You will need to delve into the 565 manual. Start by setting a "TYPE". Choose a type that most closely matches your setup from the manual.
This will give you sound and is a start point for your own bespoke setup.
Meridian is not plug and play, you have to role your sleeves up, but its worth it and it will sound great.

Good luck, Chris smile
