Knowing and Installing Your Optical Digital I/O Card 4
7. Place the metal bracket of the Optical Digital I/O card into the unused bracket on the computer
casing.
8. Secure the card to the casing with a screw and replace the cover onto your system.
9. Plug the power cord back into the wall outlet and switch on the system.
Your Digital I/O
Module
Your Digital I/O Module has these jacks which allow you to attach other devices:
❑
SPDIF recording can be done only through the Optical Digital I/O card, where you connect the
Digital I/O Module to the Digital In/Out jack.
❑
There can be two simultaneous SPDIF Out connections: one through the coaxial connector, the
other through the optical connector. However, only one SPDIF In connection is possible at a time.
This means that you can connect to either the SPDIF In (RCA) jack or the SPDIF In (Optical)
jack but not both at the same time.
You can route signals from
SPDIF In to SPDIF Out through
the “SPDIF Bypass” feature
(under Digital I/O tabbed page of
the Device Controls window in
AudioHQ). This feature allows
you to share the SPDIF output
path through the Digital I/O
Module from the audio card OR
another SPDIF output device
(e.g., DeskTop Theater 5.1
speaker system), without the
hassle of plugging in and
removing the connection to the
single RCA input from either of
the two devices.
SPDIF In (RCA/Coaxial) jack
Connects to SPDIF-supported devices
such as a Digital Audio Tape (DAT)
machine or MiniDisc (MD) player that
have SPDIF RCA connectors.
SPDIF Out (RCA/Coaxial) jack
Connects to SPDIF-supported devices
such as a DAT, MD recorder or
speakers that have SPDIF RCA
connectors.
SPDIF In (Optical) jack
Connects to SPDIF-supported devices
that have SPDIF optical connectors.
SPDIF Out (Optical) jack
Connects to SPDIF-supported devices
such as MiniDisc (MD) recorder that
have SPDIF optical connectors.
