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

•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.
