The LokSound 5 is the most important member of the LokSound family. Due to the combination of the digital decoder and the sound module on one circuit board we achieve the smallest possible dimensions of 30 mm x 15.5 mm. Therefore, it fits into almost any H0 or O-gauge locomotive.

A LokSound 5 DCC Micro decoder is expected in 2022, with a form factor suited to various N Scale locomotives.

These decoders are supplied blank for the dealer to install the sound file of your choice.
