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”.

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