I/O Label Input/Output Description
1-8 Input MP3 Triggering inputs. When one of the inputs labeled 1-8 have a closed connection to the
GND terminal located in the top left corner of the terminal block, that numbered MP3 file
will be triggered and will play through the Audio Generator.
Example: When input 3 is triggered, the MP3 filed saved on the USB drive as 3.mp3 will be
played.
STOP Input The STOP input. When this input has a closed connection with the GND terminal located
in the top left corner of the terminal block, it will immediately stop any MP3 from playing
through the Audio Generator.
BGM Input The inputs labeled BGM and GND (right next to the BGM input) are where background
music from a device such as a computer or a radio can be fed into the Audio Generator.
This background music will play until a MP3 is triggered, at which time the background
music will fade out and the triggered MP3 will be broadcast. Once the triggered MP3 has
completed playing, the background music will continue to play.
8Ω Output 8Ω output to PA or amplifier system.
RCA cables are supplied for connection between these outputs and the PA or amplifier
system.
600Ω Output 600Ω output to PA or amplifier system.
