21Analog AudioAnalog connections require two cables, one for the left channel (white)and one for the right channel (red). These two cables are often attachedto each other for most of their length. See Figure 7.Most sources that have digital audio jacks also have analog audio jacks,although some older types of sources, such as tape decks, have onlyanalog jacks. For sources that are capable of both digital and analogaudio, you may wish to make both connections.The analog audio connection is strongly recommended if you intend touse the source with the multiroom system. It’s required if you will beusing the multiroom preamp outputs with an external amplifier to poweryour remote speakers, as the AVR 347’s multiroom system is not capa-ble of converting the digital signal to analog format. It’s suggested thatyou also use the analog audio connections when using the surroundback/multiroom speaker outputs, in case another two-channel digitalaudio source is in use in the main listening area. The AVR 347 is onlycapable of processing one PCM source at a time.If you wish to record materials from DVDs or other copy-protectedsources, you may only do so using analog connections. Remember tocomply with all copyright laws, if you choose to make a copy for yourown personal use.Figure 7 – Analog AudioMultichannel analog connections are used with some high-definitionsources where the copy-protected digital content is decoded inside thesource. These types of connections are usually used with DVD-Audio,SACD, Blu-ray Disc, HD-DVD and other multichannel players. See Figure 8.However, the multichannel analog audio connection is not required forDVD-Audio players compliant with HDMI version 1.1 or better, or HD-DVDand Blu-ray Disc players that decode the digital audio internally andoutput linear PCM signals in digital format. Consult the owner’s guidefor your disc player for more information.Figure 8 – Multichannel Analog AudioHarman Kardon receivers also include a proprietary, dedicated audioconnection called “The Bridge/DMP”. If you own an iPod with a dockconnector, you may separately purchase The Bridge and connect it toThe Bridge/DMP port on the receiver. See Figure 9. Dock your iPod(not included) in The Bridge, and you may listen to your audio materialsthrough your high-performance audio system. If your iPod is photo-or video-capable, you may view still images or video materials storedon the iPod using your home theater system. You may even use theAVR 347 remote to control the iPod, with navigation messages displayedon the front panel and on a video display connected to the AVR. TheBridge outputs analog audio to the AVR 347, and it is available to themultiroom system.Figure 9 – The BridgeVideo ConnectionsAlthough some sources produce an audio signal only (e.g., CD player,tape deck), many sources output both audio and video signals (e.g.,DVD player, cable television box, HDTV tuner, satellite box, VCR, DVR).In addition to the audio connection, you will need to connect one typeof video connection for each source (never more than one at the sametime for any source).Digital VideoIf you have already connected a source device to one of the HDMIinputs as explained in the Digital Audio Connections section, then youhave automatically made a video connection at the same time, as theHDMI signal includes both digital audio and video components.If the source device is not capable of transmitting its digital audio signalthrough the HDMI connection, then use one of the coaxial or opticaldigital audio inputs for the source.If a multichannel analog audio connection is required for certain losslessformats (e.g., DVD-Audio, SACD, HD-DVD or Blu-ray Disc), you maymake both connections, but you must also make an analog videoconnection. To listen to the multichannel disc, first select the analogvideo source input, then select the 6-/8-channel analog audio inputs, andthe AVR will retain the last video source you selected other than HDMI.The AVR 347 is Simplay HD-verified for compatibility via the HDMIconnection with other Simplay HD-verified products.Figure 4 (repeated) – HDMI ConnectionAnalog VideoThere are three types of analog video connections: composite video,S-video and component video. Composite video is the basic connectionmost commonly available. The jack is usually color-coded yellow, andlooks like an analog audio jack, although it is important never to confusethe two. Do not plug a composite video cable into an analog or coaxialdigital audio jack, or vice versa. Both the chrominance (color) andluminance (intensity) components of the video signal are transmittedusing a single cable. See Figure 10.Figure 10 – Composite VideoS-video, or “separate” video, transmits the chrominance and luminancecomponents using separate wires contained within a single cable.
