Coaxial Input Connector (Digital Input)
This is the digital input connector for coaxial cable.
It cannot be used for input of analog audio signals (no sound
is produced).
Optical Input Connector (Digital Input)
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.
