751/752 (ex T478.1) "Bardotka" alias "Zamračená"


Sound project can manifest in a variety models differently. For MTB models for each scale we adapted sound project with individual settings.

Function assigning

  • F0 lights switch on/off
  • F1unassigned - reserved for advanced light
    MTB - red lights control
  • F2unassigned - reserved for advanced light
    MTB-H0 - spotlight control
  • F3 shunting mode
  • F4 short horn
  • F5
    • switch between sound versions
    • reduction acceleration/breaking time based on CV3 and CV4 to half
    • Slow start to model the sound of idle
  • F6 engine coasting
  • F7 long horn
  • F8 engine on/off
  • F9 cabin light on/off - only MTB H0 project
  • F10 coupling sound
  • F10 switch between sound versions
  • F11 sandblasting

Sounds for F4, F5, F7 and F11 is possible to play when the engine is off.

F3 - turn shunting mode reduces max. speed in half. This will soften the range of speed control locomotives during shunting. At the same time, the reduced acceleration/breaking time based on CV3 and CV4 is reduced to quarter, which will accelerate the model shift reaction.

F5 - switch between sound version is available when model is stopped and sound can be switched on/off. Other functionality is available pressing F5 on/off. Functionality is aggregated and switching sound version can be moved to another funkcion key by changing CV value. This functionality is available from decoder version 33.0 and above.

F6 - engine coasting to max. RPM is independent from throttle. This function allow have max. RPM also for standing loco or during slow drive. Usage depending on F8 switched on. Target level, to which have to be raised speed affects CV375. For this project, the max. value is 6. Works for firmware version 32 and above.

Function assigning and change of CV's value is possible.
