N DROP-IN: KATO SD70MAC & AC4400 (16-bit)
Brand: MRC
Item # 0001960

This MRC N-gauge dual mode Drop-In provides the easy installation
of a one piece sound decoder/speaker combination that replaces
the factory installed printed circuit board for Kato SD70MAC and
AC4400, by simply removing the factory pc board and dropping in
the 1644 decoder.

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

We haven’t forgotten power pack users! MRC’s 1644 decoder is a
dual-mode decoder so DC railroaders can get brilliantly
synchronized diesel rumble sounds on their layout as well.

Decoder only - locomotives not included

* Note: interior of the body shell must be modified to
accommodate the height of this decoder
