Installation and Connections
System and Power Connections
The AVR 4500 is designed for flexible use with multiroom systems, external control components and power amplifiers.
Main Room Remote Control Extension
If the receiver is placed behind a solid or smoked glass cabinet door, the obstruction may prevent the remote sensor from receiving commands. In this event, the remote sensor of any Harman Kardon or other compatible device, not covered by the door, or an optional remote sensor may be used. Connect the Remote IR Output of that device or the output of the remote sensor to the Remote IR Input jack .
If other components are also prevented from receiving remote commands, only one sensor is needed. Simply use this unit’s sensor or a remote eye by running a connection from the Remote IR Output jack to the Remote IR Input jack on Harman Kardon or other compatible equipment.
Multiroom IR Link
The key to remote room operation is to link the remote room to the AVR 4500’s location with wire for an infrared receiver and speakers or an amplifier. The remote room IR receiver (this can be an optional IR receiver or any other remotable Harman Kardon device in the remote room with IR sensor integrated) should be connected to the AVR 4500 via standard coaxial cable. Connect the Remote IR Output of the device or of the optional sensor with the Multiroom IR Input jack on the AVR4500’s rear panel.
If other Harman Kardon compatible source equipment is part of the main room installation, the Remote IR Output jack on the rear panel should be connected to the IR IN jack on that source device. This will enable the remote room location to control source equipment func- tions.
NOTE: All remotely controlled components must be linked together in a “daisy chain”. Connect the IR OUT jack of one unit to the IR IN of the next to establish this chain.
Multiroom Audio Connections
Depending on the distance from the AVR 4500 to the remote room, two options are available for audio connection:
Option 1: Use
Option 2: Place the amplifier that will provide power to the remote location speakers in the same room as the AVR 4500, and connect the Multiroom Output jacks on the rear panel of the AVR to the audio input of the remote room amplifier. Use the appropriate speaker wire to connect the optional power amplifier to the remote speakers.
2.5mm2 is recommended for long multiroom connections.
NOTE: In both options, you may connect an optional IR sensor in the remote room to the AVR 4500 via an appropriate cable. Connect the sensor’s cable to the Multiroom IR Input on the AVR 4500 and use the Zone II remote to control the room volume. Alternatively, you may install an optional volume control between the output of the amplifiers and the speakers.
External Audio Power Amplifier
Connections
If desired, the AVR 4500 may be connected to optional, external audio power amplifiers. When an external amplifier is used, connect the Preamp Out jacks to the inputs on the amplifier. Note that when external amplifiers or devices are used, volume is still controlled by the AVR, although additional volume controls on the external device may affect volume and output levels from the AVR.
AC Power Connections
This unit is equipped with two accessory AC out- lets. They may be used to power accessory devices, but they should not be used with high- current draw equipment such as power ampli- fiers. The total power draw to the Unswitched Outlet must not exceed 100 watts, that to the Switched Outlet 50 watts.
The Switched outlet will receive power only when the unit is on completely. This is recom- mended for devices that have no power switch or 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 outlets, and cannot be fully turned on using the outlet alone without a remote control command.
The Unswitched outlet will receive power as long as the unit is plugged into a powered AC outlet and the Main Power Switch 1 is on.
Finally, when all connections are complete, plug the power cord into a nonswitched
