Overview
Congratulaons on the purchase of
your Bachmann locomove with digital
sound installed. This state-of-the-art
Digital Sound Decoder incorporates
WOWSound Digital Sound Technology
and will provide true CD-Quality audio,
realisc operaonal performance, and
the benets of DCC (Digital Command
Control) technology.
This Quick Start Guide assumes that
you have some understanding of, or
experience with, other “prototype”
trains and TCS’ decoders. It covers the
dierences you may need to know
between these decoders and any you
may have previously used.
If you are new to WOWSound you
should start by vising the TCS website
at www.tcsdcc.com to review the
WOWSound comprehensive guide as
well as watching the video tutorials
provided.
For most DCC operaons of the
locomove (selecng new sounds,
adjusng volumes, remapping or
changing lighng eects, etc.), it’s
easiest to use Audio Assist® (accessed by
pressing funcon buon 8 four mes in
quick succession while you are operang
your locomove in DCC mode). From
there the decoder will take over, talk to
you, and explain how to perform the
various conguraon acons available.
Features
With WOWSound decoders you
know you are geng the real
sounds of locomoves carefully
recorded, preserved, and played back
without distoron or manipulaon.
WOWSound’s signature CD-Quality
audio provides modelers with the closest
experience to standing track side.

In addion to excellent audio
performance WOWSound decoders

(Uninterruptable Power Supply) for
uninterrupted operaon, even over
dirty track, and the exclusive Audio
Assist® for easy conguraon without
programming CVs.

Programming Your Locomotive:
Address Programming:
The default address of all DCC decoders
is 3, so you can start by placing the
locomove on the rails and selecng
address 3 on your command staon.
To change the address to another
number less than 126 (99 for some
Command Staons), place the
locomove on the programming track
and following your command staon
instrucons for programming CV 1 to
your chosen address below 126.
For addresses higher than 126, use your
command staon’s instrucons for “long
address” programming.
Bachmann E-Z Command®:
For Bachmann’s E-Z Command® system,
simply follow your command station
instructions for programming the address
(programming track not required).
Conguring with Audio Assist:
With your locomove addressed and
responding on the DCC mainline, press
funcon buon 8 four mes rapidly to
enter Audio Assist. Audio Assist will then
guide you through conguring a wide
array of features.
Resetting Your Locomotive:
To reset your locomotive to factory
default settings you can program CV8=2
or (while operating on DCC) through
Audio Assist.
From the Audio Assist Main Menu the
button presses, in order, for a full factory
reset are:
Button 4 Button 3 Button 2

Running Your New Train:
Your new locomove is pre-congured
with all of the sengs best suited to
replicate the prototype. This means you
can place your engine on the track and
immediately start running with either
a DCC command staon or a 12v DC
power pack.
DC Operation:
Using a standard DC power pack
supporng up to 24v, your WOWSound-
equipped locomove will come to life
as soon as you place it on the track and
ramp up the power to 7.5v and above.
In DC operaon the sound and light
operaons will automacally operate
based on the direcon of travel and the
amount of power applied at the throle.
DCC Operation:
With your locomove address selected,
you can begin moving the locomove
with the throle control, and controlling
the light and sound funcons with the
funcon buons.
Buon mappings for triggering light,
sound, and motor responses will operate
a lile dierently depending on whether
the locomove prototype is Diesel,
Steam, or Electric.
