INSTALLATION AND CONNECTIONS

operation by changing a setting (following the instruc- tions shown on page 39) in the MULTI-ROOM SETUP menu.

NOTE: For all options, you may connect an optional IR sensor in the remote room to the DPR 2005 via an appropriate cable. Connect the sensor’s cable to the

Multiroom IR Input on the DPR 2005 and use the Zone II remote to control the room volume. Alter- natively, you may install an optional volume control between the output of the amplifiers and the speakers.

A-BUS®Installation Connections

The DPR 2005 is among the very few receivers avail- able today that offer built-in A-BUS Ready operation. When used with an optional A-BUS keypad or control module, you have all the benefits of remote zone operation without the need for an external power amplifier.

To use the DPR 2005 with an approved A-BUS prod- uct, simply connect the keypad or module that is in the remote room to the DPR 2005 using standard Category 5 wiring that is properly rated for the in-wall use specific to the installation. Terminate the wiring at the receiver end to a standard RJ-45 connector in compliance with the instructions furnished with the A-BUS module.

No further installation or adjustment is needed, as the A-BUS jack on the DPR 2005 routes the signals in and out of the keypad to their proper destination for power, signal source and control. The output fed to the A-BUS jack is determined by the DPR 2005’s multiroom system and menus.

RS-232 Connections

The DPR 2005 is equipped with an RS-232 Port a that may be used for two purposes. When the port is connected to a compatible, optional, external computer, keypad or control system the DPR 2005 is capable of bi-directional communications that enable the external system to control the DPR, and for the DPR 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 RS-232 port may also be used as an access point through which the DPR 2005’s operating system and surround mode memories may be updated via connection to a compatible computer. At the time that an upgrade is available, instructions for making the connection and installing the upgrade will be available through the Product Support area of the Harman Kardon Web site at harmankardon.com.

The physical connection to the DPR 2005’s RS-232 port is a standard D-SUB 9 connection but to assure compatible and proper operation, specific software commands and pin wiring schemes may be required.

AC Power Connections

This unit is equipped with two accessory AC outlets. They may be used to power accessory devices, but they should not be used with high-current draw equip- ment such as power amplifiers. The total power draw to each outlet may not exceed 100 watts.

The Switched AC Accessory Outlet d is powered only when the unit is on. This is recommended 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 Unswitched AC Accessory Outlet c is powered as long as the DPR is plugged into a powered AC outlet.

The DPR 2005 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 b.

The DPR 2005 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 DPR 2005’s incredible power and fidelity!
