INSTALLATION AND CONNECTIONS

zone, connect the speakers for the remote room loca- tion to the Surround Back/Multiroom Speaker Outputs fi. Before using the remote room, you will need to configure the amplifiers for surround operation by changing a setting in the MULTIROOM menu, following the instructions shown on page 44.

NOTE: For all options, you may connect an optional IR sensor in the remote room to the AVR 445 via an appropriate cable. Connect the sensor’s cable to the Multiroom IR Input e on the AVR 445 and use the ZR 10 remote to control the room volume. You may install an optional volume control between the output of the amplifiers and the speakers in options 1 and 2.

A-BUS®Installation Connections

The AVR 445 is among the few receivers available that offer built-in A-BUS/READYoperation. When used with an optional A-BUS product, you have all the ben- efits of remote zone operation without the need for an external power amplifier.

To use the AVR 445 with an approved A-BUS prod- uct, simply connect it to the AVR 445 using standard Category 5 wiring that is properly rated for the specific in-wall installation. Terminate the wiring at the receiver end to a standard RJ-45 connector in compliance with the instructions furnished with the A-BUS product.

No further installation or adjustment is needed, as the A-BUS jack on the AVR 445 routes the signals to their proper destination for power, signal source and control. The output fed to the A-BUS jack is determined by the AVR 445’s multiroom system and menus.

RS-232 Connections

The AVR 445 is equipped with an RS-232 Serial Connection Port a that may be connected to a compatible, optional, external computer, keypad or control system for bidirectional communications that enable the external system to control the AVR, and for the AVR to report status and handshake data back to the controller. Use of the RS-232 port for this type of control requires specific technical knowledge, and we recommend that any connection and programming for control be made by a trained installer or technician familiar with the equipment being used.

The physical connection to the AVR 445’s RS-232 port is a standard D-SUB 9 connection, but to ensure compatible and proper operation, specific software commands and pin wiring schemes may be required.

USB Connections

The AVR 445 is one of the few A/V receivers to offer a USB connection that may be used for both playback of compatible audio content from a computer and for loading of system updates (when available).

The physical connection between a computer and the AVR is a simple one, requiring only a cable with a USB “A” type connector on one side and a USB “Mini B” on the other.

Connect the larger, “A” connector on the cable to your computer or a USB hub and the end with the “Mini” USB connector to the USB Port W on the AVR’s rear panel.

NOTES ON USB:

•The USB port on the AVR 445 is to be used only for connection to a computer or a hub connected directly to a computer. DO NOT connect it to other devices such as portable audio players, card readers, USB memory storage devices, external hard drives, USB accessories, digital cameras or cellular phones. Connection to these devices may cause damage to the device and/or the AVR that is not covered by the AVR’s warranty.

•The AVR 445’s USB connection may only be used for audio playback and system upgrades. It may not be used for other purposes, such as system control, video or still-image playback.

Trigger Connection

The AVR 445 is equipped with a low-voltage trigger that may be used to control a wide variety of compati- ble, optional devices that respond to voltage actuation commands. This includes external audio power amplifiers, video screens, motorized blinds and other compatible products in a home theater or automation system. Due to the complexity of interfacing with power- controlled devices, we strongly recommend that they be installed by a qualified professional.

The Trigger Output H delivers 6 volts DC when activated, and removes the voltage when the AVR is turned off. The connection is a 3.5mm mono mini plug with the signal on the center pin (“tip”) and the outer shaft (“ring”) acting as the negative or ground connection.

The Trigger Output H is for use with devices such as power amplifiers that you wish to activate whenever the AVR is turned on, regardless of the input selected.

After checking for voltage, current and polarity com- patibility between the device being controlled and the AVR, simply connect one end of the trigger cable to the device being controlled and the other end to the Trigger Output H on the AVR.

IMPORTANT NOTE ON THE TRIGGER CONNECTION: The current draw from the trigger jack cannot exceed 1.0mA.

XM Radio Connections

XM Radio is a satellite-delivered, subscription-based, programming service that provides a wide range of music, sports, news and information programming with digital audio quality. The AVR 445 is XM Connect & Play-ready, which means that you can easily add the XM service to your home audio system by purchasing an XM antenna module, activating an account with XM and then making a simple, single-cable connection to your AVR.

To purchase an XM antenna module, consult your dealer, or contact XM Radio at www.xmradio.com. After following the instructions packed with the mod- ule, place the XM antenna near a south-facing window and run the cable to the AVR. Connect the plug at the end of the cable to the XM Ready Input V. Once the connection is made, follow the instructions on page 39 for more information on listening to XM Radio.

NOTES on XM Radio:

•XM Radio requires the purchase of additional, optional hardware and a separate subscription to the XM service.

•XM Radio is available only in the continental United States and Canada. It is not available in Alaska

or Hawaii.

•XM reception requires that the antenna be able to “see” the XM satellites or receive a signal from one of the XM ground-based repeaters. Depending on your installation and location, XM service may not be available in some areas.

AC Power Connections

This unit is equipped with an accessory AC outlet that may be used to power accessory devices, but it should not be used with high-current draw equipment such as power amplifiers. The total power draw may not exceed 100 watts.

This Switched AC Accessory Outlet ‡ is powered only when the unit is on. This is recommended only for devices that have a mechanical power switch that may be left in the “ON” position.

NOTE: Many audio and video products go into a Standby mode when they are used with switched out- lets. This type of product may not operate properly when used with the switched outlet.

The AVR 445 features a removable power cord that allows wires to be run in advance to a complex installation so that the unit itself need not be installed until it is ready for connection. When all needed connections have been made, connect the AC power cord to the AC Power Cord Jack ·.

The AVR 445 draws significantly more current than other household devices, such as computers, that use removable power cords. For that reason, it is important that only the cord supplied with the unit (or a direct replacement of identical capacity) be used.

Once the power cord is connected, you are almost ready to enjoy the AVR 445’s incredible power and fidelity!
