Optimus PW-1230DB The Optimus PW-1230DB plane wave speaker is equipped with two plane wave units, delivering sound toward a limited target area. This reduces the influence of reflections from the ceiling and floor, enabling clear sound delivery even in spaces with long reverberation time, such as station platforms, museums, and art galleries. The built-in beam tilting function allows for downward adjustment of the sound radiation direction by about 5 degrees from the horizontal, while the high pass filter cuts low frequencies.

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. 4 4.

Never use it on high impedance 100 V line since the amplifier or speaker itself may be damaged. 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. These switches are factory-preset as follows. Switch name BEAM TILTING HIGH PASS FILTER BEAM TILTING (VERTICAL BEAM ANGLE) DOWNWARD Switch cover Speaker body (bottom side) 6 FLAT Setting FLAT OFF HIGH PASS FILTER (450Hz -12dB/oct) ON OFF 5.2.1. Beam tilting function Shifting the beam tilting switch to “DOWNWARD” causes the sound radiation to be directed about 5° downward from the horizontal. Switch setting FLAT DOWNWARD Radiation direction 0° 5° Downward [When shifted to “FLAT”] Central axis of sound radiation [When shifted to “DOWNWARD”] 5° Central axis of n sound radiatio Area where sound is especially intelligible 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. • Double-sided type • Single-sided type Coverage area Coverage area Speaker Speaker Legend : High-frequency sound Coverage area : Low-frequency sound These ratiation patterns are viewed from above the speakers. 7 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. • Install the speaker so that its bottom surface is positioned downward. Five air vents are provided in the bottom surface.
