MS sound decoders for large scale (0, 1, G, 2,...)

REAL 16 bits audio - 22 or 44 kHz sample rate - 16 channels - 12 Mbit memory - Multiprotocol: DCC, mfx*, MM

The first sound decoders of the "MS" generation were introduced in 2019 as successors to the MX decoders that have proven themselves over many years. The MS large-scale railway decoders in turn will now gradually replace the previous MX large-scale railway decoders as flagships of ZIMO technology. 

The core of the MS sound decoder is formed by a "state-of-the-art" 32 bit ARM microcontroller with DSP features and generously dimensioned memories. This enables sound reproduction in the highest quality (see subtitle above) and full mfx capability (including registration with Märklin digital command stations); there are also large reserves for future further developments (almost half the program memory is still free in mid-2021).

Note: Currently only MS-SOUND decoders are available!
For non-sound decoders the types of the MX range are still available. Of course there will be a changeover in this area as well, especially because it is necessary for mfx control. However, the differences between MX and MS will be less significant for DCC control than for decoders with sound.

Click on this symbol to expand the respective table row: the meaning of the data in the table and the properties of the individual decoders are explained by background information and application notes.

If you move the mouse over the pictures of the respective decoder, an info area with further pictures appears for selection.
You can also drag the open field and thus keep it open to compare different decoders.
