MRC Fortifies Its Prime Mover Leadership In N-Scale Sound

MRC continues its exclusive breakthrough in N-Scale sound: the F3 Dual-Mode (DCC & DC), Diesel Sound Decoder for Kato’s F3 & similar chassis Locomotives*.

Following MRC’s latest N-Scale Dual Mode Sound Decoders: the 0001644 (for Kato’s SD70MAC/AC4400 locos) & 0001645 (for Kato’s P-42 Genesis/EMD-E8/EMD E-9 loco’s), MRC has created another miracle of N-Scale decoder engineering: The snap-in F3 Dual Mode Sound Decoder.

With no connectors, no wiring, no machining, no “dremeling”… it’s an easy decoder installation! Remove the loco body, unclip the factory circuit board, drop in the new decoder, insert the clip and put the body back on.

MRC’s Brilliance™ sound, miniaturized to a single snap-in decoder with board-mounted super-fidelity speaker, is virtually “plug ‘n play.” Just imagine… the diesel engine sound, plus all 28 NMRA available functions, and your choices of multiple bells & numerous horns and more, give life to your Kato DCC N-Scale locos.

We haven’t forgotten power pack users! Just like our other N-Scale sound decoders for Kato locomotives, MRC’s latest Kato F3 decoder is a dual-mode decoder so DC railroaders can get brilliantly synchronized diesel rumble sounds on their layout as well.

Not only that, but DC power pack users can also enjoy the full range of sound & control capability of this newest N-Scale sound decoder when coupled to MRC’s unique & exclusive BlackBox (item 0001050) control unit.
