Doehler & Haass SD22A-2 - Vehicle sound decoder (Gen3)

Doehler & Haass SD22A-2 - Vehicle sound decoder (Gen3)

 

Technical details

Vehicle sound decoder SD22A for SX1, SX2, DCC and MM (3rd generation)

Product features and functions
For optional operation with conventional DC driving devices, digital systems according to SelecTRIX 1 and 2 or according to DCC format
Switching between analog and digital operation is automatic
In digital operation, the last programmed system is used (it does not switch automatically!)
SelecTRIX 1 31 speed levels, 100 addresses
SelecTRIX 2 127 speed levels, 10,000 addresses, 16 additional functions
DCC short addresses (1-127), long addresses (0001-9999), with 14, 28, 126 speed levels
Load control of the latest generation, resulting in particularly smooth control behavior
Various Control variants for optimal adaptation to the engine
Internal 127 speed levels
Adjustable engine frequency (low frequency, 16 kHz, 32 kHz)
Block section operation with simple diodes in digital mode
Light and function outputs can be dimmed and activated analogue
Shunting gear
Engine, light and track connections can be exchanged electronically
All function outputs can be freely programmed
Temperature protection
Original vehicle-specific steam, diesel and electric locomotive sound projects (no "standard sounds")
Realistic steam driving sound with wheel-synchronous and overlapping exhaust beats, speed level-dependent pitch and independent boiling sound
Realistic diesel-hydraulic driving sound with speed level-dependent pitch, variable idle speed and independent acceleration levels, turbocharger and dynamic brake
Realistic diesel-mechanical driving sound with several gears, idle, several driving and acceleration levels and possible switching noise
Realistic electric driving noise with traction motor and traction motor fan as well as setup noises (pantograph, main switch, etc.), switchgear noise and dynamic brake
Bell, horn, whistle, closing doors, etc. (depending on the sound project) can be triggered separately at any time
All sound sequences can be freely configured ("function mapping") and triggered randomly
Speaker connection protected against short circuits and overloads
Low heat generation through the use of the latest technologies
Reset function for DCC and SX2
Decoder can be updated
Sound projects can be loaded via SUSI interface using a programmer

The SD22A vehicle sound decoder supports braking with asymmetrical digital voltage (four diodes in series and one diode antiparallel, Lenz ABC), slow travel (with suitable brake modules) and bidirectional communication (Locomotive address feedback in DCC operation, RailCom®).

The SD22A vehicle sound decoder does not support SX1 programming. Please set up SX1 operation using SX2 parameter programming.


If you wish, we can also program a sound project for you for an additional charge. Please feel free to ask us about this without obligation: kundenservice@modelleisenbahn-shop.com
