MULTIROOM OPERATION 55

ENGLISH

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 audio/video source to

a second zone in the house while separate

source is listened to in the main room. In addi-

tion 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 Output Jacks



, 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

ZR 10 remote included with the unit may be

transmitted to the unit, while standard IR

input/output jacks allow the remote zone’s com-

mands 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 sys-

tem 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 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 55.

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 avail-

able through the Harman Kardon Web Site at

www.harmankardon.com.

RS-232 Control

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

provides the capability for full biderectional

remote control from compatible computers or

specialized remote control systems. RS-232 pro-

gramming 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.

To change a setting from its factory default, you

will use the

MULTI-ROOM SETUP menu.

With the TC 30, first press the Devices Button

on the TC 30 remote and then press the

Screen Button

next to AV RECEIVER

and press the Menu Button

. With the ZR

10 remote, press the OSD Button E to call up

the

MAIN MENU (Figure 1). Next, press the

⁄

Navigation Buttons

F so that the

cursor is next to

MULTI-ROOM, then press

the OK/Enter Button

on the TC 30 or the

Set Button Q on the ZR 10. When the

MULTI-ROOM SETUP menu (Figure 32)

appears, follow the instructions shown below to

make any needed configuration adjustments.

Figure 32

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

› but-

ton

F 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

F once so that the ➞ on-screen cursor is

next to the

MULTI IN line.

At the

MULTI IN line, press the

‹

›

buttons

F until the desired Audio/Video input to

the multi-room system appears in the highlighted

video. In addition to direct selection of any active

input source, you may also select the

DSP

DOWNMIX

mode, which outputs a two-chan-

nel down-mixed version of multi-channel digital

sources. When the selection has been made,

press the

button

F once so that the ➞

on-screen cursor is next to the

MULTI VOL

line.

At the

MULTI VOL line, press the

‹

›

but-

tons

F 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

F once so that the on-screen ➞

cursor is next to the

BACK TO MASTER

line and press the OK/Enter Button

on the TC 30 or the Set Button Q on the

ZR 10. If you have no other adjustments to make,

press the Menu Button

or the OSD

Button E 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. Next, press the

Button

F until the ➞ cursor is next to the

SB AMPS line.

To change the setting so that the Surround Back

amplifiers are fed by the source selected through

the Multiroom system, press the

‹

›

Buttons

F so that MULTI is highlighted in

reverse video and press the OK/Enter Button

on the TC 30 or the Set Button Q on the

ZR 10.
