| We now have a new sound system
utilizing a Phoenix Sound Systems "Big Sound " sound board
which stores sounds as 16 bit sound samples giving more fidelity and
realism. The new sound systems incorporate the following features:
Engine sound specific to particular locomotive:
F7 and GP7s with 1500 HP 567B engines
F9 and GP9s with 1750 HP 567C engines
Medium HP units with 645 engines such as GP38 or GP40s
High horsepower locomotives with turbo chargers like our GP60
locomotive line.
Other engine sounds availably by request.
Sound system characteristics:
At initial system turn on there is engine start up sound and
periodic air releases while locomotive is at idle. Engine sound
increases in volume as locomotive is notched up then fades so the gear
and turbo charger whine ( if turbocharged ) is more prominent when the
engine is coasting or slowing. Brake squeal is heard when engine speed
is reduced.
Bell and multi chime horns standard with optional single chime
available for F units or GP9 locomotives.
Automatic sound system ( as supplied with our powered locomotives)
senses motor voltage changes and notches the engine sound up or down
as appropriate. Also includes a volume control on the control box.
Manual version is supplied with a hand held control box
incorporating the following: potentiometer to increase engine speed,
horn button, bell switch, volume control, power switch. Also included
are cabling with plug and socket for disconnecting unit from
locomotive.
Both models come complete with amplifier, speaker, necessary wiring
components, complete instructions, drawings, and construction photos.
The photo shows all components except controls, mounted on speaker
enclosure but sound board and amplifier can be mounted separable if
desired. Also our choice of an 6" X 9" inch speaker was
dictated by locomotive space considerations. If you have more room a
second or larger speaker may be added. The larger the speaker, the
more powerful the sound. |
