BLANK Sound Decoders (with factory/test sound only)

Zimo sound decoders are the industry leaders in terms of features, performance and reliability. All Zimo sound decoders provide the same set of features varying onlyin their physical attributes such as size, motor power output, and number of function outputs.

Which decoder should I choose? Well, this depends on the scale and model you are installing into, how much space you have, and if there are any specific features you need. Contact YouChoos if you need help.

Prices listed below are for factory-default decoders (for no extra cost, choose any YouChoos sound project to have loaded - browse from the sound list rather than here to do this). Speaker is not included.

Standard Decoders

Standard decoders mean that you can control motor and one or more auxilliary/function outputs (for lighting, smoke etc.). These are NOT sound decoders. Choose based on size, motor power output, and required outputs.

Zimo standard decoders are probably the best available for fine motor control and offer a variety of CVs to assist in tuning outputs to get the best from your models.

Ask if you need help choosing! YouChoos holds stock of most of these decoders.

Function Decoders

Function decoders offer ONLY auxilliary/function outputs, and DO NOT have output for controlling motor or sound.

They have a wide variety of applications, but most commonly used to add lighting, smoke, or auto-coupling control to a vehicle that has no motor. For example, many modern steam locos have a DCC decoder socket in the tender, which gives control of the motor, so a separate function decoder can be added in the boiler of that loco to provide control of loco lamps, firebox glow and other special features.

Another common use is to provide DCC control of coach lighting, which is particularly effective where the decoder supports a stay-alive capacitor which helps eliminate flicker.

Accessory Decoders

Accessory decoders are static decoders on your layout, deployed to control points and lighting features. Some allow control of solenoid-style point motors, and others give fine servo-control for slow-action points. You need a DCC controller that understands how to drive accessory decoders (most controllers other than the very basic ones can do this).
