This is the digital input connector for coaxial cable.

 

It cannot be used for input of analog audio signals (no sound 
is produced).

 

This is the digital input connector for optic-fiber cable. Use 
commercially available optical cable for audio equipment to 
make the connection.

 

Optical-connector Protective Cap 

• After removing the protective cap, put in a safe place so 

that it doesn’t get lost.

• When not using the optical connector, attach the cap to 

keep the connector safe.

• When using the optical connector, be sure that the cap 

you removed is placed out of the reach of children. If a 
child has accidentally swallowed a cap, see a doctor 
immediately.

These are conduits
