If you want CTC modules to also inspire with sound, you must rely on existing digital technology. By now, there are several possibilities to do this:
- CTC locomotive modules can generate a DCC signal. In this way, either the digital decoder that came with the locomotive can be continued to use, or a new digital decoder can be connected. You can find more information about this in Chapter 8.1 - “Old Digital: Integrating DCC Decoders”
- From the firmware (20230902) supplied with CTC App version 4.19, the SUSI3 interface can be retrofitted for all CTC locomotive modules (except for CTC-Lokmodul-H0a). For locomotives that have originally used a SUSI3 module for the sound, the original sound can remain, without the need to keep the original decoder. This can be done, for example, with PIKO’s G scale model of the BR50. Learn more about SUSI sound in Chapter 9.1 - “Sound with SUSI Interface”
