MULTIROOM OPERATION 49

Multiroom Operation

The AVR is fully equipped to operate as the con-

trol center for a complete multiroom system that

is capable of sending one source to a second

zone in the house while separate source is

listened to in the main room. In addition to

providing for control over the selection of the

remote source and its volume, the AVR offers a

comprehensive range of options for powering the

speakers in the second zone.

• Using the line-level Multiroom Audio

Outputs

, the selected source may be fed to

optional, external power amplifiers that may be

matched to the specifics of the installation.

• When the main room system is configured for

5.1 operation, the Surround Back Left/Right

amplifier channels may be used to power the

remote zone so that no additional amplifiers are

required.

• Using built-in A-BUS/

READY

technology,

optional A-BUS modules may be connected to

the AVR via a single Category Five wire, so that

remote zone speakers may be powered directly

from the module or keypad without the need for

additional power, IR sensor or volume control

wires to be run to the second zone.

In addition, the AVR includes a remote IR sensor

input so that remote control commands from the

Zone II remote included with the unit may be

transmitted to the unit, while standard IR

input/output jacks allow the remote zone’s

commands to be sent to compatible IR-controlled

source devices.

Installation

Although simple remote room systems may be

installed by the average do-it-yourself hobbyist,

the complexity of your multizone/multiroom

system involves running wires inside of walls

where the services of a specially trained installer

may be required. Regardless of who does the

work, please remember that local building codes

may govern in-wall electrical work, including

proper specification of any wiring used and the

way in which it is connected. You are responsible

for making certain that all Multiroom installation

work is done properly and in compliance with all

applicable codes and regulations.

For standard installations, follow the instructions

shown on page 16 and 18 for the connection of

speaker wire and IR remote wiring to the AVR.

For installations where the Surround Back

Left/Right amplifier channels are used to power

the remote zone, make certain that the system is

configured for that type of operation, as shown

on page 49.

For installations where A-BUS modules are used,

follow the instructions provided with the A-BUS

remote modules or keypads.

Additional information will also be made

available through the Harman Kardon

Web Site at

RS-232 Control

The AVR is rare among A/V receivers in that it

provides the capability for full remote control

from compatible computers or specialized remote

control systems. RS-232 programming requires

specialized programming knowledge and for that

reason we recommend that it only be done by

qualified installers.

NOTE: The RS-232 port on this product is

for use by authorized service personnel

ONLY.

For more information on using the RS-232 port

for remote control, visit the Harman Kardon Web

site at

www.harmankardon.com

or contact our customer service department.

Multiroom Setup

Once the audio and IR link connections have

been made, the AVR needs to be configured for

multiroom operation using the steps below. Press

the OSD button

to bring the MASTER

(Figure 7) to the screen. Press the

⁄

button

twice, until the on-screen ➞ cursor is

next to the

MULTI-ROOM line. Press the Set

button

to enter the MULTI-ROOM

menu (Figure 24).

Figure 24

When the MULTI-ROOM menu appears, the

on-screen ➞ cursor will be at the

MULTI-

ROOM

line. Since this line is used to turn the

system on and off, do not make an adjustment

here unless you wish to turn the system on at

this time. To turn the system on, press the

›

button

so that ONis highlighted. If you do

not wish to turn the system on at this time or to

proceed to the next step, press the

Button

once so that the ➞ on-screen cursor is next

to the

MULTI IN line.

At the

MULTI IN line, press the

‹

›

buttons

until the desired Audio/Video input to the

multi-room system appears in the highlighted

video. When the selection has been made, press

the

button

once so that the ➞ on-screen

cursor is next to the

MULTI VOL line.

At the

MULTI VOL line, press the

‹

›

buttons

or hold them pressed until the

desired volume level for the multi-room system is

entered. DO NOT use the regular volume control

knobs for this setting. When all settings for the

multiroom setup have been made, press the

buttons

once so that the on-screen ➞

cursor is next to the

BACK TO MASTER

line and press the Set button

. If you

have no other adjustments to make, press the

OSD button

to exit the menu system.

Surround Amplifier Channel Assignment

The AVR is equipped with seven full-power

amplifier channels to allow for complete

7.1-channel operation without the need for

additional external amplifiers. However, in some

installations you may wish to use the traditional

5.1-channel configuration for the main listening

room, which allows the surround back left/right

amplifier channels to be used to power speakers

placed in a remote zone location.

If you wish to use the Surround Back channel

amplifiers to power the remote zone, you must

change a setting in the

MULTIROOM

SETUP

menu. To make that change, first call

up the menu system by pressing the OSD

Button

to bring the MASTER MENU

(Figure 7) to the screen. Next, press the

Button

until the ➞ cursor is next to the

MULTI ROOM line. Press the Set Button

to enter the MULTIROOM SETUP

menu.

To change the setting so that the Surround Back

amplifiers are fed by the source selected through

the Multiroom system, press the

‹

›

Buttons

so that MULTI is highlighted in reverse

video and press the Set Button

Remember that once this setting is made you will

not be able to take advantage of any of the

6.1/7.1- channel decoding or processing modes,

and no Surround Back speakers must be selected

in the speaker setup procedure outlined earlier. In

addition the speakers used for the remote zone

must be connected to the Surround Back/

Multiroom Speaker Outputs

. The volume

for these speakers is set by the multiroom sys-

tem, as explained on page 50 of this manual.
