System Connections Parallel Output Connection In some multiroom systems, you may wish to have the same signal fed to multiple amplifiers to power additional rooms on a single zone. To do this, connect the Main Amp Output Jacks , to the input of the additional, optional power amplifiers. Note that signal feed sent to these jacks is the feed from the Main Amplifier Input Jacks ⁄. The source connected to the Channel 3 Input Jacks › may not be sent to a parallel output. Infrared Control Connections The PA 4000 allows you to anchor a multiroom installation by receiving IR remote control commands from remote rooms and, where compatible, using them to control other sourcecontrol components. IR connections are made as follows: Connect the incoming IR feed from a remote room to the appropriate Remote IR Sensor Input ‹. To send the incoming IR signals onward to source components or an AV receiver or other controller, connect the IR Remote Control Output § to the IR input of the desired component to be controlled. When the PA 4000 is used in conjunction with a compatible, multiroom-equipped, Harman Kardon AV receiver, such as the AVR 7000, AVR 510 or AVR 310, you may also use the remote-room IR commands to turn the multiroom feature of the AVR on and off while the volume is controlled in the PA 4000. To enable this function, slide the MR On/Off Command Switch ¶ to the left so that it is over the word "ON". Notes for Infrared Connections: • When the optional keypads incorporating IR sensors from third-party suppliers are connected to any of the Remote Keypad Inputs fl, do not make any connections to the Remote IR Sensor Input ‹ for that amplifier channel pair. • When the optional keypads are connected, the output of the IR sensor built in to the keypad should be connected to the AV receiver or other devices to be controlled using the IR Remote Control Output §. Keypad Connections The PA 4000 is designed for use with optional, compatible remote room keypads. These keypads will control the volume and power on/off for a particular room's feed. In addition, the keypad may include a built-in IR remote sensor that may be used to carry control signals to source equipment, a receiver or a multiroom controller. When these keypads are used, connect the keypad from a remote room to the Remote Keypad Input Jack fl matching the respective room location. When the PA 4000 is used in conjunction with a compatible, multiroom-equipped, Harman Kardon AV receiver, such as the AVR 7000, AVR 510 or AVR 310, you may also use the remote room IR commands to turn the multiroom feature of the AVR on and off while the volume is controlled in the PA 4000. To enable this function, slide the MR On/Off Command Switch ¶ to the left so that it is over the word "ON". NOTE: The connection jack used for the keypads is an RJ-45-style jack that is identical to that used for some telephone or data applications. However, these jacks are used by the PA 4000 solely for use with compatible keypads. They should not be used for any other purpose or connected to any other device. AC Power Connection The final step in the installation of the PA 4000 is to connect the power cord. First, connect the female end of the cord into the AC Power Cord Jack ª on the rear panel. Once the cord as been firmly connected to the PA 4000, insert the plug end into an AC power outlet. SAFETY NOTES: • Due to the current draw of the PA 4000, DO NOT connect the power cord to the accessory outlet on audio/video components. • Should the power cord become lost or damaged, be certain to replace it with a replacement that meets or exceed the original specifications. Use of power cords with insufficient capacity, such as those used with computers or office equipment, may create a safety hazard. 12 SYSTEM CONNECTIONS
