's Sound Engineers from real diesel locomotive prime movers.
