HO N DCC Sound TSU2200 Decoder EMD Diesel (TUC885005)

TSU-2200 Tsunami2 DCC Sound Decoder for HO-scale EMD Diesel Locomotives is a versatile, compact sound module designed to fit a wide range of HO to S scale models, delivering authentic diesel engine sounds and a convincing cab experience. The decoder provides crisp audio and interactive features that Tsunami2 decoders are known for, helping modelers recreate the feel of operating EMD diesel power on the layout.

Dynamic Digital Exhaust (DDE) adds realism by adjusting exhaust sounds to match throttle and grade, so flat runs stay steady while climbs bring deeper exhaust as more power is applied. A high-quality sound library includes 10 exhaust chuffs, up to 12 bells, and 90 whistles, along with additional cues such as couplers, dynamos, and cab chatter. Realistic operation is complemented by functioning brakes, adjustable exhaust cut-off, and firebox flicker, delivering an engaging diesel experience across HO- to S-scale models.
