WavBox 

 
WavBox is a compact low powered audio player with a 

built in 20Watt class ‘D’ stereo amplifier that plays *.wav 
formatted audio files. 

 

WavBox operates as a standalone audio player, 

automatically booting and playing content from its on-board 
SD card as soon as power is applied or controlled via its 
serial interface. In addition, it can also be configured to be 
trigged via 1 of its 6 digital inputs using either buttons or 
PIR’s for example. 

 

Its compact size and low power consumption makes the WavBox ideal for integration into interactive 

displays and audio guides.
