Using this Soundcraft Compact Stagebox is easy. First, connect it to your audio system using the CAT5 cable. Plug in the correct power supply that comes with it. When setting up your audio sources, connect them to the 32 inputs. You can then use the 8 line outputs and 8 AES outputs to send the audio to your desired destinations. As for maintenance, keep it in a dry and clean place. Make sure to check the connections regularly to avoid any loose connections. If you notice any issues, don't try to fix it yourself. Instead, contact the Soundcraft support team.
