Triggered Sounds and Effects
The P5 board has two trigger inputs, normally assigned to speed. The
Auxiliary Input Board [P5T] allows you to trigger additional sounds
using reed switches or outputs from remote control receivers. The
following section describes sounds which may be assigned to triggers or
DCC functions. Of course, any sound can be assigned to a trigger. See
the tables on pages 12 and 22 for factory default trigger and DCC
Function assignments.
All Systems
Tunnel Fade:
This trigger causes the volume to fade down to a lower
setting. When the input is triggered again, the volume will come
back to the prefade setting.
Doppler:
In diesel, when you trigger this input, the next time the
crossing horn plays it will go thorough the pitch shift that you hear
as a train is speeding toward and then away from you. Doppler is
speed sensitive. In steam, triggering this effect will cause the pitch
of the chuff to shift as the engine approaches and a second
triggering will cause the pitch to shift back to normal.
Working/Drifting:
An effect that makes the locomotive sound like it is
struggling with a heavy train or coasting into a station.
Diesel Only
Dynamic Brake:
A triggered only sound. It is almost a tone which
results from using diesel drive motors as generators.
Rev Up/Down:
Causes the prime mover sound to go to the next/previous
rev. The sound will return to the corresponding rev based upon
speed changes.
Steam Only
Water Fill:
Plays 10 seconds after trigger unless set to manual.
Coal Loading:
Plays 10 seconds after trigger unless set to manual.
Mallet Mode:
Plays a second set of chuffs, moving in and out of phase
with the main chuff.
Second Chuff Trigger:
Plays chuffs independently of the main chuff
trigger.
