mfx High-Efficiency Electronic Circuit with a Sound Effects Generator.

For diesel locomotives. This kit is for converting Märklin H0 locomotives with built-in 6090, 60901, 60903, or 60904 high-efficiency propulsion to the new version with a feedback feature and sound effects. The existing high-efficiency motor is retained, the locomotive decoder is replaced, and a speaker is also installed. 12 typical diesel locomotive operating sound effects are pre-programmed and can be activated according to the table. The following special sound effects specific to the operation of the locomotive are present on this decoder:
F7 = high pitched horn tone.
F8 = low pitched horn tone.
F9 = auxiliary diesel with constant rpm.
F10 = sound of excess pressure safety valve letting off air.
F13 = sound of doors being closed.
F14 = startup of the motor.
F15 = oil pump.

Also available are controllable functions including direct control without acceleration/braking delay as well as 3 function outputs that can be assigned as desired, one of which changes over with the direction of travel. Circuit board dimensions 35 mm / 1-3/8" length x 15 mm / 9/16" width x 6 mm / 1/4" height. Speaker diameter 22 mm / 7/8", height 3 mm / 1/8".
