Installation and Connections9. Connections to a subwoofer are normallymade via a line level audio connection from theSubwoofer Output to the line-level inputof a subwoofer with a built-in amplifier. When apassive subwoofer is used, the connection firstgoes to a power amplifier, which will be con-nected to one or more subwoofer speakers. Ifyou are using a powered subwoofer that doesnot have line-level input connections, follow theinstructions furnished with the speaker for con-nection information.10. If an external multi-channel audio sourcewith 5.1 outputs such as an external digitalprocessor/decoder, DVD-Audio, SACD, Blu-ray orHD-DVD player is used, connect the outputs ofthat device to the 8-Channel Direct Inputs ,or, more easy, use the HDMI connection betweensuch a device and the AVR, or both.Video Equipment ConnectionsVideo equipment is connected in the samemanner as audio components. Again, the use ofhigh-quality interconnect cables is recommendedto preserve signal quality. To ensure best videoperformance S-Video sources should beconnected to the AVR only with their S-VideoIn/Outputs, not with their composite videoconnectors too.If you have already connected a source device toone of the HDMI inputs as explained in theAudio Equipment section, then you have auto-matically made a video connection at the sametime, as the HDMI signal includes both digitalaudio and video components.If your video display or source device is notHDMI-capable, you will need to use one of theanalog 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 HDMIconnection, then use one of the coaxial oroptical digital audio inputs for the source.If a multichannel analog audio connection isrequired for certain lossless formats (e.g. DVD-Audio, SACD, HD-DVD or Blu-ray Disc), you maymake both connections. To listen to the multi-channel disc, first select the HDMI source input,then select the 6-/8-channel analog audioinputs, and the AVR will retain the last videosource you selected.1. Connect a VCR’s audio and video Play/Outjacks to the Video 2 and Analog 4 In jacks on the rear panel. The Audio and VideoRecord/In jacks on the VCR should be connectedto the Video 2 and Analog 4 Out jacks on the AVR.2. Connect the digital audio outputs of a CD,MD or DVD player, satellite receiver, cable box orHDTV converter to the appropriate Optical orCoaxial Digital Inputs &*.NOTE: When connecting a device such as a digi-tal cable box or other set-top tuner product witha digital audio output, we recommend that youconnect both the digital and analog outputs ofthe product to your AVR. The audio input pollingfeature of the AVR will then be able to make cer-tain that you have a constant audio feed, since itwill automatically switch the audio input to theanalog jacks if the digital feed is interrupted ornot available for a particular channel.3. Connect the Composite and S-Video (if S-Video device is in use) Monitor Outputjacks on the receiver to the composite and S-Video input of your television monitor or videoprojector.4. If your DVD player and monitor both havecomponent video connections, connect the com-ponent outputs of the DVD player to the Video1 Component Video Inputs . Note thateven when component video connections areused the audio connections must still be madeto either one of the analog audio inputs or anyof the Optical or Coaxial Digital Input jacks .5. If another component video device is avail-able, connect it to the Video 2 or Video 3Component Video Input jacks *. Theaudio connections for this device should bemade to either one of the audio input jacks orany of the Optical or Coaxial Digital Inputjacks .6. If the component video inputs are used,connect the Component Video Output tothe component video inputs of your TV, projectoror display device.7. If you have a camcorder, video game or otheraudio/video device that is connected to the AVRon a temporary, rather than permanent basis,connect the audio, video and digital audio out-puts of that device to the Front Panel Inputs&*(.ENGLISHINSTALLATION AND CONNECTIONS 17
