Triggered Sounds and Effects
The PB17 board has five trigger inputs. 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 6 and 12 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.
Radio Defect (Hotbox) Detector:
Plays a detector radio announcement
randomly selected from a list. Can be triggered or set to play
automatically.
Steam Only
Water Fill:
In programmed mode the sound plays 10 seconds after trigger if the
loco is stopped; in manual mode the sound plays when triggered.
Coal Loading:
In programmed mode the sound plays 10 seconds after trigger if
the loco is stopped; in manual mode the sound plays when triggered.
Mallet Mode:
Plays a second set of chuffs, moving in and out of phase with the
main chuff.
Second Chuff Trigger:
Plays a second set of chuffs independent of the main
chuff trigger.
