Items used

ESU 58429 LokSound 5 DCC 21-MTC decoder

DCCSound Premium speaker to suit 422 class (2013 or 2019 production)

2013 release

It's a simple plug-n-play solution for sound. Remove the two coupler assemblies then gently lift the body off from the chassis. Splay the shell sides out and remove the body.

Fit the decoder and speaker, ensuring no fine wires are crushed around the speaker area and that the decoder is orientated correctly when fitted.

Also, ensure the 3 pads on the Auscision motherboard are clear of objects as the body has electrical spring contacts which must make contact with the pads. In the image below Kapton tape has been used to secure the speaker wires away from the pads.

Finally, refit the body, couplers and test operation.

2019 release

The 2nd production run chassis design is configured such that the speaker is mounted at the # 2 end.

Compared with the 1st production run, the decoder is now mounted upside down, known as NEM660 compact mounting.
