INSTALLATION AND CONNECTIONS
Option 2: Connect the Multiroom Audio Outputs
ø on the DPR 2005 to the inputs of an optional
stereo power amplifier. Run high-quality speaker wire
from the amplifier to the speakers in the remote room.
Option 3: Taking advantage of the AVR 7300’s built-
in seven-channel amplifier, it is possible to use two of
the amplifier channels to power speakers in the remote
room. When using this option you will not be able to
use the full 7.1-channel capabilities of the AVR 730 0
in the main listening room, but you will be able to
add another listening room without external power
amplifiers. To use the internal amplifiers to power a
remote zone, connect the speakers for the remote
room location to the Surround Back/Multiroom
Speaker Outputs ç. Before using the remote room
you will need to configure the amplifiers for surround
operation by changing a setting (following the instruc-
tions shown on page 39) in the MULTI-ROOM
SETUP menu.
NOTE: For all options, you may connect an optional IR
sensor in the remote room to the AVR 730 0 via an
appropriate cable. Connect the sensor’s cable to the
Multiroom IR Input UD on the AVR 730 0 and
use the Zone II remote to control the room volume.
Alter-natively, you may install an optional volume con-
trol between the output of the amplifiers and the
speakers.
Multiroom Video Connections
The AVR 7 300’s multiroom system is designed to
send both video and audio signals to a remote room
location. This may be the same source that is in use
in the main room, or you may select a separate input
source through the Multiroom menus or remote, as
explained on page xx.
The only additional connection required to add video
capabilities to your multiroom system is to connect the
Multiroom Video Outputs [square O] either directly to
the video display in the remote room or to any option-
al video distribution amplifiers that may be required
when the length of the connection cable is such that
additional amplification is required.
The following items may be of additional assistance
when using video as part of a multiroom system with
the AVR 7300 :
• When connecting the AVR 73 00 to a “digital ready”,
“HDTV compatible” or High Definition display, which is
any device capable of accepting an input signal of
480P or higher, you are able to take advantage of
the unit’s advanced video processing circuitry con-
verts all incoming video signals, regardless of the way
they are connected to the AVR. Since the AVR 73 00
is also among the very few products that display the
on-screen menus with up-converted video, the con-
nection from the AVR 7300 to the display need only
be one set of Y/Pr/Pb component video cables.
• Component video sources may not be routed through
the multi-room system. When using a component video
device, you should also make a composite or S-Video
connection to permit use of the multiroom system.
• As with all cable installations, when running any wiring
inside a wall be certain that the cable carries the prop-
er NEC rating for the application. The use of improper-
ly rated cables may present a safety hazard. Consult
a qualified installer or licensed electrician should you
have any questions about the use of in-wall cables
for video or audio.
A-BUS
®
Installation Connections
The AVR 7 300 is among the very few receivers avail-
able today that offer built-in A-BUS Ready operation.
When used with an optional A-BUS keypad or control
module, you have all the benefits of remote zone
operation without the need for an external power
amplifier.
To use the AVR 7 300 with an approved A-BUS prod-
uct, simply connect the keypad or module that is in
the remote room to the AVR 7300 using standard
Category 5 wiring that is properly rated for the in-wall
use specific to the installation. Terminate the wiring
at the receiver end to a standard RJ-45 connector in
compliance with the instructions furnished with the
A-BUS module.
No further installation or adjustment is needed, as the
A-BUS jacks on the AVR 7300 routes the signals in
and out of the keypad to their proper destination for
power, signal source and control. The output fed to
the A-BUS jack is determined by the AVR 7300’s mul-
tiroom system and menus.
RS-232 Connections
The AVR 7 300 is equipped with an RS-232 Port S
that may be used for two purposes. When the port is
connected to a compatible, optional, external computer,
keypad or control system the AVR 7300 is capable of
bi-directional communications that enable the external
system to control the AVR, and for the AVR to report
status and handshake data back to the controller. Use
of the RS-232 port for this type of control requires
specific technical knowledge, and we recommend that
any connection and programming for control be made
by a trained installer or technician familiar with the
equipment being used.
The RS-232 port may also be used as an access
point through which the AVR 7300’s operating system
and surround mode memories may be updated via
connection to a compatible computer. At the time
that an upgrade is available, instructions for making the
connection and installing the upgrade will be
available through the Product Support area of the
Harman Kardon Web site at harmankardon.com.
The physical connection to the AVR 7 300’s RS-232
port is a standard D-SUB 9 connection but to assure
compatible and proper operation, specific software
commands and pin wiring schemes may be required.
Trigger Jack Connection
The AVR 7 300 is equipped with a low voltage trigger
jack that may be used to activate optional, external
power amplifiers, screen motors, motorized blinds or
other compatible products that may be part of a home
theater installation. Once the connections are made,
operation is seamless in that the low voltage control
signal is sent to the screen, blinds or other device
when the AVR 730 0 is turned on, and it is turned off
along with the AVR. Due to the complexity of inter-
facing with power-controlled devices, we strong-
ly recommend that the installation be done by a
qualified installer.
The AVR 7 300’s trigger jack is a 3.5mm mono mini-plug
that delivers a 6 volt DC signal to the center pin ("tip") of
the plug ("+ ") with the outer shaft (‘ring") of the plug as
the negative ("-") or ground connection. After checking for
polarity, voltage and current draw compatibility between
the AVR and the product to be controlled, simply connect
the mini plug to the Trigger Jack [square A] on one end
and to the device to be controlled on the other. No further
programming is required.
The Switched AC Accessory Outlet d is powered
only when the unit is on. This is recommended for
devices that have a mechanical power switch that may
be left in the “ON” position.
NOTE: Many audio and video products go into a
Standby mode when they are used with switched out-
lets. This type of product may not operate properly
when used with the switched outlet.
The Unswitched AC Accessory Outlet c is
powered as long as the DPR is plugged into a
powered AC outlet.
The AVR 7 300 features a removable power cord
that allows wires to be run in advance to a complex
installation so that the unit itself need not be installed
until it is ready for connection. When all needed
connections have been made, connect the AC
Power cord to the AC Power Cord Jack b.
The AVR 7 300 draws significantly more current than
other household devices, such as computers, that use
removable power cords. For that reason, it is important
that only the cord supplied with the unit (or a direct
replacement of identical capacity) be used.
Once the power cord is connected, you are almost
ready to enjoy the AVR 7300’s incredible power
and fidelity!
