Basic Installation Guidelines
As a reminder for any installation:
• Don’t pick a locomotive whose stall current exceeds the rating of the
decoder. Always test the stall current of your locomotive before your
installation.
• Do pick a smooth running locomotive that runs well on straight DC
power. A smooth running mechanism is vital for good throttle control
and enhances the realism of the sound. Dirty, worn out or binding
mechanisms not only overload the decoder, but also will have trouble
starting smoothly and will destroy the illusion created by the Auto-
Exhaust feature if they barely lurch along at half throttle.
• Do start with an engine that is ‘sound-ready’ if possible, such as an
engine with predrilled speaker holes, or a diesel with a roomy ‘B’ unit.
• Don’t pick a noisy engine, or one, which experiences some arcing or
sparking when in operation. The best sound will come from locomotives
powered with can motors. Older, open-frame motors may produce an
offensive, interference sound.
• Provide ventilation for the decoder; try to mount the decoder so that
some airflow can occur.
• Mount the decoder away from other heat sources, such as the motor or
lamps to reduce the possibility of overheating.
• If you can, mount the decoder so that the ‘flat’ side is against a metal
chassis or weight. This will further help to dissipate heat.
• Always provide a proper baffle (enclosure) for the speaker and choose
the largest speaker possible.
