Using your Edifier Airpulse A80 speakers is easy. First, connect the power cable to a power source. Then, choose your input. You can use the RCA cables for analog sources, USB for digital, or optical for high - quality digital signals. Connect the speakers to each other using the provided speaker connecting cable. If you want to adjust the sound, use the on - board rotary controls on the rear of the speakers or the wireless remote. Place the speakers on the acoustic isolation pads to reduce vibrations. When not in use, turn off the speakers to save energy. For maintenance, keep the speakers clean by gently wiping them with a soft, dry cloth. Avoid exposing them to extreme temperatures or humidity. If you add a subwoofer, connect it to the subwoofer output for more bass.
