Quantum Revolution
Design Objective
The design objective was to produce the best possible realistic digital sounds in a compact user-friendly downloadable format. Download capability means that the decoder’s internal software can be reloaded for all possible current and future applications. Currently there are over 150 sound file options and many more are in the works.

Sound File 
IDs Sound file IDs or P/Ns are identified by a 2 part 7-digit number.  The first four digits are the type number (diesel 1XXX-XXX, steam 3XXX-XXX, etc), and the remaining 3 digits are the sound set numbers. For example, a G scale F7 is 1008-291.  This minimizes supply problems associated with non-downloadable units and helps assure a continual supply of the Revolution, however you want it and with the guarantee you have the latest software.

To Give you the Best Sound!
To give you the best sound we’re giving you the best speakers and enclosures.  High performance speakers and enclosures fine tuned for your specific loco applications are included with your purchase!  The user can specify his loco and the dealers will provide the best speaker options.  We have a list of speaker options for most popular locomotives so the users can choose the correct speakers for their application.  The Revolution was designed for 8 ohm speakers so the user has many options and is not limited to difficult to find 100 and 32 ohm speakers that are specified by other sound decoders.

Flexible Design Philosophy
We have designed these sound decoders to give you many years of pleasure and operating enjoyment.  The Quantum products are intended to grow with you and can be continually updated to give you the latest developments in sound files and performance features.  We are at the dawn of a new era of locomotive sound systems and appreciate that you have decided to join us.  We will work hard to continually provide you with updates and improvements so that you will always have available “state of the art” technology.  Also, we highly value your inputs and are prepared to create custom software builds to give you that special sound or feature that you want.

Format Options
There are two board formats planned for the initial release.  The complete specifications are to follow.  

1) The First format to ship - Revolution-A - will be a replacement board format style that is in widespread use for popular diesels like the Atlas type chassis locomotives and many others. See below.  

2) The Second is the Universal Format - Revolution-U. See details below.  Size: Atlas Format 0.69” X 2.86”.

What’s the Revolution Got That’s New?
Improvements in Quantum Revolution as compared to the original OEM releases by BLI, Atlas, Walthers, Proto 2000, Inter Mountain, Stewart and other sound decoders.

  • Advanced Co-Processor technology.

  • Low power design that allows mounting of the board anywhere in the locomotive.

  • Higher audio output for clear and loud sounds.

  • Additional flash memory provides for more sounds.

  • Higher voltage operation, 25 volts peak.

  • Better motor performance under intermittent power.

  • Super smooth low and mid speed performance under RTC.

  • Steam versions of the board support a chuff CAM.

Lighting: 

  • 6 light outputs, all with 256 intensity levels.

  • Support for both LEDs and low voltage, low current incandescent lights, eliminating dropping resistors.

  • High voltage bulbs not supported.

New Lights supported: 

  • Rear Mars Light.

  • Rear Ditch Lights.

  • Firebox.

How to Determine Which Decoder to Order?
We prefer that you contact your dealer to verify you are making the right choice.

  1. Choose either the Atlas Revolution or the Generic Revolution depending on a steam or diesel application and the space you have available. The Atlas style is primarily for diesels but may be used for steam if the space dictates so. There is no cam input. The Revolution's design is suitable for almost all applications.

  2. Make sure to try to optimize the space you have for the speaker and baffles. If there is space for 2 speakers, that’s the best option.

Once you have determined the above then you can decide on the appropriate part # for the sounds you want.

Part number selections would be as follows:

Revolution-A for the Atlas format.
