System and Power Connections
The AVR 347 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’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 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 AVR’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 functions.
When a remote IR sensor is used to control non- Harman Kardon source equipment, we recom- mend that you make a direct connection or use an optional, external IR “blaster” connected to the Remote IR Carrier Output Jack +. If you are in doubt as to which IR Output jack to use for the equipment in your system, contact your dealer or installer, or the manufacturer’s support site and ask whether the unit to be controlled uses “full carrier” or “stripped” carrier IR commands. When “full carrier commands” are used, make the connection to the Remote IR Carrier Output Jack +. Otherwise, make the connection to the Remote IR Output Jack
as noted above.
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 your system`s requirement and distance from the AVR to the remote room, three 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, 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.
Option 3: Taking advantage of the AVR’s built- in
NOTE: For all options, you may connect an optional IR sensor (Harman Kardon He 1000) in the remote room to the AVR via an appropriate cable. Connect the sensor’s cable to the Multiroom IR Input ) on the AVR 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.
NOTE: The AVR 347’s multiroom system is only capable of distributing analog audio sources to the remote zone. Therefore, when connecting your digital audio equipment (e.g. CD or DVD players) as described on page 17, make sure to use both analog and digital audio connections to ensure that the devices will be available to the multiroom system.

AC Power Connections
This unit is equipped with one accessory AC outlet. It may be used to power accessory devices, but should not be used with
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 AVR 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 347’s incredible power and fidelity!
