14 INSTALLATION AND CONNECTIONS
Installation and Connections
NOTE: The AVR 300 will accept both standard
(composite) or S-Video signals. However, it will
not convert signals from one video format type
to the other.
System and Power Connections
The AVR 300 is designed for flexible use with
multiroom systems, external control compo-
nents 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 com-
mands. In this event, an optional remote sensor
may be used. Connect the output of the remote
sensor to the Remote Cont. In 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 c to the Remote In
jack on Harman Kardon or other compatible
equipment.
Multiroom IR Link
The remote room IR receiver should be connected
to the AVR 300 via standard coaxial cable. Plug
the IR connection cable into the Multiroom jack
¤ on the AVR 300’s rear panel.
If other Harman Kardon compatible source
equipment is part of the main room installation,
the Remote IR Output jack c on the rear
panel should be connected to IR IN jack on the
CD player or cassette deck. This will enable the
remote room location to control source equip-
ment functions in addition to the remote room
input and volume.
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 300
to the remote room, two options (A and B)
are available:
A. Use high-quality, shielded audio interconnect
cable from the AVR 300’s location to the
remote room. At the remote room, connect the
interconnect cable to a stereo power amplifier.
The amplifier will be connected to the room’s
speakers. No volume control is required, as the
AVR 300 and the remote IR link will provide
that function. At the AVR 300, plug the audio
interconnect cables into the Multi Out jacks
• on the AVR 300’s rear panel.
NOTE: The remote power amplifier must have
signal sensing capability or be left on constantly to
assure automatic operation at the remote room.
B. Place the amplifier that will provide power to
the remote location speakers in the same room
as the AVR 300, and connect the Multi Out
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 AWG14 is recom-
mended for long multiroom connections.
IMPORTANT NOTE: Any cables run inside walls
should be CL3/FT4 rated, or carry any other certi-
fication that is required by the NEC or state and
local building and electrical codes.To avoid inter-
ference, audio and speaker cables should not be
parallel to, or run in the same conduits or path
with, AC cables. If you have any questions about
multiroom wiring, consult your dealer, custom
installer or a licensed or low-voltage contractor.
External Audio Power Amplifier
Connections
If desired, optional external power audio power
amplifiers may be used with the AVR 300.
Connections to these amplifiers are made by
using audio interconnect cables connected to
both the Preamp Outputs ‚ on the rear
panel and the audio input jacks of the external
amplifiers.
External Audio Decoder Connection
To provide for ultimate flexibility, the AVR 300
may be used in conjunction with optional,
external decoders for digital audio systems
other than the AVR 300’s own built-in Dolby
Digital and DTS decoding system. If an external
decoder is used, connect the output jacks of the
decoder to the 6-Channel Direct inputs §,
making sure to match channels.
These jacks may also be used for connections to
devices such as DVD players or High Definition
Television (HDTV) sets or decoders that feature
built-in digital surround decoders. Although the
digital decoding system in the AVR 300 will typi-
cally provide audio performance that is superior
to other decoders, you may use these jacks to
provide an additional 6-channel input for connec-
tion to a DVD player or HDTV set with a built-in
decoder and discrete 6-channel analog outputs.
AC Power Connections
This unit is equipped with two accessory AC
outlets. 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 each outlet may
not exceed 150 watts.
The Switched fl outlet will receive power
only when the unit is on. This is recommended
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.
Finally, when all connections are complete, plug
the power cord into a nonswitched 120-volt AC
wall outlet.You’re almost ready to enjoy the
AVR 300!
