2. GENERAL DESCRIPTION 

Featuring slim construction, the SR-S4 series are 2-way line array speakers containing 32 speaker elements. 

Zhe SRS4LEB-Q and SR-S4SEB-Q are intended for use in voice evacuation system applications. 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-S4LEB-Q spea-

ker is of a linear design which is ideal for long distance sound transmission applications, while the SR-S4SEB-Q 

features a curved line having a 10° vertical coverage area, and is designed to cover relatively short distance 

and voice evacuation applications.  

It is also possible to combine both the linear and curved line types to configure an array that continuously co-

vers applications ranging from short to long distances.  

3. FEATURES 

• The SR-S4 EB-Q 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 excessi-

vely 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 out-

put 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 SR-WB4WP Wall mounting bracket and SR-TB4WP Wall tilt bracket 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.) 

• The speaker can be used for high-impedance applications with the additional use of the optional MT-S0601 

matching transformer (internal mount) or MT-200 (external mounting). A matching transformer requires a sing-

le-amplifier drive.
