Using this Movek myMix personal monitor mixer is easy. First, connect it to your audio system as you would with a regular mixer. Since it doesn't have a power supply, you'll need to use PoE to power it. Just connect it to a PoE - enabled device or switch. When using, make sure the audio sources are properly connected to avoid audio glitches. As for maintenance, keep it in a clean and dry place. Wipe it gently with a soft cloth if it gets dirty. Don't expose it to extreme temperatures or moisture as it may damage the internal components.
