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).
NOTE: If you wish for your digital source device to be available for use by the multiroom system, you will need to connect its analog audio outputs to the appropriate inputs on the
AVR 347, as the multiroom system is not capable of distributing digital signals to the remote zone.
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.With the AVR 347 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.
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 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 configuration. 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 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.
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 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.
10.If an external multi-channel audio source with 5.1 outputs such as an external digital processor/decoder, DVD-Audio, SACD, Blu-ray or HD-DVD 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 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 only with their S-Video In/Outputs, not with their composite video connectors too.
If you have already connected a source device to one of the HDMI inputs as explained in the Audio Equipment section, then you have auto- matically made a video connection at the same time, as the HDMI signal includes both digital audio and video components.
If your video display or source device is not HDMI-capable, you will need to use one of the analog video connections (composite, S- or com- ponent video), if available, as described below.
If the source device is not capable of transmit- ting its digital audio signal through the HDMI connection, then use one of the coaxial or opti- cal digital audio inputs for the source.
If a multichannel analog audio connection is required for certain lossless formats (e.g. DVD- Audio, SACD, HD-DVD or Blu-ray Disc), you may make both connections. To listen to the multi- channel disc, first select the HDMI source input, then select the 6-/8-channel analog audio inputs, and the AVR will retain the last video source you selected.
