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 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 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 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.
We recommend connecting the coaxial digital audio output of your DVD player to the Coax 1 Digital Audio Input , since that digital input is assigned to the DVD source by default.
The Video 2/Cable/Sat source defaults to the Optical 1 Digital Audio Input . If your cable television set-top box or satellite receiver is equipped with an optical digital audio output, we recommend that you connect it to this input to obtain the benefits of higher-quality digital audio (such as PCM, Dolby Digital 2.0 or Dolby Digital 5.1 signals when broadcast by your cable or satellite provider).
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.
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 connection uses 300-ohm twin-lead cable, you should use a 300-ohm-to-75-ohm adapter to make the connection.
7.Connect an MP3 player, iPod or portable CD to the Aux In minijack audio input to listen to music through the AVR 155. Usually the headphone jack on the portable player is the only one that can be used, and you have to adjust the volume to be at a reasonable level on the portable unit as well as on the AVR 155. If a fixed Line Out jack or dual phono plug output jacks are avail- able, using these with the proper cables may result in better sound quality.
8.Connect the front, center and surround speaker outputs 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 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 re- commend 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 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 certain to observe proper polarity. Note that the positive (+) terminal of each speaker connection now carries a specific color code as noted on page 8. However, most speakers will still use a red terminal for the postive (+) connection. Connect the “negative” or “black” wire to the same terminal on both the receiver and the 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 con- figuration. To assure 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.
9.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 connected 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 connection information.
10.If an external multi-channel audio source with 5.1 outputs such as an external digital processor/decoder, DVD-Audio or SACD player is used, connect the outputs of that device to the 6-Channel Direct Inputs .
Video Equipment Connections
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. To ensure best video per- formance S-Video sources should be connected to the AVR only with their S-Video In/Outputs, not with their composite video connectors too.
1.Connect a VCR’s audio and video Play/Out jacks to the 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.
2.Although any video device may be connected to these jacks, we recommend connecting your TV to the Audio 1 Audio/Video Input Jacks
so that you may take advantage of the fact that the remote control is preprogrammed with TV product codes for the Video 1 device.
For the same reason, we recommend connecting your video recorder, cable TV converter or satellite receiver to the Video 2 Audio/Video Input Jacks .
3.Connect the analog audio and video
outputs of a DVD or laser disc player to the DVD jacks .
