Using this Renkus Heinz loudspeaker system is easy. First, find a stable and elevated place to set up the pair of speakers. Connect them to your audio source like a mixer or amplifier. Turn on your audio device and adjust the volume. Make sure the speakers are facing the area where you want the sound to reach. When it comes to maintenance, keep the speakers in a dry place to prevent damage from moisture. Regularly dust them off with a soft cloth. Avoid exposing them to extreme temperatures. If you notice any issues with the sound quality or the speakers themselves, stop using them and have a professional check them out.
