or new configuration to the amplifiers internal 

memory. To record a message please make 

sure your file is in an MP3 format. Connect 

the amplifier to the USB port of your

File on the amplifiers MP3 Player and drag 

your saved MP3 file from computer to the 

MP3 player on the amplifier. This will then 

become the new recording when the alert 

input contacts are activated

This will cause the MP3 player to the play the 

message from the internal memory by simply 

shorting the two contacts together. This can 

be done via a control board, timer unit or a 

simple switch connected to the amplifier.

priority – it will mute all the other inputs 

to their minimum levels and play the pre-

recorded message. (See dipswitch settings at 

the beginning of this manual.)
