In addition to the output of simple signal tones, the LÜTZE TRANSPORTATION audio signal encoder also allows speech- or music-based warnings to be given. Audio files up to a total length of 15 minutes can be played.
The files that are to be played are selected via 6 digital wide range voltage inputs. Prioritisation of individual files is possible. Programming is realized using a free software.
The volume can be adjusted on the device using an integrated potentiometer. WAV and mp3 formats are supported. A version for wall mounting and one with an external loudspeaker are also available.
