Multiroom Operation

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

4on 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 E to call up the MAIN MENU (Figure 1). Next, press the

⁄/¤ Navigation Buttons DF so that the cursor is next to MULTI-ROOM, then press the OK/Enter Button E 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.

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 › but- ton DF 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 DF once so that the ➞ on-screen cursor is next to the MULTI IN line.

At the MULTI IN line, press the ‹/› buttons DF 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 DF once so that the ➞ on-screen cursor is next to the MULTI VOL line.

At the MULTI VOL line, press the ‹ / › but- tons DF 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 DF once so that the on-screen ➞ cursor is next to the BACK TO MASTER MENU line and press the OK/Enter Button

Eon the TC 30 or the Set Button Q on the ZR 10. If you have no other adjustments to make, press the Menu Button A 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 DF 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 DF so that MULTI is highlighted in reverse video and press the OK/Enter Button

Eon the TC 30 or the Set Button Q on the ZR 10.
