Installing Mp3 Files Into Trigger Folders; Mp3 File Format - Redback A 1730 Operating Manual

Included on the micro SD card is a folder labelled #LIBRARY# (shown in figure 5) which includes a collection of sample
tones and messages which can be used for the trigger MP3's.

5.1 Installing MP3 files into trigger folders

To open a trigger folder simply double click on the relevant folder, such as our example of the trig2 folder shown in figure
6. Inside the folder will be a default MP3 file, named in this case "trigger2.mp3". This is the audio file that is played when
trigger 2 is activated. Delete this file and replace it with an MP3 file you want to play when you activate trigger2. This MP3
could be a file from the #library# folder or an MP3 of your own choosing.
The MP3 file name is not important only that there is a legitimate MP3 file in the trig2 folder (WAV, OGG or other formats
do not work).
Repeat this process for the required triggers.
Note: More than one MP3 file can be placed in the trigger folders. These will be played consecutively while the trigger is
activated.

5.2 MP3 file format

The audio files used must be in MP3 format, they cannot be WAV, OGG or other formats. The minimum recommended
MP3 format is 128kbps, 44.1kHz, 32bit, VBR or CBR, Stereo (even better as mono).
NOTE: the MP3 files used cannot be "Read only". To check this, right click on the MP3 file and scroll down and select
Properties, you will get a popup window. Make sure the "Read Only" box has no tick in it.
