WARNING
CAUTION
WARNING
• Referallinstallationworktothedealerfromwhom
the speaker was purchased. Installation for ying
requires extensive technical knowledge and
experience. The speaker may fall off if incorrectly
installed,resultinginpossiblepersonalinjury.
• FlyingPrecautions
Besuretofollowtheinstructionsbelow.Otherwise,
the suspension wires or belts may be off or snap
and the speaker may fall off, causing personal
injury.
· Check toconrm that the suspension wires and
beltsarestrongenoughtowithstandthespeaker
load.
· Theconnectorsofthesuspensionwiresandbelts
mustbesecurelylinkedwiththoseofthespeaker.
· All parts and components (such as enclosures,
metalpieces,andscrews)mustbefreefromany
deformation,crack,andcorrosion.
· Besuretousescrewssuppliedwiththeoptional
yinghardwarewheninstallingthespeakerusing
suchhardware.
• Install the speaker only in a location that can
structurallysupporttheweightofthespeakerand
the mounting bracket. Doing otherwise may result
in thespeaker falling down and causing personal
injuryand/orpropertydamage.
• Since thespeakerisdesignedforin-dooruse,do
notinstallitoutdoors.Ifinstalledoutdoors,theaging
of parts causes the speaker to fall off, resulting in
personalinjury.
• Owing to the speaker's size and weight, be sure
that at least two persons are available to install the
speaker. Failure to do so couldresult inpersonal
injury.
• Donotuseothermethodsthanspeciedtoinstall
thespeaker.Extremeforceisappliedtothespeaker
and itcouldfall off, possibly resulting inpersonal
injuries.
• Use nuts and bolts that are appropriate for the
ceiling'sstructureandcomposition.Failuretodoso
may cause the speaker to fall, resulting in material
damageandpossiblepersonalinjury.
• Tighten each nut and bolt securely. Ensure that
the bracket has no loose joints after installation
to prevent accidents that could result in personal
injury.
• Do not mount the speaker in locations exposed
to constant vibration. The mounting bracket can
be damaged by excessive vibration, potentially
causing the speaker to fall, which could result in
personalinjury.
• Avoid installing the speaker in indoor swimming
facilities that are not well ventilated. In such
locations,themountinghardwaremaybevulnerable
to corrosion, eventually allowing the speaker to fall
resultinginpersonalinjury.
• Avoidtouchingthefrontpunchednet'ssharpmetal
edgetopreventinjury.
• Toavoidelectricshocks,besuretoswitchoffthe
amplier'spowerwhenconnectingthespeaker.
• Donotplaceheavyobjectsonthespeakerasthis
may cause it to fall or break which may result in
personalinjuryand/orpropertydamage.Inaddition,
theobjectitselfmayfalloffandcauseinjuryand/or
damage.
• Do not operate the speaker for an extended
periodoftimewiththesounddistorting.Thisisan

7. LEVEL BALANCE AND POLARITY
WhenusingtheFB-150seriesinconjunctionwithfullrangespeakers(suchasTOA'sHX-7SeriesSpeakerSystem),adjust
thelevelbalanceandpolarityforeachspeakerindependentlydependingontheinstallationsite.
[Level balance adjustment]
Increaseordecreasethelevelofthesubwoofer(orfullrangespeaker)asappropriatetothenumberofunitsandinstallation
conditions.
[Polarity adjustment]
• Ifthesubwooferandfullrangespeakersareinphaseintheircrossoverband,thenacousticenergyisadded;however,
acousticenergyissubtractedifthetwoareinreversedphase.Sincethephasecharacteristicsofboththesubwooferand
fullrangespeakerchangecontinuouslydependingonthefrequency,itmaynotbeidealtofollowthesubwoofer'spolarity
instructions when connecting it.
• Comparethedegreetowhichacousticenergyincreasesbyswitchingthepolarityoftheconnectionatthesubwoofer
(from positive tonegative and from negative to positive). Choose the way of connection that resultsin the greatest
increase in acoustic energy. To match the polarity correctly, make actual measurements of acoustic energy using a real
timespectrumanalyzer.
