The LokSound 5 Fx is a special feature of the LokSound family: it has no output and is specially designed for use in control cars or drive heads, which require a sound but do not have a model drive themselves. By omitting the engine part, it can still offer all the sound features of the other LokSound 5 members on a size of only 21.5mm x 15.5mm.
LokSound 5 Fx decoders are offered with an 8-pole interface according to NEM652 or a 21MTC cutting point and always come with an 11 x 15 mm "sugar cube" loudspeaker and sound capsule kit.
