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 configu- ration. To assure proper phase and optimal per-

Audio Equipment Connections

We recommend that you use high-quality inter- connect cables when making connections to source equipment and recorders to preserve the integrity 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 possibility 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 so high that the signal is distorted.

2.Connect the analog Play/Out jacks of a cas- sette deck, MD, CD-R or other audio recorder to

the Tape Input jacks . Connect the analog Record/In jacks on the recorder to the Tape

Output jacks

on the AVR.

3.Connect the digital output of any digital sources such as a CD or DVD changer or player, advanced video game, a digital satellite receiver, HDTV tuner or digital cable set-top box or the output of a compatible computer sound card to the Optical and Coaxial Digital Inputs

* Ó.

4.Connect the Coaxial or Optical Digital Outputs on the rear panel of the AVR to the matching digital input connections on a CD-R or MiniDisc recorder.

6. Connect the supplied FM antenna to the FM

(75 ohm) connection . The FM antenna may be an external roof antenna, an inside powered or wire lead antenna or a connection from a cable system. Note that if the antenna or connec- tion uses 300-ohm twin-lead cable, you should use a 300-ohm-to-75-ohm adapter to make the connection.

7. Connect the front, center and surround

speaker outputsto the respective speakers.

To ensure that all the audio signals are carried to your speakers without loss of clarity or resoluti- on, 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 the receiver, the type of speakers you use, personal prefer- ences 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 constructed of fine, multistrand copper with an area greater than 2 mm2.

Cable with an area of 1.5 mm2 may be used for short runs of less than 4 m. We do not recom- mend that you use cables with an area less than 1 mm2 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 any appropriate testing agency standards. Questions about running cables inside walls should be referred to your installer or a licensed electrician who is familiar with the applicable local building codes in your area.

When connecting wires to the speakers, be cer- tain to observe proper polarity. Note that the positive (+) terminal of each speaker connection now carries a specific color code as noted on page 7. However, most speakers will still use a red terminal for the postive (+) connection. Con- nect the “negative” or “black” wire to the same terminal on both the receiver and the speaker.

formance, 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.

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 sur- round-left and surround-right speakers, even if the speakers are a different distance from the AVR.

8.Connections to a subwoofer are normally made via a line level audio connection from the

Subwoofer Output to the line-level input of a subwoofer with a built-in amplifier. When a passive subwoofer is used, the connection first goes to a power amplifier, which will be connect- ed to one or more subwoofer speakers. If you are using a powered subwoofer that does not have line-level input connections, follow the instruc- tions furnished with the speaker for connection information.

9.If an external multi-channel audio source with 5.1 or 7.1 outputs such as an external digital processor/decoder, DVD-Audio or SACD player is used, connect the outputs of that device to the

8-Channel Direct Inputs .

Analog Video Equipment

Connections

Analog video equipment is connected in the same manner as 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 or Video 2 In jacks

on the rear panel. The Audio and Video Record/In jacks on the VCR should be connected

to the Video 1 Out jacks

on the AVR.
