ESU Loksound 58210 58210 LokSound 5 Fx, DCC/MM/SX/M4 Blank Decoder 8 Pin, NEM652 with 11mmx15mm Speaker. Although the LokSound 5 Fx itself does not have an engine output, it still "simulates" one. This is used for synchronization with the motor car, where ideally a "full-fledged" LokSound 5 decoder performs its service.
