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.

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 acciden- tally 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 510.

3.Connect the output of any digital sources to the appropriate input connections on the AVR 510 rear panel. Note that the Optical and Coaxial digital inputs 31 32 #% may be used with a Dolby Digital or DTS source or the output of a conventional CD or LD player’s PCM (S/P-DIF) output.

4.Connect the coaxial or optical Digital Audio Outputs 33 on the rear panel of the AVR 510 to the matching digital input connections on a CD-R or MiniDisc recorder.

5.Assemble the AM Loop Antenna supplied with the unit as shown below. Connect it to the AM and GND screw terminals ¢.

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 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 sup- plied with the unit to make the connection.

7.Connect the front, center and surround speaker outputs fi to the respective speakers.

To ensure that all the audio signals are carried to your speakers without loss of clarity or reso- lution, we suggest that you use high-quality speaker cable. Many brands of cable are avail- able 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 constructed 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 recom- mend that you use cables with an AWG equiva- lent 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 stan- dards. 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 build- ing codes in your area.

When connecting wires to the speakers, be cer- tain 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 like terminals on the AVR 510 and speaker.

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 config-

uration. To ensure 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 pro- ceeding, 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 surround-left and surround-right speakers, even if the speakers are a different distance from the AVR 510.

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 con- nected to one or more subwoofer speakers. If you are using a powered subwoofer that does not have line-level input connections, follow the instructions furnished with the speaker for con- nection information.
