JBL AVR480 manual Installation And Connections, Audio Equipment Connections

INSTALLATION AND CONNECTIONS

After unpacking the unit, and placing it on a solid surface capable of supporting its weight, you will need to make the connec- tions to your audio and video 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 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 pos- sibility of accidentally sending audio or transient signals to the speakers that may damage them.

IMPORTANT NOTE: In order to clearly identify all connectors and simplify installation, as per the new EIA/CEA-863 standard, all connections are color-coded as follows:

For speakers and audio in/outputs: white (left, speakers front) and red (right, speakers front)

For speakers: green (center), blue (left surround) and gray (right surround)

For audio output: purple (subwoofer)

For composite video in/outputs: yellow

For coaxial digital audio in/outputs: orange

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 cassette 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 AVR480.

3.Connect the digital output of any digital device to the appropriate input connections on the AVR480 rear

panel. Note that the Optical and

Coaxial Digital Inputs may be used with a Dolby Digital or DTS source or the output of a conventional CD, MD or LD player’s PCM (S/P-DIF) output.

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

5.Assemble the AM Loop Antenna supplied with the unit so that the tabs at the bottom of the antenna loop snap into the holes in the base. Connect it to the AM and GND Screw Terminals a.

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 connection uses 300-ohmtwin-lead cable, you must use a 300-ohm-to-75- ohm adapter to make the connection.

Select the position corresponding to the country in which the AVR will be used (China, Singapore or Korea) so that the FM tuner’s frequency incre- ments will be correct. If the AVR will be used in a country other than one of those listed, contact your JBL dealer for information on which position should be used. (See page 31.)

7. Connect the front, center and surround

Speaker Outputs to the respective speakers.

To ensure 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 the 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 an area greater than 2mm2 (14-gauge or smaller; when specifying cable size in terms of gauge, remember that the lower the number, the thicker the cable).

Cable with an area of 1.5mm2 (16-gauge) may be used for short runs of less than 4m (10 feet). We do not recommend that you use cables with an area less than 1mm2 (18-gauge) 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 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 both the receiver and the speaker. Similarly, the “positive” or “red” wire should be connected to the corresponding colored terminals on the AVR480 and speaker.

NOTE: While most speaker manufactur- ers adhere to an industry convention of using black terminals for negative and red ones for positive, some manufacturers may vary from this configuration. To ensure proper phase and optimal perform- ance, 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.
