Loksound 5 sound decoder to suit the Heljan 104 DMU
Supplied with our recommended sound from one of our suppliers or you can select 'other' from the drop down menu if you would like the sound of a specific provider. You can add a note on the checkout page to let us know who's sound to use.
Choose either no speakers and use the ones built into the model, or swap these for a pair of thin tablet speakers for an extra £5, if you choose the upgrade the speakers need to be soldered.
