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 prac- tice to unplug the unit from the AC wall outlet. This prevents any possibility of accidentally send- ing audio or transient signals to the speakers that may damage them.
Important Note : In order to clearly identify all connectors and simplify nstallation, as per the new EIA/CEA-863 standard, all connections are colour 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 Grey (Right Surround).
For Audio Output: Purple (Subwoofer).
For Composite Video In/Outputs: Yellow.
For 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 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 1550. |
3.Connect the digital output of any digital device to the appropriate input connections on the AVR 1550 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 Outputs on
the rear panel of the AVR 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 system. Note that if the antenna or con- nection uses 300-ohm twin-lead cable, you must use a 300-ohm-to-75-ohm adapter to make the connection.
7. Connect the front, center and surround speak-
er outputs | to the respective speakers. |
To assure that all the audio signals are carried to your speakers without loss of clarity or resolu- tion, 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 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 1mm2 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 applicable local building 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 the same terminals on the AVR 1550 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 configu- ration. To assure proper phase and optimal per- 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 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 sur- round-left and surround-right speakers, even if the speakers have a different distance from the AVR 1550.
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.
Note: Speaker sets with two front satellites and a passive subwoofer must be connected to the
front speaker outputs | only rather than to the |
Subwoofer Output . | |
Video Equipment Connections
Video equipment is connected in the same man- ner as audio components. Again, the use of high- quality interconnect cables is recommended to preserve signal quality. To ensure best video per- formance S-Video sources should be connected to the AVR 1550 only with their S-Video In/ Outputs, not with their composite video connec- tors too.
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 con-
nected to the Video 1 jacks | on the |
AVR 1550. | |
2.Connect the analog audio and video outputs of a satellite receiver, cable TV converter or tele- vision set or any other video source to the
Video 2 (if not in use) or Video 3 % jacks.
3.Connect the video outputs of a DVD or laser
disc player to the DVD jacks .
4. Connect the Video Monitor Out jacks on the receiver to the composite and S-Video input of your television monitor or video projector.
Video Connection Note:
•S-Video or Composite video signals may only be viewed in their native formats and will not be converted to the other format.
