Multiroom Operation

Multiroom

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 lis- tened to in the main room. In addition to provid- ing for control over the selection of the remote source and its volume, the AVR offers a com- prehensive range of options for powering the speakers in the second zone.

•Using the line-level Zone 2 Outputs &, the selected source may be fed to optional, external power amplifiers that may be matched to the specifics of the installation (Zone 2 Outputs on AVR 355 only).

•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. (Please note that the A-BUS functionality is featured in AVR 355 only).

In addition, the AVR includes a remote IR sensor input so that remote control commands from the Zone II remote included with the (AVR 355 only) or from the main remote when set to Zone 2 with the slide Switch Z 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 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 18-19 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 below.

For installations where A-BUS modules are used, follow the instructions provided with the A-BUS remote modules or keypads.

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 AVR button Y to bring the main menu to the screen. Press the ⁄/¤ Button F until the ZONE 2 menu line is highlighted in blue. Press the OK button X to enter the menu.

Figure 18

When the ZONE 2 menu appears, the blue cursor bar will be at the Status: Off 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 OK Button X once, to turn it off again, press once more. If you do not wish to turn the system on at this time or to pro- ceed to the next step, press the ¤ Button F once so that the blue cursor bar is highlighting the Source line.

At the Source line, press the press the OK Button to cause the Source List to slide in from the right. Use the Up/Down Button F to select the source.. When the selection has been made, press the OK Button X to confirm your choice, and continue to the Volume line by pressing the ¤ Button F.

At the Volume line, press the ‹/ › buttons F or hold them pressed until the desired vol- ume level for the multi-room system is entered. DO NOT use the regular volume control knobs for this setting.

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 AVR Button Y to bring the main menu (Figure 1) to the screen. Next, press the ¤ Button F until the Zone 2 menu line is highlighted in blue. Press the OK Button X to enter the Zone 2 menu.

The Surround Back Amps line is used to assign the surround back channels for multizone opera- tion. Select the Zone 2 setting when multizone listening is desired. If the multizone system is not in use, this setting may be changed to Main Room to accommodate a 7.1-channel system. When the multiroom system is turned off, this line will always display the MAIN setting. When the multiroom system is turned on, this line will always display the MULTI setting, reflecting that the surround back channels are always assigned to the remote zone when the multiroom system is used.

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 system, as explained above.
