Connecting AV Components

Before Making Any Connections

Read the manuals supplied with your AV components.

Don’t connect the power cord until you’ve completed and double-checked all audio and video connections.

Optical Digital Inputs

The TX-L55’s optical digital inputs 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.

RCA AV Connection Color Coding

RCA-type AV connections are usually color coded: red, white, and yellow. Use red plugs to connect right-chan- nel audio inputs and outputs (typically labeled “R”). Use white plugs to connect left-channel audio inputs and out- puts (typically labeled “L”). And use yellow plugs to connect composite video inputs and outputs.
