2. GENERAL DESCRIPTION
The line array speaker features slim 84 mm (3.3")-wide construction incorporating high-quality 7 cm (2.8") full-
range speaker units. The internal speaker units are vertically arrayed in close proximity to form an extended
sound source line, minimizing distance attenuation and realizing a uniform sound pressure coverage area.
The line array speaker lineup includes the following four models:
• SR-H2L (Short and Linear type)
• SR-H2S (Short and Curved type)
• SR-H3L (Long and Linear type)
• SR-H3S (Long and Curved type)
The linear version provides excellent sound transmission distance. The curved version provides a 20° vertical
directional angle that is designed for relatively short range coverage. The most appropriate model can be
selected to match installation location and application.
3. FEATURES
• The short type (SR-H2L and SR-H2S) is constructed of 9 speaker units, while the long type (SR-H3L and
SR-H3S) is constructed of 16 speaker units.
• Each speaker employs high-quality, heavy-duty 7cm (2.8") full-range drivers offering superb coverage in
high frequencies.
• Unique front grille construction effectively widens the full-range drivers high frequency horizontal directivity.
• Since the linear sound source effect prevents acoustical energy from attenuating even at longer distances,
the line array speaker provides advantages compared with normal types of speakers in its ability to project
sound long distances. This realizes less difference in sound volume between areas close and far from the
speaker, for a more uniform sound field.
• Since the speaker's vertical sound dispersion is focused, sound is only directed at the target area.
The line array speaker (when correctly positioned) is not influenced by sound reflection from ceiling or floor
surfaces, and can provide clear sounds even in spaces affected by long reverberation times or other poor
acoustic conditions.
• Since the attenuation of sound pressure is small even far away from the speaker, the volume is not
excessively loud in the area near the speaker. This helps suppress feedback (improving microphone
amplification gain).
• Two linear types can be linked to improve sound transmission distance and widen the vertical coverage
area.
• The use of optional mounting brackets permits the speaker to be installed in the most appropriate location
for its intended use.
· When mounting flat against a wall: SR-WB3 Wall Mounting Bracket
· When mounting on a wall at some horizontal and vertical angles: SR-TB3 Wall Tilt Bracket
· When suspending from a ceiling: SR-FB3 Flying Bracket
· When mounting on a speaker stand: SR-SA3 Stand Adapter and ST-33B Speaker Stand
Note: For installation instructions, refer to the instruction manuals enclosed with each mounting bracket.
• The speakers can be used for high-impedance applications with the installation of the optional MT-S0301
Matching Transformer (Rated input: 30 W).
• Removable input connector facilitates connection and wiring
