Please spend a few moments reading this sound guide as it may answer some questions you have and will help you achieve maximum satisfaction from this Protodrive sound project.
Working Brake Key
Our Protodrive sound projects are set up to use F2 as a working brake key. When reducing the speed of the loco F2 can be applied to slow the train down at a fast rate. The button can be held down to come to a stop quite quickly, or dabbed to slow the loco down faster that coasting, but smoother than slamming the brakes on – much like a real locomotive.
Volume Control
Digitrains’ sound project give you two ways of adjusting the sound volume, depending which you find easier to use is the best way! F27 will reduce the overall volume whilst F28 will increase it. When using the F-keys you must turn them off once at the desired level.
Zimo sound projects also use CV266 to adjust the volume, 64 being default. We recommend keeping below a value of 120 to prolong the life of the speaker and the decoder – this value is the maximum when using F28.
Speed Dependant Whistles
Whistles are controlled by F3 & F4. The faster you go, the long the sound.
Speed Related Flange Squeal
Our latest Protodrive sound projects also include speed related flange squeal. When above speed step 20 you will notice that the flange squeal changes. Flange squeal is controllable through F9 but will only play when moving and under 50 speed steps.
Function Handbrake
F11 acts as a functioning handbrake. The locomotive must be stationary to activate it. When engaging this function, instructions can be heard given from the driver to the fireman instructing them to apply the handbrake. The locomotive will not move with F11 active.
Speed Dependant Detonators
Another feature of our latest Protodrive sound projects is the use of speed related detonators. When engaging F14 you will hear a series of three minor explosions to inform the train crew that the train in front has broken down or had an accident. This are placed at a fixed distance between one another on the track so the faster you go, the closer together the detonations are.
Unfitted Freight Mode
When F18 is engaged, a guard to driver instruction will be heard, explaining what type of freight service is in transport. The top speed of the locomotive will also be reduced whilst F18 is active. F21 will pin the brakes on the wagons so as you drive, a brake squeal can be heard.
Air Pump
Selecting F23 will activate the air pump in this project. Once the function is turned on, the sound will start to play. By leaving the function switched on, the air pump will start to play at random intervals.
