The circuit board has been developed for the Märklin and Brawa locomotives of the VT 133 ‘Schweineschnäuzchen’ series and fits exactly in place of the original decoder.

Despite the limited space available, this adapter is also suitable for sound decoders.
The n18 version is suitable for decoders with a NeXT18 interface. The n18 version offers the advantage that the decoder is practically invisible through the windows of the locomotive.
The connections Aux5 to Aux6 are amplified by a chip, Aux 1 to Aux 4 are routed directly to the corresponding consumers.
With the mtc version, a decoder with amplified Aux3 and Aux4 must therefore be used at the interface (ESU decoders with ‘MKL’ in the designation).
