Multiroom Operation

28

The AVI250 is unique among A/V
amplifiers 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
multiroom installations will require the
services 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
installations 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 receiver
and speakers or an amplifier.

IR 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 

area in the middle of the unit’s rear
panel.

œ

If other Harman Kardon compatible
source equipment is part of the main
room installation, the 

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
components must be linked together in a
daisy chain. Connect the 

jack of

one unit to the 

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, 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 AVI250
and the remote IR link will provide that
function. At the AVI250, plug the audio
interconnect cable into the 

jacks 

®

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
operation 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 AWG-12 speaker wire is preferred.

IMPORTANT NOTE: Any cables run
inside walls should carry safety
certification that is required by the local
building and electrical codes. To avoid
interference, 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.
