WARNING
CAUTION
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
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 specified 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 fitted, 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.
CAUTION
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 fire.
• 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
3
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 amplifier.
2. GENERAL DESCRIPTION
The Plane Wave Speaker features a flat 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 influence of sound reflections from the ceiling
and floor, 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 filter 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.

5.2.2. High pass filter function
[Radiation patterns]
Both types of speakers provide dispersion
characteristics shown as radiation patterns at
right.
To cut unwanted low-frequency sounds radiated
outside from the coverage area, shift the
high pass filter 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 influence on sound intelligibility.
