21、w SuggestionsWe recommend that you do not operate 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

22、 indication of the overall loudness level of thespeakers.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 C

23、D,or switchinginputs to AM or FM operation.Excessively 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.Subwoofer Level ControlLFE InputLine

27、ersystem,make sure all speakers are set to “Small” . When using thesystem in a Dolby Pro Logichome theater system,make sure thereceivers center channel mode is set to “Normal. ”Some Dolby Digital-equipped receivers/processors offer differentsetup options for each source or surround mode (e.g.,CD-ste

28、reo,videotape,Dolby Digital,Pro Logic).In each case,follow yourequipments instructions to ensure that the subwoofer output isturned on and that the speakers are set to “Small”in each mode.If your receiver has adjustable crossover settings,we recommendthe subwoofer crossover be set between 100Hz and

29、120Hz.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 1to the“MIN”position.Turn on the subwoofer by pressing the Power Switch 4on the rear panel.Turn on your entire audio system and start a CD or movie

30、 soundtrack at a moderate level.Auto On/StandbyWith the Power Switch 4in the ON position,the LED on the backwill remain lit in green or red to indicate the ON/STANDBY mode ofthe subwoofer.RED = STANDBY (No signal detected,Amp Off)GREEN = ON (Signal detected,Amp On)The subwoofer will automatically en

31、ter the Standby 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 4can be left on.You may turn off the Power Switch 4for extendedperiods of nonoperation,e.g.,

32、when you are away on vacation.Adjust LevelTurn the Subwoofer Level Control 1up about halfway.If no soundemanates from the subwoofer,check the AC-line cord and inputcables.Are the connectors on the cables making proper contact? Is the AC plug connected to a “live”receptacle? Has the PowerSwitch 4been

33、 pressed to the “On”position? Once you haveconfirmed that the subwoofer is active,proceed by playing a CD 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 1until you obtain a pleas

34、ing 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 of bass.This is not ent

35、irely true.A subwoofer is there to enhance bass,extending the response of the entire system so the bass can be felt as well as heard.However,overall balancemust be maintained or the music will not sound natural.Anexperienced listener will set the volume of the subwoofer so itsimpact on bass response

36、 is always there but never obtrusive.Final PositioningAfter correctly connecting the TSS-500 system and verifying that both the subwoofer and all satellite speakers are playing,it is time to optimize the system for your particular listeningroom.Earlier,you placed the subwoofer in its general locatio

37、n.Finding the exact location for optimum performance sometimesonly involves 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.MAINTENANCE ANDSERVICEThe satellite and subwoofer enclosu

38、res 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 conditionsand other factors,but once per year is the

39、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 the loud-speaker.If the problem appears in the opposi

40、te speaker,thecause is in another component or cable.In the event that yourTSS-500 ever needs service,contact your local Infinity dealer orvisit for a service center near you.TSS-500 OM 1/20/06 2:45 PM Page 107TSS-Sub500 8TSS-Sub500 Test Set Up and Procedure Equipment needed: Function/signal generat

41、or/sweep generator Integrated Amplifier Multimeter Speaker cables General Unit Function (UUT = Unit Under Test) 1) From the signal generator, connect one line level (RCA) cable to the Subwoofer Line Level Input jacks L/R on the UUT. Use a Y-cable from a mono source if necessary to connect to both in

42、puts. Do not connect to the single LFE input. 2) On the front of the unit, turn the LEVEL control full counterclockwise. 3) Turn on generator, adjust to 100mV, 50 Hz. 4) Plug in UUT; turn the power switch ON. LED should be Red. Turn LEVEL control full clockwise (MAX) 5) LED should now be Green; imme

43、diate bass response should be heard and felt from port tube opening. 6) Turn off generator, turn LEVEL control fully counterclockwise, disconnect RCA cable. Sweep Function 1) Follow steps 3-6 above, using a sweep generator as a signal source. 2) Sweep generator from 20Hz to 300Hz. Listen to the cabi

44、net and drivers for any rattles, clicks, buzzes or any other noises. If any unusual noises are heard, remove woofers and test. Driver Function 1) Remove woofer from cabinet; detach + and - wire clips. 2) Check DC resistance of woofer; it should be 3.3 ohms 10% 3) Connect a pair of speaker cables to

45、driver terminals. Cables should be connected to an integrated amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V. 4) Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises. 9TSS-Sub500 10TSS-Sub500 TSS
