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.

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

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 L to bring the MASTER MENU (Figure 7) to the screen. Press the ⁄ button E twice, until the on-screen ➞ cursor is next to the MULTI-ROOMline. Press the Set button F to enter the MULTI-ROOMmenu (Figure 24).

When the MULTI-ROOMmenu 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 E so that ON is highlighted. If you do not wish to turn the system on at this time or to proceed to the next step, press the ¤ Button

Eonce so that the ➞ on-screen cursor is next to the MULTI IN line.

At the MULTI IN line, press the ‹/› buttons

Euntil the desired Audio/Video input to the multi-room system appears in the highlighted video. When the selection has been made, press the ¤ button E once so that the ➞ on-screen cursor is next to the MULTI VOL line.

At the MULTI VOL line, press the ‹ / › buttons E 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 E once so that the on-screen ➞ cursor is next to the BACK TO MASTER MENU line and press the Set button F. If you have no other adjustments to make, press the OSD button L 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 L to bring the MASTER MENU (Figure 7) to the screen. Next, press the ¤ Button E until the ➞ cursor is next to the MULTI ROOM line. Press the Set Button

Fto 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

Eso that MULTI is highlighted in reverse video and press the Set Button F.

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.
