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 connections to your audio and video equipment.
Audio Equipment Connections
We recommend that you use
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,
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
* 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
4.Connect the Coaxial or Optical Digital Outputs on the rear panel of the AVR to the matching digital input connections on a
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
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
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
9.Connections to a subwoofer are normally made via a line level audio connection from the Subwoofer Output to the

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
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 .
