running at slow speeds, the sound system will be in simple mode. At faster speeds, the system
will change to compound. A function is provided (dccF2 - pin2) to manually control this as well as
the LocoMatic™ Controller's Coupler Rear buttons (Alt-Cplr) as a push on, push off (or leave
automatically turn off via faster speed operation). The engine must come to a slower speed
before re-enabling the simple mode of exhaust operation.
LIGHTING EFFECTS: Automatic headlight, backup, marker, cab lighting with motor polarity.
Override control is available to DC operators via the LocoMatic™ Controller (#755). After any
manual lighting operation is selected, automatic lighting may be accomplished via the Alt-Bell
buttons. Depressing this set returns the lighting back to automatic operation.
SPEAKER MOUNTING: The main speaker (connected to SPKR on the main board) should be
mounted so that the sound can actually "get out" of the locomotive. A hole in the floor of the
tender is acceptable but the front of the coal bunker or even through a simulated coal load may
be a better choice as the sound can exit forward or upward rather than down toward the track. In
some cases, particularly in the larger gauges, mounting a speaker inside the front of the boiler
with a open stack can enhance the sound. Enclosing the speaker in a chamber will also enhance
sound reproduction. A very simple enclosure can be made with a tube. It is usually best to seal
the end of the tube, so there are no air passages to the rear of the speaker, thus creating a sound
chamber. By carefully sealing all openings it may be possible to use the entire tender body shell
as a sound chamber thereby not requiring a tube type enclosure. A simple wall behind the
speaker may be all that is possible or perhaps all that is needed.
The other two speakers should be mounted in the main boiler if possible. Speaker 1 (connected
to SPKR1 on the Engine board), from the Engine board, contains the whistle and front exhaust
sounds. Speaker 2 (connected to SPKR2 on the Engine board) contains the Bell and rear
exhaust sounds (in compound engines). Other sounds are also produced from all of the
speakers. Since these are mounted in the boiler, round speakers are the best selection with
proper baffles. Do not mount the speakers without a proper baffle since that will produce an
inferior sound.

INDICATION
Speakers can be attached with double sided tape, with glue or with "hot melt". Enclosures can be
made with plastic, wood, card stock or even metal if so desired. Medicine bottles make excellent
sound chamber enclosures for round speaker types. Attachment with "hot melt" is advantageous
as the "hot melt" can be used as a gap filler when creating an enclosure.
Speaker enclosure is an art and experimentation is definitely in order for your installation so as to
gain the maximum benefit of the superb sound quality available in this sound system.
GENERAL OPERATING INFORMATION:
VOLUME ADJUSTMENTS: should be set as desired for your application. These volume controls
do not allow for the sound volume to go completely off, they merely give a range for the individual
volumes. Vol1 controls SPKR1, Vol2 - SPKR2, Vol3 - SPKR. Again, SPKR1 and SPKR2 are the
speakers connected to the Engine board. The main tender speaker is labeled SPKR on the main
board and is controlled by Vol3. Please remember that the amplifier can produce more power
than a small speaker can handle and that the sound will be louder if the speaker is properly
enclosed and baffled. If you are using batteries, the louder the volume the shorter the battery life.
TREBLE / BASS CONTROLS Each audio channel has it's independent Treble and Bass controls.
These are true Treble and Bass controls and not just tone type controls. If full boost is used, it
may be necessary to reduce the volume on that channel to prevent overdrive of the amplifier and
speaker. Again, the relationships are the same as the volume controls. Vol1 (Volume control 1) -
BASS1 (Bass control 1) - Trbl1 (Treble control 1) all control SPKR1. The others follow the same
nomenclature.
MISC: Another feature incorporated in this sound system is the ability to turn all sounds off,
leaving only the Whistle and Bell to operate. This can be done with the LocoMatic™ Controller by
using the ALT & F4 button and is a push on / push off function. Other operators can access this
with using function inputs.
