Harman Kardon AVI 250 - Multiroom Operation; Multiroom System Installation; Multiroom Wiring Notes; Multiroom Setup Procedure

ENGLISH
The AVI250 is unique among A/V ampli-
fiers in that it is equipped to operate as
the control center for a sophisticated
multiroom operation with accessories as
simple as a remote IR sensor or as
sophisticated as a specialized external
amplifier and a special version of the
world-famous AudioAccess wall mounted
keypad controls. Although some multi-
room installations will require the ser-
vices of a specially trained installer, it is
possible for the average do it yourself
hobbyist to install a simple remote room
system. For additional information on
using the AVI250 in multiroom installa-
tions we suggest that you contact your
dealer or custom installer.
Installation
The key to remote room operation is to
link the remote room to the AVI250’s
location with wire for an infrared receiv-
er and speakers or an amplifier.
TR Link
The remote room IR receiver should be
connected to the AVI250 via standard
coaxial cable. Plug the IR connection
cable into the mini jack inside the Multi
area in the middle of the unit's rear
panel.@
If other Harman Kardon compatible
source equipment is part of the main
room installation, the REMOTE
CONT. OUT jack 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 equipment functions as
well as the remote room input and
volume.
NOTE: All remotely controlled compo-
nents 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.
Audio Link
Depending on the distance from the AVI
250 to the remote room, two options are
available.
The preferred method is to run high
quality, shielded audio interconnect
cable from the AVI250’s location to the
remote room. At the remote room, con-
nect the interconnect cable to a stereo
power amplifier. The amplifier will be
connected to the room’s speakers. No vol-
ume control is required, as the AVI250
and the remote IR link will provide that
function. At the AVI250, plug the audio
interconnect cable into the MULTI OUT
jacks G at the top left corner of the AVI
250’s rear panel.
NOTE: The remote power amplifier must
have signal sensing capability or be left
on constantly to assure automatic opera-
tion at the remote room.
As an alternative, the amplifier may be
placed at the same location as the AVI
250, with a standard audio interconnect
between the two. Speaker wires should
then be run to the remote room. High
quality AVG-12 speaker wire is preferred.
IMPORTANT NOTE: Any cables run
inside walls should carry safety certifica-
tion that is required by the local building
and electrical codes. To avoid interfer-
ence, audio and speaker cables should
not be parallel to, or in the same
conduits with AC cables. If you have
any questions about multi-room wiring
consult your dealer, custom installer or
a licensed contractor or electrician.
