Using the Behringer EUROLIVE B15X is easy. First, connect your audio source. You can use a wired connection or pair your Bluetooth - enabled device like a smartphone or tablet. If you're using a wireless microphone, make sure it's compatible with the 'wireless - ready' feature. Adjust the settings on the 3 - channel digital mixer using the intuitive single - rotary control with an LCD display. You can also use the free iOS or Android app for remote control. When positioning the speaker, you can use the 35 - mm pole socket for stand mounting or tilt it on its side to use as a floor monitor. For maintenance, keep the speaker clean and dry. Avoid exposing it to extreme temperatures or humidity. If you're not using it for a long time, store it in a cool and dry place. And always follow the safety instructions provided in the user manual.
