INSTALLATION AND CONNECTIONS
System and Power Connections
The AVR 7500 is designed for flexible use with
multiroom systems, external control components
and power amplifiers.
Main Room Remote Control Extension
If the receiver is placed behind a solid or smoked
glass cabinet door, the obstruction may prevent
the remote sensor from receiving commands. In
this event, the remote sensor of any Harman
Kardon or other compatible device, not covered
by the door, or an optional remote sensor may
be used. Connect the
Remote IR Output
of
that device or the output of the remote sensor to
the
Remote IR Input
jack
.
If other components are also prevented from
receiving remote commands, only one sensor is
needed. Simply use this unit’s sensor or a remote
eye by running a connection from the
Remote
IR Output
jack
to the
Remote IR Input
jack on Harman Kardon or other compatible
equipment.
Multiroom IR Link
The key to remote room operation is to link the
remote room to the AVR 7500’s location with
wire for an infrared receiver and speakers or an
amplifier. The remote room IR receiver (this can be
an optional IR receiver or any other remotable
Harman Kardon device in the remote room with
IR sensor integrated) should be connected to the
AVR 7500 via standard coaxial cable. Connect the
Remote IR Output
of the device or of the
optional sensor with the
Multiroom IR Input
jack
on the AVR 7500’s rear panel.
If other Harman Kardon compatible source
equipment is part of the main room installation,
the
Remote IR Output
jack
on the rear
panel should be connected to the IR IN jack on
that source device. This will enable the remote
room location to control source equipment func-
tions.
NOTE:
All remotely controlled components must
be linked together in a “daisy chain”. Connect
the
IR OUT
jack of one unit to the
IR IN
of the
next to establish this chain.
Multiroom Audio Connections
Depending on the distance from the AVR 7500
to the remote room, two options are available
for audio connection:
Option 1:
Use high-quality, shielded audio
interconnect phono cable from the AVR 7500’s
location to the remote room. In the remote
room, connect the interconnect cable to a stereo
power amplifier. The amplifier will be connected
to the room’s speakers. At the AVR 7500, plug
the audio interconnect cables into the
Multiroom Output Jacks
on the AVR
7500’s rear panel.
Option 2:
Place the amplifier that will provide
power to the remote location speakers in the
same room as the AVR 7500, and connect the
Multiroom Output
jacks
on the rear panel
of the AVR to the audio input of the remote
room amplifier. Use the appropriate speaker wire
to connect the optional power amplifier to the
remote speakers. High-quality wire of at least
2.5 mm
2
is recommended for long multiroom
connections.
NOTE:
In both options, you may connect an
optional IR sensor in the remote room to the
AVR 7500 via an appropriate cable. Connect the
sensor’s cable to the
Multiroom IR Input
on the AVR 7500 and use the Zone II remote to
control the room volume. Alternatively, you may
install an optional volume control between the
output of the amplifiers and the speakers.
External Audio Power Amplifier
Connections
If desired, the AVR 7500 may be connected to
optional, external audio power amplifiers or
used with equalizers or speaker systems that
require connection between the preamp and
amplifier sections of a receiver.
To make these connections, remove the jumpers
that connect the
Preamp Out
jacks
and
Amplifier In
jacks
for the channels to be
used with external devices. Store the jumpers in
a safe place so that the AVR may be used in its
normal mode at a future date, if desired.
When an external amplifier is used, connect the
Preamp Out
jacks
to the inputs on the
amplifier. When an equalizer or speaker proces-
sor is used, connect the
Preamp Out
jacks
to the inputs of the processor, and connect the
outputs of the processor back to the
Amplifier
In
jacks
on the AVR. Note that when external
amplifiers or devices are used, volume is still
controlled by the AVR, although additional vol-
ume controls on the external device may affect
volume and output levels from the AVR.
AC Power Connections
This unit is equipped with two accessory AC out-
lets. They may be used to power accessory
devices, but they should not be used with high-
current draw equipment such as power ampli-
fiers. The total power draw to the
Unswitched
Outlet
must not exceed 100 watts, that to
the
Switched
Outlet
50 watts.
The
Switched
outlet will receive power only
when the unit is on completely. This is recom-
mended for devices that have no power switch
or 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 outlets, and cannot be fully turned on
using the outlet alone without a remote control
command.
The
Unswitched
outlet will receive power
as long as the unit is plugged into a powered AC
outlet and the
Main Power
Switch
1
is on.
Finally, when all connections are complete, plug
the power cord into a nonswitched 220-240-volt
AC wall outlet. You’re almost ready to enjoy the
AVR 7500!
