DCC Sound Volume Controls

Geoff asks readers:

“When you buy a loco with DCC and Sound equipped is the sound volume adjustable to set the level to increase when the engine’s speed increases. I don’t want loud noise at the same time from multiple engines on the track.”

  • Hervey says:

    I have never seen a decoder that is designed to allow you to easily increase volume as speed increases. There is a way of doing what you want though. You have to enter programming on the main mode and adjust the corresponding CV. While doing this though you have given up control of the train until you get out of the programming mode. If you are running multiple trains at the same time this could rather hectic to say the least. You may be better having all locos that are sound equipped set to a volume level that is a compromise between idle and hauling speed.

  • Frank B says:

    The decoders automatically change the chuff rate (steam) or engine tone (diesel) as the loco increases speed.

    Any increase in volume is only proportionate to the real thing, not excessive.

    The various sound effects, such as bells, whistles and brakes etc, can each have their volume level set individually.

    For precise specifications, the technical manuals for DCC decoders and control systems are usually available for free download from the manufacturer’s website.

    Sound – Hmm. Just remember that most people run their locos TOO LOUD. Go into the real world and notice how the sound changes as the train approaches, and again as it disappears into the distance. In the real world you might not notice a loco’s sound until it is quite close, and it fades equally quickly once it’s passed. In HO (1:87) you should not hear a loco that’s idling away 6 feet away (Nearly 200 yards). So keep the noise down for your own sanities sake, for as you say a few engines idling, with the volume up is a pain.
