The most important component of the new LokSound V4.0 decoder is the noise module. We have therefore given the LokSound V4.0 a super-large 32 Mbit flash memory chip on which up to 276 seconds of original sounds can be stored. The LokSound V4.0 works with 8 polyphonic channels. This means that up to eight sounds can be routed simultaneously via the 16-bit mixer and the new low-noise D/A converter. This allows us to achieve a much better representation of the complex aggregates of the model because we can “bundle” several channels. You will notice the difference immediately! The noises are passed on to the loudspeaker by the new, digital “class D” audio amplifier at a volume that is up to 3 times higher than before. Here too, we left nothing as is and used speakers with 4 ohm impedance for t.
