remote room to the A location with wire for
an infrared receiver and speakers or an amplifier

mend that you make a direct connection or use
an optional, external IR “blast connected to

are in doubt as to which IR Output jack to use
for the equipment in yo system, contact your
dealer or installer or th manufacturer’ support
site and ask whether the unit to be controlled

ultiroom Audio Connections
Depending on your system`s requirement and
distance from the A to the remote room, three
options are available for audio connection:
Option 1 (on A 355): Use high-quality
s
hielded audio interconnect phono cable from
the A location to the remote room. In the
remote room, connect the interconnect cable to
a stereo power amplifier T amplifier will be
connected to the room’ speakers At the A
plug the audio interconnect cables into the
Zone 2 Out Jacks
b
on the A rear p
Option 2 (on A 355): Place the amplifier
that will provide power to th remote l
speak in th same room as th A an con-
nect the Zone 2 Out j b on t rear pane
of the A t the au input of th remote r
amplifier Use the a spea wire t con
nec the o powe ampl t the r
spe H wire of at least 2.5 mm

is
recommended for long multiroom c
Option 3 (on A 255 and A 355): T
advantage of the A built-in seven-channel
amplifier it is possible to use two of the amplifi-
er channels to power speak in the remote
room. When using this option you will not be
able to use the fu 7.1-channel capabilities of
the A in th main l room, but you will
be able to add a listening room without
additional external power amplifiers. T use the
internal amplifiers to power a remote zone con
nect the speakers for the remote room location
to the Surround Bac Speak
Outputs
O
. Be u the remote room you
will need to configure the amplifiers for sur-
round operation by changing a setting in the
Multiroom menu, following the instructions
shown on page 18.
NO For all options you may connect an
optional IR sensor (Harman Kardon He in
the remote room to the A via an appropriate
cable Connect the sensor’ cable to the Zone 2
IR Inp

on the A a 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 speak
NO T A 355’ multiroom system is only
capable of distributing analog audio sources to
the remote zone. T when connecting
your digital audio equipment (e CD or D
players) as described on page 18 mak sure to
use both analog and digital audio connections
to ensure that the d will be av to
the multiroom system.
A-BUS Installation Connections
(A 3 only
T A is among the very few receivers avail-
able today that offers buil A-BUS Re
®
operation. When used with an optional A-BUS
k or con module, y have all the
benefits of remote zone oper without the
n
eed for an external power amplifie
T use th A w an approved A-BUS prod-
uct, simply connect the k or module that is
in the remote room to the A using standard
“Category 5” wiring that is properly rated for
the inwall use specific to the installation.
T
erminate the wiring at the receiv end to a
standard RJ-45 jack in compliance w the
instructions furnished with the A-BUS module
Y may connect a single A-BUS module to the
A 355 with n further equipment ne If
you wish to connect more than one A-BUS
module an optional, external A-BUS hub may be
used to provide that capa
No further installation or ad is needed,
as the A-BU connector on the A routes the
signals in and out of the k to their proper
destination for power signal source and control.
T output fe to the A-BUS jack is determined
by the A multiroom system, and the me
may be used as i

mended for devices that have no power switch
or a mechanical power swi that may be left in

NO Many audio a video products go into
Standby mode when they are use with
switched outlets and cannot be fully turned on
using the outlet alone without a remote control
command.
T A dr significantly m current than
other household devices such as compute that
use removable power cords F that reason, it is
important that only the cord supplie with the
A 355 (AVR 255 has a fixed power cord) or a
direct replacement of identical capacity be used.
Once the power cord is connected, you are
almost ready to enjoy the A 255/A 355’
incredible power and fidelity!
