Description
A LokSound 5 on the keyed 21MTC “MKL” interface — the variant fitted to certain Märklin® H0 and 0 models, mechanically keyed so the decoder seats correctly where a standard 21MTC board would not. Electrically it is a complete LokSound 5 and ships with an 11 × 15 mm speaker and sound chamber.
You get the same 16-bit, 10-channel hi-fi sound engine, 3 W Class-D amplifier and 128 Mbit memory, plus a load-compensated 1.5 A motor controller with AutoTune. It speaks DCC/RailComPlus®, Motorola®, Selectrix® and M4, handles Märklin® / ZIMO® HLU / Lenz® ABC braking and runs on analogue DC and AC.
- Interface: 21MTC MKL (keyed)
- Protocols: DCC (RailComPlus), MM, SX, M4
- Scale: H0, 0 · 1.5 A motor
- Supplied with: 11×15 mm speaker + sound chamber
