18、ate your speakers orsubwoofer with the bass,treble and loudness controls set to full boost.This will place undue strain on your electronics andspeakers and could damage them.The volume control setting on your processor/preamp or receiveris not a specific indication of the overall loudness level of t

19、hespeakers.The only important consideration is the loudness level atwhich the system can be played,regardless of where the volumecontrol is set.Always turn down the volume control setting on your processor/preamp or receiver when changing a cassette or CD,or switchinginputs to AM or FM operation.Exc

20、essively loud transients (clicks orpopping sounds) can damage the satellite speakers and possiblythe subwoofer.Important!Whenever changing cables,pulling plugs,etc.,ALWAYS TURN OFFALL EQUIPMENT,including the subwoofer.SUBWOOFERCONTROLSRear Panel?Subwoofer-Level Control ?LFE/Normal Switch?Phase Switc

When using theTSS-1100 in a Dolby Pro Logic* home theater system,make surethe receivers center channel mode is set to

26、 “Normal.”Some Dolby Digital-equipped receivers/processors offer differentsetup options for each source or surround mode,e.g.,CD-stereo,videotape,Dolby,Pro Logic.In each case,follow your equipmentsinstructions to ensure that the subwoofer output is turned on andthat the speakers are set to “Small”in

27、 each mode.Power OnPlug your subwoofersAC cord into a wall outlet.Do not use theoutlets on the back of the receiver.Initially set the Subwoofer Level Control ?to the“MIN”position.Turn on the subwoofer by pressing the Power Switch ? on the rear panel.Turn on your entire audio system and start a CD or

28、 movie sound-track at a moderate level.Auto On/Stand-ByWith the Power Switch ?in the ON position,the LED on the frontpanel will remain lit in red or green to indicate the On/Stand-Bymode of the subwoofer.RED = STAND-BY (No signal detected,Amp Off)GREEN = ON (Signal detected,Amp On)The subwoofer will

29、 automatically enter the Stand-By mode afterapproximately 10 minutes when no signal is detected from yoursystem.The subwoofer will then power ON instantly when a signalis detected.During periods of normal use,the Power Switch ?can be left on.You may turn off the Power Switch ?for extendedperiods of

30、nonoperation,e.g.,when you are away on vacation.Adjust LevelTurn the Subwoofer Level Control ?up about half way.If nosound emanates from the subwoofer,check the AC-line cord andinput cables.Are the connectors on the cables making propercontact? Is the AC plug connected to a “live”receptacle? Has the

31、Power Switch ?been pressed to the “On”position? Once youhave confirmed that the subwoofer is active,proceed by playing aCD or DVD.Use a selection that has ample bass information.Set the overall volume control of the receiver/processor to acomfortable level.Adjust the Subwoofer Level Control ?until y

32、ou obtain a pleasing blend of bass.Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range.Many users have a tendency to set the subwoofer volume too loud,adhering to the belief that a subwoofer is there to produce lots ofbass

33、.This is not entirely true.A subwoofer is there to enhancebass,extending the response of the entire system so the bass can be felt as well as heard.However,overall balance must be maintained or the music will not sound natural.An experiencedlistener will set the volume of the subwoofer so its impact

34、 onbass response is always there but never obtrusive.Crossover AdjustmentThe Crossover Frequency Control ? determines the highestfrequency at which the subwoofer reproduces sounds.For the TSS-1100,it is recommended that this control be set at 120Hz(approximately the 3 oclock position).NOTE: This con

35、trol will have no effect if the LFE/Normal Switch? is set to LFE.If you have a Dolby Digital or DTS receiver/processor,the Low-Pass Frequency is set by the receiver/processor.Set the LFE/Normal Switch ? on the subwoofer toLFE.Consult your owners manual to learn how to view or changethis setting.A se

36、tting of 120Hz 150Hz is recommended.Phase ControlThe Phase Switch ? determines whether the subwooferspeakers piston-like action moves in and out with the mainspeakers,0,or opposite the main speakers,180.Proper phaseadjustment depends on several variables such as room size,subwoofer placement and lis

37、tener position.Adjust the phaseswitch to maximize bass output at the listening position.Final PositioningAfter correctly connecting the TSS-1100 system and verifyingthat both the subwoofer and all satellite speakers are playing,itis time to optimize the system for your particular listening room.Earl

38、ier,you placed the subwoofer in its general location.Findingthe exact location for optimum performance sometimes onlyinvolves moving the speakers up to a few inches in anydirection.We urge you,therefore,to experiment with placement,if possible,until your speakers deliver their full potential.MAINTEN

39、ANCE ANDSERVICEThe satellite and subwoofer enclosures may be cleaned using asoft cloth to remove fingerprints or to wipe off dust.All wiring connections should be inspected and cleaned orremade periodically.The frequency of maintenance depends onthe metals involved in the connections,atmospheric con

40、ditions,and other factors,but once per year is the minimum.If a problem occurs,make sure that all connections are properlymade and clean.If a problem exists in one loudspeaker,reversethe connection wires to the left and right system.If the problemremains in the same speaker,then the fault is with th

41、e loud-speaker.If the problem appears in the opposite speaker,thecause is in another component or cable.In the event that yourTSS-1100 ever needs service,contact your local Infinity dealer or Infinity directly at 516.674.4INF (USA only) for a service center near you.TSS-1100 OM 12/16/03 3:21 PM Page

Work evenly around the perimeter until t

43、he grill w/ gasket can be removed. 2) Remove the (6) Phillips screws holding the trim ring to the cabinet. 3) Remove the (6) Phillips screws holding the woofer to the cabinet.
