REAR-PANEL CONNECTIONS 9
REAR-PANEL CONNECTIONS
positive, or “+,” terminal that should be connected to
the red (+) terminal on the Surround Left speaker with
older color-coding, while the gray terminal should be
connected to the red (+) terminal on the Surround
Right speaker with the older color-coding. Connect the
black (–) terminal on the AVR to the matching black
negative (–) terminals for each surround speaker. (See
page 15 for more information on speaker polarity.)
¶ Front Speaker Outputs: Connect these outputs
to the matching + or – terminals on your left and right
speakers. When making speaker connections always
make certain to maintain correct polarity by connecting
the color-coded (white for front left and red for front
right) (+) terminals on the AVR 325 to the red (+)
terminals on the speakers and the black (–) terminals
on the AVR 325 to the black (–) terminals on the
speakers. See page 15 for more information on
speaker polarity.
• Fan Vents: These ventilation holes are the output
of the AVR 325’s airflow system. To ensure proper
operation of the unit and to avoid possible damage to
delicate surfaces, make certain that these holes are
not blocked and that there is at least three inches of
open space between the vent holes and any wooden
or fabric surface.
ª Center Speaker Outputs: Connect these outputs
to the matching + and – terminals on your center
channel speaker. In conformance with the new CEA
color-code specification, the green terminal is the
positive, or “+,” terminal that should be connected to
the red (+) terminal on speakers with the older color-
coding. Connect the black (–) terminal on the AVR to
the black (–) terminal on your speaker. (See page 15
for more information on speaker polarity.)
‚ Surround Back/Multiroom Speaker Outputs:
These speaker terminals are normally used to power
the surround back left/surround back right speakers
in a 7.1 channel system. However, they may also be
used to power the speakers in a second zone, which
will receive the output selected for a multiroom system.
To change the output fed to these terminals from
the default of the Surround Back speakers to the
Multiroom Output, you must change a setting in the
Advanced Menu of the OSD system. See page 32 for
more information on configuring this speaker output. In
normal surround system use, the brown and black ter-
minals are the surround back left channel positive (+)
and negative (–) connections and the tan and black
terminals are the surround back right positive (+) and
negative (–) terminals. For multiroom use, connect the
brown and black SBL terminals to the red and black
connections on the left remote zone speaker and con-
nect the tan and black SBR terminals to the red and
black terminals on the right remote zone speaker.
⁄ Switched AC Accessory Outlet: These outlets
may be used to power any device you wish to have
turned on when the AVR 325 is turned on with the
System Power Control Button 2.
¤ Unswitched AC Accessory Outlet: This outlet
may be used to power any AC device. The power will
remain on at this outlet regardless of whether the
AVR 325 is on or off.
NOTE: The total power consumption of all devices
connected to the accessory outlets should not exceed
100 watts.
‹ AC Power Cord Jack: Connect the AC power
cord to this jack when the installation is complete.
To ensure safe operation, use only the power cord
supplied with the unit. If a replacement is required it
must be of the same type and capacity.
› Video Monitor Outputs: Connect these jacks to
the composite or S-Video input of a TV monitor or
video projector to view the on-screen menus and the
output of any standard video source selected by the
receiver’s video switcher.
fi DVD Video Inputs: Connect the composite or S-
Video outputs of a DVD player or other video source
to these jacks.
fl Video 1 Video Inputs: Connect the composite or
S-Video PLAY/OUT jacks of a VCR or other video
source to these jacks.
‡ Video 1 Video Outputs: Connect the composite
or S-Video REC/IN jacks of a VCR or other video
recording device such as a DVD recorder or PVR to
these jacks.
° Video 2 Video Inputs: Connect the composite or
S-Video PLAY/OUT jacks of a VCR or other video
source to these jacks.
· Video 2 Video Outputs: Connect the composite
or S-Video REC/IN jacks of a VCR or other video
recording device such as a DVD recorder or PVR to
these jacks.
a Video 3 Video Inputs: Connect the composite or
S-Video PLAY/OUT jacks of a VCR or other video
source to these jacks.
b Component Video Monitor Outputs: Connect
these outputs to the component video inputs of a
video projector or monitor. When a source connected
to one of the
Component Video Inputs cd is
selected, the signal will be sent to these jacks.
c DVD Component Video Inputs: Connect the
Y/Pr/Pb component video outputs of a DVD player to
these jacks.
d Video 2 Component Video Inputs: Connect the
Y/Pr/Pb component video outputs of an HDTV set-top
converter, satellite receiver or other video source
device with component video outputs to these jacks.
e RS-232 Port: This jack is used to enable the
AVR 325 to be controlled by an external computer
or programmable remote system that uses RS-232
commands. Due to the complexity of RS-232 con-
nections, we recommend that they be made by a
trained and qualified custom installer. See page 16
for more information on the RS-232 control port.
f Multiroom IR Input: Connect the output of an IR
sensor in a remote room to this jack to operate the
AVR 325’s multiroom control system.
g Remote IR Input: If the AVR 325’s front-panel
IR sensor is blocked due to cabinet doors or other
obstructions, an external IR sensor may be used.
Connect the output of the sensor to this jack.
h Remote IR Output: This connection permits the
IR sensor in the receiver to serve other remote con-
trolled devices. Connect this jack to the “IR IN” jack on
Harman Kardon (or other compatible) equipment.
i Coaxial Digital Audio Output: Connect this jack
to the coaxial digital input of a CD-R/RW, MiniDisc or
other digital recorder.
j Multiroom Audio Outputs: Connect these jacks
to the optional external audio power amplifier and
video distribution system that delivers the source
selected for multizone distribution.
k Optical Digital Audio Output: Connect this jack
to the optical digital input connector on a CD-R/RW,
MiniDisc or other digital recorder.
CD Audio Inputs: Connect these jacks to the
analog audio output of a compact disc player or CD
changer.
DVD Audio Inputs: Connect the left/right analog
outputs of a DVD player or other audio source to
these jacks.
Optical Digital Audio Inputs: Connect the optical
digital output from a DVD player, HDTV receiver, the
S/P-DIF output of a compatible computer sound card
playing MP3 files or streams, LD player or CD
player
to these jacks. The signal may be a Dolby Digital signal,
a DTS signal or a standard PCM digital source.
Tape Inputs: Connect these jacks to the PLAY/OUT
jacks of an audio recorder.
Tape Outputs: Connect these jacks to the
RECORD/INPUT jacks of an audio recorder.
