ESU equipment



Made in Germany, has BEMF and sound, sounds can be downloaded, modified. 8 bit sound unit, 4 sounds at the same time.


check out the yahoo group on this one.

ESU uses an 100 ohm speaker, a good thing is that it does not need a dc blocking capacitor. Users have reported that is seems to work ok with with 2 Loksound speakers in parallel, and even with 2 in parallel and a third in series.

Be sure to download the manual from LokSound, but it's still not straightforward. I'd recommend using DecoderPro.

Right out of the box, the sound starts out at max, and can be the reason many people report the sound is distorted. The horn volume is also set way too low.

There are 3 sound controls, overall, horn/whistle, and auxillary. The engine sounds are tied to auxillary volume control.
Try setting the aux volume someplace between 50% (dec 32) and 75% (dec 48), values allowed go from 0 - 64. Then set the horn/whistle to max, and the same for overall volume.

Do you need the Loksound programmer? There is no diesel transition in the emd decoders. Some people have used the programmer to create transition sounds. The programmer includes a free *.wav extractor and a *.wav file editor. You create a transition sound and place it the LokSound project in a position where the transistion occurs.

They have good sounds, ability to customize the sound, resistant to drop outs, good motor control.

They also have sounds that change according to load, like the SoundTraxx Tsunami.

ESU - LokSound notes

They have CV's above 255, you set CV32 = 1, and then set CV 275 (example).

One of the features I don't like about them is the fact that I don't seem to be able to play the whistle and produce whistle signals. It only plays the sound loop in the decoder unlike the Soundtraxx decoders where one can produce a short toot or long depending on how long the function button is pressed.

Using the Lokprogramer,I put horn/whistle initial wav and exit wav into another sound slot then map that slot to function 3.I then have long whistle on F2 and short whistle on F3.
