2 Digital Sound Decoder Owner's Manual
DSD FEATURES AND SPECIFICATIONS
The Digital Sound Decoder is designed to be installed onboard a locomotive in conjunction with a miniature speaker
to provide the ultimate in realism and control. The DSD integrates a full featured digital sound system, a Hyperlight™
and a DCC decoder into a single miniature electronic module. The modeler is thus freed of the expense and frustra-
tion of trying to fit multiple pieces of equipment into an often space limited locomotive. The Digital Sound Decoder is
compatible with the latest NMRA DCC Standards and Recommended Practices.
The DSD is available with prototype-specific sound and lighting effects for a multitude of North American and foreign
locomotives. Depending on the effect, the sounds are generated continuously, automatically in response to some
other action, or as controlled by the user. Additionally, certain sounds can be modified using specific Configuration
Variables (CVs).
Decoder Features
Compatible with the latest NMRA DCC Standards and Recommended Practices as defined by S-9.1, S-9.2, RP-
9.1.1, RP-9.2.1, RP-9.2.2, RP-9.2.3 and RP-9.2.4.
Supports 7 bit address modes for compatibility with ‘simple’ systems.
Supports 14 bit address modes for addressing any locomotive number up to 9,999.
Supports 7 bit consist addressing.
Supports Function Mapping.
Supports paged, register, and direct mode CV programming.
Supports ‘Operation Mode Programming’, allowing many CVs to be changed on the mainline without using a special
programming track.
