This replaced the MX658N18 decoder, this is only offered with a Next18 plug.

MS-Sound with a fully digital sound amplifier of 1 W for 8 Ohm speakers.

Stay-alive: the internal tantalum capacitors (2000 µF, 5 V) can be extended externally, by further tantalums or two gold caps (in series), recommended: ZIMO MINIGOLD (150 000 µF, 5 V).


DCC addresses 1 – 10239, consist addresses 1 – 9999, MM addresses 1-80, functions F0-F28
14, 28 or 128 external speed steps, 256 or 1024 internal steps
Programming CVs in “Service Mode” (on the programming tracks) and in “Operational Mode” (with RailCom for feedback and acknowledgements), using mfx, if available
Driving operation without interruptions (without decoder reset or restart) after losing contact to the rails for 1 or 2 seconds (even without external stay-alive capacitors)
Automatic continued operation if the wheel/track contact is interrupted until the supply is restored (if sufficient energy storage – “Stay alive” – is available in locomotive; see section “ENERGY STORAGE, below)”).
DC and AC analog operation, the latter including direction reversal through Märklin-typical overvoltage pulse (up to 35 V)
Updateable software: new software versions are loaded into the decoder without opening the loco, via flash drive with the decoder updating and sound loading device MXULF/A or with the central controller MX31ZL, or directly from the computer via ZSP (ZIMO Sound Programmer) and MXULF or MX10 (planned)
