Connecting the AV Receiver About AV Connections • Before making any AV connections, read the manuals supplied with your other AV components. • Don't connect the power cord until you've completed and double-checked all AV connections. Optical Digital Jacks The AV receiver's optical digital jacks have shutter-type covers that open when an optical plug is inserted and close when it's removed. Push plugs in all the way. Caution: To prevent shutter damage, hold the optical plug straight when inserting and removing.

Use red plugs to connect rightchannel audio inputs and outputs (typically labeled "R"). Use white plugs to connect left-channel audio inputs and outputs (typically labeled "L").
