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 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
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.
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 connec-
tion uses 300-ohm twin-lead cable, you should use a 300-ohm-to-75-ohm adapter to make the connection.
7.With the AVR 140 turned off, connect the
optional Harman Kardon 
to 
Digital Media Player (DMP) Connector . Your compatible Apple® iPod® may be docked in 
when you wish to use it as your audio source device. Video materials stored on the iPod are not able to be viewed using the AVR.
8. Connect the front, center and surround
speaker outputsto 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 influen- ced 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 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 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 proceeding, 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.
Note that it is not possible to use the AVR 140 in a 7.1-channel configuration. Any source informa- tion that the AVR receives or derives for the sur- round back left and right channels, e.g. through
the 6/8-Channel Direct Inputs or during 7-
channel Stereo processing, is combined and out- putted to the single-channel Surround Back Speaker Outputs .
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 connect- ed to one or more subwoofer speakers. If you are using a powered subwoofer that does not have line-level input connections, follow the instruc- tions 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
8-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 1 or 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 video recorder to the Video 1 Audio/Video
Input Jacks so that you may take advan- tage of the fact that the remote control is prepro- grammed with video recorder product codes for the Video 1 device.
For the same reason, we recommend connecting your cable TV converter or satellite receiver to the
Video 2 Audio/Video Input Jacks , and your television to the Video 3 Audio/Video Input Jacks Ô.
