To use the remotecontrol, point it directly at your receiver.Set up and Maintenance of the Receiver Provide spaces for sufficient ventilation as indicated: Do not connect to the AC power cords until allconnections are completed. Do not use your set immediately after transferringit from a cold place to a warm place: there is risk ofcondensation. Do not expose your set to water and excessivelyhigh temperatures. After having disconnected your set, clean the casewith a soft cloth, or with a slightly damp leatherchamois. Never use strong solvents.Protect your Components fromOverheating Do not block ventilation holes in any component.Arrange the components so that air can circulatefreely. Do not stack components directly on top of eachother. Allow adequate ventilation when placing yourcomponents in a stand. Place an amplifier near the top shelf of the standso heated air rising from it will not affect other com-ponents. If you have a satellite receiver, you shouldplace it on the top shelf.EN310 cm/410 cm/ 410 cm/ 410 cm/45 cm/ 2FRONT SPEAKERSCENTER SPEAKERSSUB WOOFERREAR SPEAKERS(SURROUND SOUND)2 X grey/black cable for rear speakers1 X brown/blackcable for subwoofer1 X blue/black cablefor centre speaker2 X red/black cable for front speakersGetting StartedConnecting to Audio-Visual Components4PRE OUTFRONT LREAR LFRONT RREAR RINININOUTINMONITOR OUTINOUTDIGITAL INPUTDVD/CD/SATDVD/CD/SAT/TVOPTICALTVVCRCD PlayerTape DeckSAT Multi-Channel Decoder e.g. DTSto LINE OUT(Tape Deck)to LINE IN ( Tape Deck )to AUDIO OUT (CD)to VIDEO OUT (SAT)to AUDIO OUT (SAT)to S-VIDEO OUT (SAT)to S-VIDEO OUT (DVD)to AUDIO OUT(DVD)to VIDEO OUT (DVD)to AUDIO OUT (TV)to VIDEO IN (TV)to S-VIDEO IN (TV)to AUDIO OUT (VCR)to VIDEO OUT (VCR) to VIDEO IN (VCR) to AUDIO IN (VCR)to AUDIO OUTto AUDIO OUT (DVD)UNIT BACK PANELDIGITAL CONNECTIONIf you have a SAT receiver DVD player or CD player with a digital output, you can make use of an optical digital connecting cord (not supplied) or coaxial digital connecting cord (not supplied) to carry the audio portion of the signal and enjoy Dolby Digital sound quality. One optical or coaxial cable is needed for each SAT receiver, DVD player or CD player. When optical or coaxial cable is used, the analog audio cables are still needed if recording through a tape or VCR is desired. This receiver provides one optical and one coaxial digital input for the connection of your components. Please connect your components (e.g. DVD, SAT or CD) to the appropriate digital inputs and press FUNCTION and then rotate MULTIJOG to match your connection. Note: Optical and coax cables carry only the audio portion of the signal. A video connection must also be established for a SAT receiver and DVD player. S-video provides the best connection for the video portion of the signal. Composite video (yellow RCA connector) can also be used. It isimportant that the same type of cable (S-video or composite) that is connected from the Home Theater to the TV is used to connect the SAT receiver or DVD player to the Home Theater.FRONT TERMINALRemark: If you have a video camera, video game machine, or an extra VCR, connect it to VCR 2 jack at the front of the receiverDIGITAL INPUTConnect components capable of outputing Dolby Digital (e.g. DVD or SAT) or standard PCM (CD) format digital signals. Read section on Input Signal Setting under Advanced Sound Control carefully to adjust the matching input settings. If your CD player is equipped with digital optical jacks, use of optical cable is preferred. What you need is just one more optical digital connecting cord(not supplied). Plug it in the digital input jack of the receiver and select OPTICAL on the receiver setting (see details on pg 20 chapter Input Signal Setting). You can enjoy better sound quality brought to you by the optical cable. When optical cable is used, analog cables are still needed for recording to tape output. Note: This receiver has one digital optical jack only. Be sure that such connection does not prevent optical cable connection of other components (e.g. DVD & SAT) S-VIDEOIf your video component has a S-Video jack included, you can make use of it to enjoy enhanced video quality by connecting it to the relevant S-Video jack at the rear side of the receiver. One video cable is needed for each component. When S-Video cable is used, composite video (yellow RCA connector) cable must also be connected for VCR recording.Note: Before plugging in the optical cable or S-Video cable, make sure to match the shape of the plug and jack, otherwise, you will not be able to plug in completely.DVD(Decoder)Getting StartedEN5MODEL NO.: RT2280300THOMSON MULTIMEDIA INC.8FRONT SPEAKERS (8)SUBWOOFER (8)CENTER SPEAKER (8)PRE OUTFRONT LREAR LFRONT RREAR RRT2280 Rev.0 2001/01/12INININOUTINMONITOR OUTDIGITAL INPUTDVD/CD/SATDVD/CD/SAT/TVOPTICALINOUTANTENNAAMLOOPFM75Antenna and SpeakerWire ConnectionPush Speaker terminal tabdown to insert wire.Release tab to lock wire inthe terminal.NOTE: Make sure the insulationis completely removed from theends of the Antenna andspeaker wires at all connectionpoints.Digital ConnectionsRead instructions carefully when connecting compo-nents to the receiver.Digital In Jacks can accept Dolby Digital (AC-3), orPCM signals when compatible components are con-nected.Connecting the AntennasThe AM and FM antennas connect to the AM and FMterminals on the systems back panel.

In order to enjoy goodsurround effects all six speakers need to be connected to the receiverAt least two front speakers (left and right) arerequired. For better sound quality, Center speaker,rear speakers and Subwoofer should also be connected. Adding center and rear speakers willenhance surround effects. Adding a Subwoofer willincrease bass response.If you want to enjoy full range of sound effects, withsmall speakers, it is a must to use the subwoofer withthe speakers to maintain adequate bass signal.Speaker cords1 for each speaker, isneeded for connection.Twist the stripped ends ofspeaker cord about 2/3inch (15 mm).
