Mylocosound on DCC

I'm posting on behalf of Peter Lucas of Mylocosound who is unable to do so, due to ongoing problems in Australia with the forum. Here's what he has sent me:

Sarah Winfield’s thread about the new MyLocoSound Light Diesel soundcard made us think a bit harder about the use of our soundcards on DCC. No, we don’t have a sound decoder…but we don’t need one. Our existing soundcards, universal steam, diesel, electric and the Light Diesel, will all work perfectly well with basic, non-sound decoders like the Massoth 8154501. The attached diagram shows how. Wiring is simple and, best of all, you don’t have to fiddle with any DCC addresses or CVs to make it work. The rechargeable battery keeps the sound going when the loco is stationary and will be recharged automatically when the loco is running. The key to the simplicity is the automation which can be selected in the soundcard. For example, a light diesel can be set up to start the engine when the throttle is give a small tweak, an airbrake release and a horn blast on moving off, a timed horn when running, a brake squeal on stopping and engine shut down after a minute of inactivity. All of this can be set to happen automatically using a TV remote control. The universal steam, diesel and electric soundcards all have similar automation facilities.


For those who are more knowledgeable about DCC, there are more advanced options. The battery can be discarded in favour of connecting to the decoder’s constant voltage output in the range of 8v to 22v. If you know how to handle CVs, the horn, guard’s whistle, engine start/stop, etc can be triggered by the controller buttons using the function outputs or servo outputs with a servo switch.


The result is that you can upgrade a DCC loco to sound for under seventy pounds (including speaker and TV remote control) compared with switching to a sound decoder which can be three times more expensive.

So, it would be worthwhile to mention (and I realize this is true) that the Mylocosound sound unit will not be "confused" by the PWM normally sent to motors by remote controllers. Not all sound cards can do this. This is a good feature.

The other thing that would be helpful, is to realize that there is really not a "constant voltage output" as standard on DCC decoders. Often rectified track voltage is available, but it's not normally identified as such, although for all intents and purposes it is constant.

There's often a regulated 5 volts available, but the current limits may be too low.

So, can you specify the maximum current drain of the Mylocosound decoder, at max volume and how this varies (if at all) between 18 volts and 24 volts?

All this information is helpful when fitting to a DCC decoder.

Thanks,

Greg
