During the operation of automated guided vehicles (AGV) there often is a demand to
let the vehicles play notification sounds at certain positions throughout the track. For
this purpose the audio player HG G- 31500 was developed. Various interfaces make
system integration easy. An audio amplifier for direct connection of loudspeakers is
already integrated.
The audio player does not have internal speakers. External speakers and USB stor

The audio player is characterized in particular by its large number of inputs, which
can be used to control the selection and playback of audio files. The supply voltage
range of 10 – 30 V was also designed so that the player can be easily integrated into
a vehicle.

temperature range. If it is operated in a temperature range for which the USB
