How to hook up BD Player using 7.1ch Audio Out

Hi again guys,

just wanted to ask this 'rather stupid question': What do you use to hook up a 7.1 ch BD player from the player's audio out to the AV receiver's 7.1 ch Audio in? Normal phono leads?

Any suggestions as what route to go please? Prospective player is the Denon DBP-2012UD to a Marantz SR8500.

Thank you guys.

Lawrence
