With Speaker Requires 8 Ohm 1 Watt 

The Speaker:
The Speaker we sell comes from (cell Phones) it is small but also quiet and has a rather poor sound quality and will therefore only work in quiet applications. It is honestly more a "test speaker"

Good speakers will make the module sound louder by 300% and also improve sound quality. They have a enclosed housing and will be larger, they start at $10-$20 (like the ESU from Loksound modules). Unfortunately since the pandemic they are hard to come by in a reasonable quantity so we can't offer that option but you find one or have a 8 ohm , min 1 Watt speaker it will work.  
With these modules it is possible to add sound function to a locomotive who has a decoder with aux switch function.
We have other sound boards for any locomotive. There is a choice between different horn sounds and steam whistles, you can also choose large or small speakers or no speaker.
Look in our other items for sale. In doubt just send us an email.
   
This is a simple Horn sound of a old US Diesel style diesel locomotive. It is designed to be used on any locomotive old new digital decoders or analog either AC or DC.
We also have a different version (slightly smaller and cheaper) which can be used in any modern 21 pin decoder. 

Sound Sample Video:
Old US Diesel Horn Sound



Marklin 60972, 60982, MLD or MLD3, DCC and ESU newer style. (Aux switch functions 21 pin)

 

Wire one of the black input leads to pin 16 +UB ( Orange Marklin, Blue ESU). The other black wire goes to either available Aux Port. AUX1 (Pin 15), Aux2 (Pin 14), Aux3 (Pin 13), Aux4(Pin 4), Aux5 (Pin 17)

 

Marklin 60760 or similar decoders (only one light switch function) most cheap decoders.

 

These decoders have 2 wires going to the head light. In essence the sound module will just be paralleled with the front light.

Wire one black wire from the sound module to one of each of the wires going to the light.


DC 2-rail analog operation:

Connect one black wire to the left track feeder, the other to the right track feeder.

 

 

AC 3- rail analog operation:

Connect one black wire to the rail connection Chassis ground. The other black wire goes to the pick up shoe connection (mostly the light bulb socket works well).

 

 

Here in essence the Sound module is just connected to the track power directly. The sound will play once the power exceeds 5V and then stops playing until the train stopped for 1+ seconds before playing the sound again.
