MULTIROOM OPERATION

The AVR 745 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 sec-

nd zone in the house while a separate source is lis-

ened to in the main room. In addition to providing for

control over the selection of the remote source and its

volume, the AVR 745 offers a comprehensive range of

options for powering the speakers in the second zone.

• Using the line-level

Multiroom Audio/Video

Outputs

8L, the selected source may be fed to

optional, external power amplifiers that may be

atched 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 745

via a single Category 5/5e or higher cable, so that

remote zone speakers may be powered directly

from the A-BUS module without the need for addi-

tional power, IR sensor or volume control wires to

be run to the second zone.

In addition, the AVR 745 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 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 ser

vices

of a specially trained installer may be required.

Regardless of who does the work, please remember

that local building codes may gover

n in-wall electrical

work, including proper specification of any wiring used

and the way in which it is connected. You are respon-

sible for making certain that all multiroom installation

work is done properly and in compliance with all appli-

cable codes and regulations.

or standard installations,

follow the instructions shown

on page 17 for the connection of speaker wire and IR

remote wiring to the AVR 745.

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 this page.

For installations where A-BUS modules are used, fol-

low the instructions provided with the A-BUS remote

modules or keypads. Additional information will also be

ade available through the Harman Kardon Web site

t www.harmankardon.com.

RS-232 Control

he AVR 745 provides the capability for full bidirec-

tional remote control from compatible computers or

specialized remote control systems. RS-232 program-

ming requires specialized programming knowledge

and for that reason we recommend that it only be

one by qualified professionals. For more information

on using the

S-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 745 needs to be configured for

multiroom operation.To change a setting from its facto-

ry default, you will use the

MULTI-ROOM

SETUP

menu. With the TC 30, first press the

Devices Button 4 on the TC 30 remote and then

press the

Screen Button 6 next to AV

Receiver

and press the Menu Button A.

With the ZR 10 remote, press the

OSD Button

∫

to call up the MAIN MENU (Figure 1). Next,

press the

⁄

Navigation Buttons D

that the cursor is next to

MULTI-ROOM, then

press the

OK/Enter Button E on the TC 30

or the

Set Button

on the ZR 10. When the

MULTI-ROOM SETUP menu (Figure 33)

appears, follow the instructions shown below to make

any needed configuration adjustments.

Figure 33

When the MULTI-ROOM menu appears

, the

cursor will be at the

MULTI-ROOM line.

Since

this line is used to turn the system on and off, don’t

make an adjustment here unless you wish to turn the

system on at this time

o turn the system on, press the

› Navigation Button D

so that ON is high-

lighted.

If you do not wish to turn the system on at this

time, or to proceed to the next step, press the

⁄

Navigation Buttons D

so that the on-screen

cursor is next to the

MULTI IN line.

t the

ULTI IN

ine, press the

‹

›

avigation

Buttons

until the desired input to the multi-

room system appears in the highlighted video. In addi-

tion to direct selection of any active input source, you

ay also select the

SP DOWNMIX

ode,

which outputs a two-channel down-mixed version of

multi-channel digital sources. When the selection has

been made, press the

Navigation Button

once so that the cursor is next to

ULTI VOL

At the

MULTI VOL line, press the

‹

›

Navigation Buttons D

until the desired vol-

ume level for the multiroom system is entered. DO

NOT use the regular volume control knobs for this set-

ting. When all settings for the multiroom setup have

been made, press the

⁄

Navigation Buttons

until the cursor is next to the BACK TO

MASTER MENU

line. If you have no other

adjustments to make, press the

Menu Button A

or the OSD Button

∫

to exit the menu system.

Surround Channel Amplifier Assignment

The AVR 745 is equipped with seven full-power

amplifier channels to allow for complete 7.1-channel

operation. However, if your system is only configured

for 5.1 channels in the main listening room, you may

take advantage of the “extra” two channels by using

them to power speakers placed in a second zone

location. This enables you to use the multiroom capabili-

ties of the AVR 745 without the cost of an additional,

external power amplifier.

To change the setting so that the Surround Back

amplifiers

are fed by the source selected through

the

Multiroom

system rather than the SBL/SBR

channels of the main room, make certain that the

MULTI-ROOM SETUP menu (Figure 33)

is on the screen; then press the

‹

›

Navigation

Button

so that the cursor is pointing to

the

SB AMPS line.

Press the

‹

›

Naviga

tion

Buttons

so that MULTI is shown in

highlighted video. When this change is made, connect

the wires feeding the remote zone speakers to the

Surround Back/Multiroom Speaker Outlets E.

When the SBL/SBR speakers are set for

multiroom

operation, you may still configure the AVR 745 for 7.1

modes in the main listening room by making certain

that the

SURR BACK line in the SPEAKER

SIZE

menu (Figure 27) is set to SMALL or

LARGE, as shown in the instructions on page xx.

When that is done, the word

MULTI will appear

next to the large or small designator to alert you to the

fact that the inter

nal SBL/SBR amplifiers are assigned

to the multiroom system, and that an optional, external

two-channel power amplifier must be connected to the

SBL/SBR Preamp Outputs ¡ in order to use sur-

round back channel speakers.
