Using the Artesia EZA - MC1 is easy. First, connect your speakers to the appropriate outputs and your audio sources to the inputs. You can use the large volume knob to set the sound level precisely. For more detailed volume control, use the attenuation adjustment in 1 - decibel steps. When you need to record or take a break, just flip the mute switch. The mono switch is handy when you want to check for phase issues in your mix. As for maintenance, keep it in a clean and dry place. Avoid exposing it to extreme temperatures or humidity. If there's dust, use a soft, dry cloth to gently wipe it down.
