Pair your smartphone or tablet via Bluetooth if using wireless streaming; insert a USB stick or SD card to play stored audio files.

Usage recommendations

For best sound and battery life, keep master volume at moderate levels and adjust tone controls to improve clarity. When using wireless microphones, power them on and check battery levels before a session; maintain line-of-sight between microphones and the speaker’s receiver where possible. Regularly back up media files and safely eject USB/SD cards after playback to avoid file corruption.
