Installation and Connections 15 NOTE: While most speaker manufacturers adhere to an industry convention of using black terminals for negative and red ones for positive, some manufacturers may vary from this configuration. To assure proper phase, and optimal performance, consult the identification plate on your speaker, or the speaker's manual to verify polarity. If you do not know the polarity of your speaker, ask your dealer for advice before proceeding, or consult the speaker's manufacturer. 7. Connections to a subwoofer are made via a line level audio connection from the Subwoofer Output ª to the line level input of a subwoofer with a built-in amplifier. If a passive subwoofer is used, the connection first goes to a power amplifier, which will be connected to one or more subwoofer speakers. Video Equipment Connections Video equipment is connected in a fashion similar to audio components. Again, the use of high-quality interconnect cables is recommended to preserve signal quality. 1. Connect a VCR's audio and video Play/Out jacks to the Video 1 In jacks £ on the rear panel. The audio and Record/In jacks on the VCR should be connected to the Video 1 Out jacks ¢ on the AVR45. 2. Connect the audio and video outputs of a satellite receiver, cable TV converter or television set or any other video source to the Video 2 In jacks fl. 3. Connect the audio and video outputs of a DVD or laser disc player to the DVD jacks ¶. 4. Connect the TV Monitor Out ‡ jacks on the receiver to the video input of your television monitor or video projector. System and Power Connections The AVR45 is designed for flexible use with external control components and power amplifiers. These connections are easy to make during an initial installation, or at a later date should you choose to upgrade your system. 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, an optional remote sensor may be used. Connect the output of the remote sensor to the Remote Cont. In jack a. If other components are also prevented from receiving remote commands, only one sensor is needed. They may use this unit's sensor or a remote eye by running a connection from the Remote Cont. Out jack b to the Remote In jack on Harman Kardon or other compatible equipment. External Audio Power Amplifier Connections If desired, optional external power audio power amplifiers may be used with the AVR45. Connections to these amplifiers are made by using audio interconnect cables connected to both the Preamp Outputs • on the rear panel and the audio input jacks of the external amplifiers. External Audio Decoder Connection To provide for the ultimate flexibility, the AVR45 may be used in conjunction with optional, external decoders for digital audio systems other than the AVR45's own built-in Dolby Digital system. If an external decoder is used, connect the output jacks of the decoder to the 6-Channel Direct inputs ∞, making sure to match channels. These jacks may also be used for connections to devices usch as DVD players or High Definition Television (HDTV) sets or decoders that feature built-in digital surround decoders. Although the digital decoding system in the AVR45 will typically provide audio performance that is superior to other decoders, you may use these jacks to provide an additional 6-channel input for connection to a DVD player or HDTV set with a built-in decoder and discrete 6-channel analog outputs. 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 equipment such as power amplifiers. The total power draw may not exceed 50W to each outlet. The Switched › outlet will receive power only when the unit is on. This is recommended for devices that have no power switch, or a mechanical power switch that may be left in the "ON" position. NOTE: Devices with electronic power switches may only go into a Standby mode when plugged in here. The Unswitched ‹ outlet will receive power as long as the unit is plugged into a powered AC outlet. Finally, when all connections are complete, plug the power cord into a nonswitched 120-volt AC wall outlet. You're almost ready to enjoy the AVR45!
