1. SAFETY PRECAUTIONS
• Beforeinstallationoruse,besureto carefullyread alltheinstructionsinthissection forcorrect andsafe
operation.
• Besuretofollowalltheprecautionaryinstructionsinthissection,whichcontainimportantwarningsand/or
cautions regarding safety.
• Afterreading,keepthismanualhandyforfuturereference.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual rst and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
resultinmoderateorminorpersonalinjury,and/orpropertydamage.
WARNING
CAUTION
When Installing the Unit
• Referallinstallationworktothedealerfromwhom
the speaker was purchased. Installation requires
extensive technical knowledge and experience.
The speaker may fall off if incorrectly installed,
resulting in possible personal injury.
• Installtheunitonlyinalocationthatcanstructurally
support the weight of the unit and the mounting
bracket. Doing otherwise may result in the unit
falling down and causing personal injury and/or
property damage.
• When installing the unit in the snowy area, take
appropriate measures to prevent snow from lying
on the unit. If the snow lies on the unit, the unit may
fall, causing personal injuries.
• Owingtotheunit’ssizeandweight,besurethatat
least two persons are available to install the unit.
Failure to do so could result in personal injury.
• Donotuseothermethodsthanspeciedtomount
the bracket. Extreme force is applied to the unit and
the unit could fall off, possibly resulting in personal
injuries.
• Fit the unit with a safety wire to prevent it from
falling.Ifnottted,theunitcouldfalloff,resultingin
personal injury.
• Use nuts and bolts that are appropriate for the
ceiling’s or wall’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.
• Be sure to use the supplied mounting bracket
in combination. Doing otherwise may cause the
speaker to fall, resulting in personal injury.
• Do not mount the unit in locations exposed to
constant vibration. The mounting bracket can be
damaged by excessive vibration, potentially causing
the unit to fall, which could result in personal injury
• Avoidinstallingthespeakerinlocationsclosetothe
seashore or in indoor swimming facilities that are
not well ventilated. In such locations, the bracket
may be vulnerable to corrosion, eventually allowing
the speaker to fall resulting in personal injury.
When Installing the Unit
• Avoid touching the unit’s sharp metal edge to
prevent injury.
When the Unit is in Use
• Donot operatetheunit for an extended periodof
time with the sound distorting. Doing so may cause
theunittoheat,resultinginare.
• Donotstandorsiton,norhangdownfromtheunit
as this may cause it to fall down or drop, resulting in
personalinjuryand/orpropertydamage.
• Havetheunitcheckedperiodicallybytheshopfrom
where it was purchased. Failure to do so may result

in corrosion or damage to the unit or its mounting
bracket that could cause the unit to fall, possibly
causing personal injury.
· Never connect a 170 Ω speaker lead to high
impedance 100 V line, as this will damage the
speakerandamplier.
2. GENERAL DESCRIPTION
ThePlaneWaveSpeakerfeaturesaatspeakersystemequippedwithplanewaveunits,realizinganarrow
directivity pattern by radiating plane wave sound.
Since the Plane Wave Speaker can deliver sound output toward a limited target area, it is suited for use
in locations such as station platforms and escalator areas that require information announcements to be
broadcast, and in such spaces as museums and art galleries where the reverberation time is long.
The Plane Wave Speaker lineup includes the following 8 models.
• PW-1230DBandPW-1230DW(compactdouble-sidedradiationtype)
• PW-1230SBandPW-1230SW(compactsingle-sidedradiationtype)
• PW-1430DBandPW-1430DW(largedouble-sidedradiationtype)
• PW-1430SBandPW-1430SW(largesingle-sidedradiationtype)
Note: The rightmost letter of each model number indicates color: “B” for black and “W” for light ivory.
A double-sided radiation type radiates sound both backward and forward, while a single-sided radiation type
radiates sound forward only.
The most appropriate model can be selected depending on the condition of installation location and application.
3. FEATURES
• TwotypesofPlaneWaveSpeakersavailable:Acompacttype(PW-1230series)consistingof2planewave
unitsandalargetype(PW-1430series)consistingof4planewaveunits.
• Sound dispersion range is narrow in both horizontal and vertical directions, enabling sound output to be
deliveredtowardalimitedtargetarea.Lesssusceptibletotheinuenceofsoundreectionsfromtheceiling
andoor,allowingclearsoundtobedeliveredeveninspaceswithpooracousticconditionssuchaslong
reverberation time.
• Abuilt-inbeamtiltingfunctionfortiltingsoundradiationdirectionabout5°downwardfromthehorizontal
• Abuilt-inhighpasslterforcuttinglowfrequencies
• ComplianttoIPX4(IEC60529)*waterprotectionrating
• Stainlesssteel-mademetalpartsoftheplanewaveunitandthespeakerenclosure
* The performance of the unit is not harmfully affected even if water is splashed upon the unit from every
direction.

5. SETTING
5.1. Impedance Setting
Referringtothetablebelow,usethespeakerleadscorrespondingtoyourdesiredimpedance(ratedinput)for
connectiontotheamplier.
The green lead is for high impedance 70 V line use only.
Never use it on high impedance 100 V line since the amplifier or
speaker itself may be damaged.
CAUTION
Notes
•Besuretoinsulateunusedleadssoasnottoshort-circuit.
•Waterproofthecablejointbywrappinginsulatingtapearounditwhenthejoint
may be exposed to rain or water.
5.2. Beam Tilting and High Pass Filter Settings
To change the setting, loosen 2 screws on the bottom surface of the speaker, open the switch cover, then
change the setting using the toggle switch.

5.2.2. High pass filter function
Both types of speakers provide dispersion
characteristics shown as radiation patterns at

To cut unwanted low-frequency sounds radiated
outside from the coverage area, shift the
high pass lter switch to the “ON” position.
Frequenciesbelow450Hzarecutat−12dB/oct.
In this case, low-frequency sounds in the
coverage area are cut as well, however, this will
havelittleinuenceonsoundintelligibility.
These ratiation patterns are viewed from above the speakers.

6. INSTALLATION PRECAUTIONS
ThePlaneWaveSpeakerfeaturessplash-proofconstruction(IPX4waterprotection)andcanbeinstalledunder
eaves not directly exposed to rain or snow. But the speaker installation orientation is limited as follows.
Be sure to follow the instructions below. Failure to do so may cause damage to the speaker.

7. INSTALLATION
Be sure to observe the following instructions.
Failure to do so may cause the unit to fall, possibly resulting in personal
injury.
•Useboltsandnutsthatareappropriateforthematerialandstructure
at the installation location.
•Securelytightenallbolts.
•Besuretouseatleast4boltstosecurethemountingbrackettothe
installation location.
