Any folder, containing song files, can be assigned for Wallbox and/or AutoPlay selections. The folder name itself, is limited

to only two numeric digits 01 to 99. Each song filename, within the folder, starts with the first three numeric digits 001 to 255

and ends with the last four character extension type, such as ".MP3" or ".WAV".

The player supports two Media File format types

MP3

(MPEG-1 Layer 3)

WAV

(Waveform Audio Format)

The examples below show the file size differences between the formats

001-Rock around the clock.mp3

002-Rock around the clock.mp3

003-Rock around the clock.mp3

004-Rock around the clock.wav

To create the MP3 song files from your CD you would use a program to "Rip" the CD tracks to MP3. Windows Media

Player can be used but make sure, in the Options menu, that the Format is set for MP3 (not WMA). There are many other

rippers, such as one by www.poikosoft.com, that will automatically insert the track numbers and song names.

Another consideration is the bit rate. The bit rate is similar to the resolution of a photo, lower resolution will produce a fuzzy

image. For music, bit rates below 128Kbps may start to sound grainy. You can't tell much of a difference using the

maximum bit rate of 320Kbps other than larger file sizes. Many agree that the bit rate of 192Kbps is very close to CD quality

(as we recommend).
