2. GENERAL DESCRIPTION
Featuring slim construction, the SR-S4 series are 2-way line array speakers containing 32 speaker elements.
The sound source speaker elements are vertically arranged in close proximity to each other, and form a
continuous linear sound source, achieving uniform sound pressure with less attenuation due to distance.
The SR-S4L speaker is of a linear design which is ideal for long distance sound transmission applications,
while the SR-S4S features a curved line having a 10° vertical coverage area, and is designed to cover
relatively short distance applications.
It is also possible to combine both the linear and curved line types to configure an array that continuously
covers applications ranging from short to long distances.
3. FEATURES
• The SR-S4 series is a 2-way line array speaker having eight 10 cm woofers for low-frequency output, and 24
small tweeters for high-frequency sound output. Both the woofers and tweeters are arranged in the front and
rear on the same axis, providing a symmetrical, uniform coverage area.
• Since the linear sound source effect prevents energy from attenuating even at longer distances, the line
array speaker compares favorably 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 suppressed, sound is only directed at the target area. The
speaker's construction 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 safety amplification
gain).
• By joining 2 or 3 speakers, a longer sound source can be configured, making it possible to project sound
output farther and at larger volumes.
• The speaker has a built-in network circuit for a single amplifier drive. Changing the internal connector
position enables bi-amplifier drive that provides a higher quality sound output.
• The use of optional mounting brackets* permits the speaker to be installed in the most appropriate position
for its intended use. (Details of the installation procedures are described in the installation manual enclosed
with each bracket.)
* SR-WB4 Wall mounting bracket, SR-TB4 Wall tilt bracket, SR-FB4 Flying bracket, SR-SA4 Stand adapter,
and SR-FS4 Floor stand.
• The speaker can be used for high-impedance applications with the additional use of the optional MT-S0601
Matching transformer. (Single-amplifier drive only)
