Sound decoder SD05A for SX1, SX2, DCC and MM

Doehler & Haass SD10A Gen 2 – Ultra-compact sound decoder for small models

The SD10A Gen 2 is the smallest full-function sound decoder from Doehler & Haass, specially designed for locomotives with extremely limited installation space—ideal for small H0 models, TT and N scale. Despite its tiny footprint, it delivers advanced audio performance with 22 kHz sampling, 16-bit resolution, up to 128 Mbit memory and about 760 seconds of sound capacity.

It supports all major digital formats (SX1, SX2, DCC, MM) as well as analog operation, and includes an integrated SUSI interface for updates and sound programming. With a maximum motor current of 1.0 A and supply voltage up to 30 V, the decoder is reliable even under demanding operating conditions.
