SD card/USB details
Loop Functions
1 = play one chosen track on loop (repeat). Note: in this mode, individual tracks cannot be selected.
F = play all tracks within the same folder on your SD card or USB drive in sequence on loop (repeat).
R = shuffle – plays all tracks randomly no loop (no repeat)
A= plays all tracks in sequence on loop (repeat)

Selecting and playing individual tracks from a USB or SD card.
Press and hold the PLAY/PAUSE button.
Use the forward/back buttons to select the required track.
Release the PLAY/PAUSE button.
Your selected track will now be used and paused and will play when the PLAY/PAUSE button is pressed again.
Useful tips for getting the most out of your playback facility during a live performance :
Record a track with no sound on it, say 30 seconds long. Call this track ‘001 – Silence’ and make sure it’s always the first track in your file. The reason to do this, is to allow you sufficient time when inserting your memory stick to allow you to enter the play/pause track cueing facility without accidentally playing a track. You can then select the track want to leave the player in PAUSE ready for the performance.
Add a few seconds (up to about 30 seconds) of no sound (quiet) to the end of all of your recorded tracks.
The player will automatically play the next track in sequence if you have multiple tracks, so adding this quiet section to your tracks allows you time to stop your player and cue your next track, to avoid the player going into an unwanted track installation

1. There should be no obstacles before the speaker cabinet. You had better put the speaker cabinet on a speaker stand.
2. Use professional devices to suspend or install the speaker cabinets to avoid hurt.
3. Use the high-quality cable to ensure the best tone.
4. Please match the right power and impedance of the power amplifier and speaker cabinet.
5. Do not point the microphone to the speaker cabinet to avoid feedback.
