Installation and Connections

System Installation

After unpacking the unit, and placing it on a solid surface capable of supporting its weight, you will need to make the connections to your audio and video equipment. These steps need to be done only when the receiver is first installed, or when a change is made to the input source equipment.

Audio Equipment Connections

We recommend that you use high-quality interconnect cables when making connec- tions to source equipment and recorders to preserve the quality of the signals.

When making connections to audio source equipment or speakers it is always a good practice to unplug the unit from the AC wall outlet. This prevents any pos- sibility of accidentally sending audio or transient signals to the speakers that may damage them.

1.Connect the analog output of a CD player to the CD inputs ¤.

NOTE: When the CD player has both fixed and variable audio outputs it is best to use the fixed output unless you find that the input to the receiver is so low that the sound is noisy, or high that the signal is distorted.

2.Connect the Play/Out jacks of a cas- sette deck, MD or other audio recorder to the Tape Monitor In jacks c. Connect the Record/In jacks on the recorder to the Tape Monitor Out jacks d on the AVR45.

3.Connect the output of any digital sources to be used to the appropriate connections on the AVR45 rear panel. Note that the Optical and Coaxial digital inputs á ¡ may be used with either a Dolby Digital (AC-3) source or the output of a conventional CD or LV player’s PCM (SP/DIF) output.

4.Assemble the AM Loop Antenna sup- plied with the unit as shown below. Connect it to the AM and GND screw terminals Á.

5.Connect an FM antenna to the FM (75 ohm) connection ª. The FM antenna may be an external roof antenna, an inside powered or wire lead antenna or a connection from a cable TV system. Note that if the antenna or connection uses 300-ohm twin-lead cable, you must use the 300-ohm-to-

75-ohm adapter supplied with the unit to make the connection.

6.Connect the front, center and surround speaker outputs â Ú l to the respective speakers.

To assure that all the audio signals are carried to your speakers without loss of clarity or resolution, we suggest that you use high-quality speaker cable. Many brands of cable are available, and the choice of cable may be influenced by the distance between your speakers and this receiver, the type of speakers you use, personal preferences and other factors.

Your dealer or installer is a valuable resource to consult in selecting the proper cable.

Regardless of the brand of cable selected, we recommend that you use a cable con- structed of fine, multistrand copper with a gauge of 14 or smaller. Remember that in specifying cable, the lower the number, the thicker the cable.

Cable with a gauge of 16 may be used for short runs of less than ten feet. We do not recommend that you use cables with an AWG equivalent of 18 or higher due to the power loss and degradation in performance that will occur.

Cables that are run inside walls should have the appropriate markings to indicate listing with UL, CSA or other appropriate testing agency standards. Questions about running cables inside walls should be referred to your installer or a licensed electrical contractor who is familiar with the NEC and/or the applicable local building codes in your area.

When connecting wires to the speakers, be certain to observe proper polarity. Remember to connect the “negative” or “black” wire to the same terminal on the receiver and the speaker. Similarly, the “positive” or “red” wire should be con- nected to the like terminal on the AVR45 and speaker.

We also recommend that the length of cable used to connect speaker pairs be identical. For example, use the same length piece of cable to connect the front left and front right or surround left and surround right speakers, even if the speakers are a different distance from the AVR45.
