4Sounddecoder from firmware version 1.12
1 Introduction
The sounddecoders are compatible with the protocols of SelecTRIX standard SX1 and SX2 as well as with NMRA-DCC and
MM1/MM2 standard. They and can be operated by every central unit supporting one of these data formats. They can be
used for normal direct current motors as well as for coreless motors.
Operation on alternating current layouts with switching impulse is not allowed!
The switching impulse destroys the decoder!
Exception: SD21A and SD22A
2 Safety instructions
This product is not suitable for children under 14 years.
It might be swallowed by children under 3 years!
An improper use involves a risk of injury due to sharp edges and points!
3 Warranty
Every sounddecoder is fully tested before delivery. Should nevertheless a failure occur please contact the dealer where
you purchased the decoder or directly the producer (Doehler & Haass enterprises). The warranty period is 24 month from
the date of purchase.
4 Support and help
In case you have any problems please contact us by email: [e-mail]
Normally you would get an answer within a few days.

Sounddecoder from firmware version 1.12
5.1 Driving operation
• Operation can be controlled either by conventional DC command station or by digital central units supporting the
formats SelecTRIX 1 and 2, NMRA norm (DCC) or MM1/MM2 standard
• Automatic switchover between analog and digital operation
• In case of digital operation the last programmed system will be activated. Automatic switching into a certain
operating mode is not possible because of the multiprotocol operation. For switching a parameter (e.g. locomotive
address) is to be readout and must be written again in the required operating mode. Thus the switching to the
required track protocol is completed.
• SelecTRIX 1..... 31 speed steps, 100 addresses
•SelecTRIX 2..... 127 speed steps, 10.000 addresses, 16 additional functions
•DCC................. Short addresses (1-127), long addresses (0001-9999), with 14, 28, 126 speed steps
•Load control state of the art, that way an especially smooth regulation behavior
• Various regulation variants for an optimal adaption of the motor
• 127 internal speed steps
• Adjustable motor frequency (low frequency, 16 kHz, 32 kHz)
• Block system operation with simple diodes in digital operation
•Outputs for light and function dimmable and can be activated analogously
• Shunting gear
• Electronic interchange ability for the connections of motor, light and track
• All function outputs are freely programmable
• Thermal protection
• Reset function for DCC and SX2
•Decoder can be updated (programmer is required):
Incorporated sounddecoder can be updated when the locomotive is standing on track (no need to open the engine).
SW can be downloaded from D&H homepage for free.
• Asymmetric digital voltage brakes (four diodes connected in series and one diode anti parallel),
Slow approach (with appropriate brake modules) and bidirectional communication (locomotive address feedback
signal in DCC operation, RailCom®).

16 Sounddecoder from firmware version 1.12
5.2 Sound operation
• Originally designed sound projects for steam, diesel and electric locomotives (no “standard sounds“)
• Realistic steam sound with synchronized wheel and overlapping exhaust whams. Pitch is depending on speed
steps and independent from boiling sound
•Realistic diesel-hydraulic driving sound with pitch depending on speed steps, variable coasting speed drive and
independent acceleration steps, turbocharger and dynamic brakes
•Realistic diesel-mechanic driving sound with several gears, coasting speed, several driving and acceleration steps
and possible shift sound
• Realistic electric driving sound with traction motor and traction motor fan as well as upgrading sounds (pantograph,
main switch etc.), switchgear sound and dynamic brakes
• Bell, horn, whistle, close doors etc. (according to the sound project) can be separately triggered at any time
•All sound procedures are freely configurable (“Function Mapping“) and can be accidentally triggered
•Speaker connection protected from short circuit and overload
•Low heat generation through high tech
• Loading of the sound projects by programmer over SUSI interface (about 6 minutes). For this the locomotive has to
be opened and the sounddecoder has to be connected via SUSI interface with the programmer. For that appropriate
connecting adapters may be necessary. The sound projects can be downloaded from the D&H homepage for free.

Sounddecoder from firmware version 1.12
6 Installation of the sounddecoder
6.1 Preparation
Check if the locomotive is in perfect condition electrically and mechanically before installation. Defects or dirt must be
eliminated first. Pay attention to the instructions of the locomotive producer.
Only locomotives running smoothely in direct current mode should be equipped with the sounddecoder. New locomotives
should be run at least 30 minutes in each driving direction.
Before installing the sounddecoder all connections between the motor and the track connections have to be removed
(sliding contact, chassis, etc.).
Both motor connections must be disconnected from the ground!
Further on all capacitors have to be removed, particularly those associated to the connections of light and motor.
For fixing the decoder we recommend a double-sided adhesive tape.
With sound decoders, always solder the speaker first.
Carry out all soldering work in a de-energized state.
Avoid test drives with stripped unsoldered cable ends.

18 Sounddecoder from firmware version 1.12
6.2 Installation
There are following variants to connect the sounddecoder:
1 In case your locomotive is equipped with a 16/22 pin PluX interface:
The SD16A-4 and the SD22A-4 can be directly inserted into the interface.
2 In case your locomotive is equipped with a 18 pin/Next18 interface:
The SD18A can be directly inserted into the interface.
3 In case your locomotive is equipped with a 21 pin/MTC21 interface:
The SD21A-4 can be directly inserted into the interface.
4 In case your locomotive is equipped with an interface corresponding to NEM 651:
TheSD05A-1ortheSD10A-1hasalreadytheappropriateconnectionsforthisplug.Shorttheribboncableuptoapproximately5
mm and remove the rest of the insulation. The decoder can be now inserted into the interface without any problems.
For SD18A a N18-K-1 adapter is required. It has already the appropriate connections for this plug. Short the rib-bon cable
up to approximately 5 mm and remove the rest of the insulation. The adapter can be now inserted into the interface
without any problems.
5 In case your locomotive is equipped with an interface corresponding to NEM 652:
For SD18A a N18-G-2 adapter is required.
For SD21A-4 a M21-2 adapter is required.
They are equipped with the appropriate connection cable for this socket. You can connect the adapter with the in-terface
without any problems.
6
If your locomotive is not equipped with an appropriate interface, the sounddecoder must be wired individually. For this
you can either use SD05A-3 or the SD10A-3 or, when using other sounddecoder, the adapter N18-K-3, N18-G-3, M21-3
and P22-3, according to the type of the sounddecoder.
7
SD05A-0 or the SD10A-0 resp. the adapter N18-K-0, N18-G-0 and M21-0 should be used only by experienced model
railroaders, as the connection wires must be soldered directly onto the adapter.
For fixing the adapter we recommend a double sided adhesive tape.

19
Sounddecoder from firmware version 1.12
For installation variant 6 connect the wires of SD05A-3, SD10A-3 or of the adapter according to the following diagram:
red wire ........................ with the right track wire
black wire ..................... with the left track wire
orange wire................... with the motor wire, which was connected with the right track wire
gray wire....................... with the motor wire, which was connected with the left track wire

green wire .................... function output AUX1 *)
violet wire..................... function output AUX2 *)
blue wire....................... common return, up to 30 Volt (+VS) *)
*) Only N18-G-3, M21-3 and P22-3
For installation variants 4-6 connect:
brown wires.................. with the speaker
6.3 Check after installation
The first test should be executed in the programming mode (e.g. by reading out the address). In case of an incorrect
feedback (confirmation signal) to the central unit (“Error“), please check again the correct assignment of the connections,
resepectively if the motor is really disconnected from the chassis electrically.
