OPERATION 13OPERATIONMove the Master Power Switch ‚(marked Power) to the “•” (On) position.The SUB-TS18 subwoofer will automaticallyturn itself on or go into Standby mode,depending on whether or not a signal isbeing sent to it by your receiver or surroundprocessor, and provided that the Audio-Sense On/Off Switch ¢ is moved downso that it is in the AUTO position.When your receiver or amplifier is off, or isnot sending program material to the sub-woofer, the subwoofer will be in Standbymode and the LED indicator on the topof the subwoofer will turn amber. When thesubwoofer senses an audio signal, it will auto-matically turn itself on and the LED indicatorwill turn blue. If the subwoofer does notsense a signal after approximately 20 minutes,it will automatically go into Standby mode.When the Audio-Sense On/Off Switch ¢is switched to the ON position, the sub-woofer will remain on, whether or not pro-gram material is playing, and the LED indica-tor will remain lit blue.If your receiver, processor or amplifier isequipped with a compatible trigger output,you may connect it to the SUB-TS18’sExternal Trigger Input £. When you turnon your component, if you have set it up cor-rectly, it will send an electrical trigger signalto the SUB-TS18, which will cause thesubwoofer to turn itself on, even when theAudio-Sense On/Off Switch ¢ has beenplaced in the AUTO position and no audiosignal is detected.The trigger signal must be between 3 and 30volts, although it may be an AC or DC signal,and an AC signal may be 50Hz or 60Hz.If you’ll be away from home for an extendedperiod of time, or if the subwoofer will not beused, switch the Master Power Switch ‚to the OFF position.VolumeVolume can be adjusted using the Sub-woofer-Level Control ¡, as shown.Turn the control knob clockwise toincrease the volume of the subwoofer,and counterclockwise to decrease thesubwoofer’s volume.Additional Bass AdjustmentsIn addition to the volume adjustments describedpreviously, the SUB-TS18 subwoofer includesa Phase Switch ∞ and a Filter Switch™ that can be used to adjust the bassresponse to suit your listening environmentor taste.In most situations, the Phase Switch ∞should be left in the NORMAL position.If you suspect that the subwoofer is playingout of phase with the other speakers, whichwould tend to diminish bass response, tryplacing this switch in the REVERSEposition. There is no harm in experimenting,and you may return the switch to theNORMAL position at any time. If yourearrange your room and reposition thespeakers, it would be a good idea to checkwhether they are in phase by flipping thisswitch.The High-Cut (Low-Pass) Filter Switch™ limits the frequencies of the audio signalinputted to the subwoofer to the low fre-quencies that the subwoofer reproducesbest. This allows the subwoofer to performmore efficiently, and with superior bassreproduction, minimizing distortion that mightoccur if the subwoofer attempted to repro-duce higher frequencies. This switch shouldbe left in the ON position, except:1. When the SUB Input § is being used,in which case it has no effect, or2. When the Speaker-Level Inputs ªor the Line-Level Full-Range Inputs¶ are being used with a crossover orfilter aboard the receiver or processor.In these two circumstances, place the switchin the OFF position.MIN MAXSubwooferLevelMIN MAXSubwooferLevel
