To prevent possible damage to your speakers
and other components in your audio system, it is
important that ALL components, including the
HD 990 and your receiver or preamp and ampli-
fiers, are turned off and unplugged from their AC
power source when installing any new compo-
nent.
Connecting the HD 990 to your audio system is
simple. Using standard RCA-to-RCA interconnect
cords or balanced XLR-cables, connect the left
and right Audio Output jacks 1 on the rear
panel to the CD input jacks on your receiver, sur-
round processor or preamplifier.
If your system includes an optional external
digital-to-analog converter, or if you are using a
receiver or other processor that has the capabili-
ty to decode PCM digital input signals, connect
the Coaxial or Optical Digital Output jack
0 to the Coaxial or Optical Digital input on the
decoder. Make certain to use a coaxial-style
interconnect cable, as standard audio cables will
not perform as well.
If you use the matching Harman Kardon amplifi-
er HK 990, you may connect it to the HD 990
with the special HRS-Link cable, which trans-
mits both audio and clock-synchronization sig-
nals. This very advanced connection rewards you
with ultimate sound quality. Simply connect the
HRS-Link Output 6 on the HD 990 to the HRS-
Link Input on the HK 990.
If you have additional external audio sources,
you might want to connect their coaxial or opti-
cal digital output to the Coaxial or Optical
Digital Inputs 5 on the rear panel of the CD
player. This will enable you to use the audiophile
high-grade digital-to-analog convertors and pro-
cessing power in the HD 990 rather than the
(older and less-powerful) convertors of your
external source.
Note that in order to hear the sound from the
external source when connected like this, the
input of your amplifier or receiver should be the
one to which the HD 990 is connected.
Install two AA batteries by turning the remote
over so that you are holding the bottom side up.
Press lightly on the embossed arrow on the
cover and gently slide the cover towards you in
the direction of the arrow. Insert the batteries
inside the compartment, being careful to follow
the + and – polarity indications at the bottom of
the compartment. Replace the cover by placing it
on the remote and sliding it back towards the
top of the remote.
NOTE: When replacing batteries, always replace
both at the same time. When the unit will not be
used for an extended period of time, it is also a
good idea to remove the batteries so that the
potential for corrosion or damage is avoided.
If the HD 990 is installed behind a cabinet or
other obstruction that may block the path
between the front-panel Remote Sensor and
the location of the remote, an optional external
IR sensor may be used. Connect the sensor to
the Remote IR-In Jack 2 on the rear panel.
This jack may also be connected to the IR-
Output jack of another compatible Harman
Kardon component or a compatible IR-system-
remote product.
You may also use the IR Sensor in the HD 990 to
send commands to other compatible remote
controlled products. Connect the Remote IR-
Out jack 3 to the input of the other product
or system.
Connect the power to a nonswitched AC wall
outlet or to the accessory outlet on the rear of
another audio device in your system and you are
ready to go!
NOTE: When using the accessory outlet on
another product to power the HD 990 make cer-
tain that it has the compatibility to power a
device that draws at least 20 watts of current in
addition to being able to handle the require-
ments of the other devices that may be plugged
into the accessory outlets. If you use a
“switched” outlet, it is important to remember
that the host product must be turned on in order
for the HD 990 to operate.
