Digital Optical 3 Input:

Connect the opti-

cal digital output of an audio or video product to
this jack. When the input is not in use, be certain
to keep the plastic cap installed to avoid dust
contamination that might degrade future
performance.

(

Input/Output Status Indicator:

These

LED indicators will normally light green to show
that the front panel

Video 4 A/V

jacks or

the

Coaxial 3 Digital

jacks are operating as

inputs. When either of these jacks has been con-
figured for use as an output, the indicator will
turn red to show that the jack may be used for
recording. (See page 20 for more information on
configuring the front panel jacks as outputs,
rather than inputs.)

Digital Coax 3 Jack:

This jack is normally

used for connection to the output of portable
audio devices, video game consoles or other
products that have a coax digital jack. It may
also be configured as an output jack, to feed a
digital signal to a CD-R, MiniDisc or other digi-
tal recording device. (See page 20 for informa-
tion on configuring the Digital Coax 3 Jack as
an output.)

Video 4 Input Jacks:

These audio/video

jacks may be used for temporary connection to
video games or portable audio/video products
such as camcorders and portable audio players.
