to do so could result in personal injury.
• Do not use other methods than specified to install the speaker. Extreme force is applied to the unit and the
unit could fall off, possibly resulting in personal injuries.
• 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.
• Use the specified mounting bracket in combination. Doing otherwise may cause the unit or component to fall
off, 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.

CAUTION
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
When Installing the Unit
• Avoid placing the unit in a doorway or other high traffic area as people may trip on the equipment and cords,
or be injured by falling objects.
• Avoid touching the unit's sharp metal edge to prevent injury.
• When installing the speaker at head height, attach the optional SR-PP4 Protection Pad to the bottom of the
speaker. Failure to do so may cause injury if people hit their heads directly against the speaker.
When the Unit is in Use
• Do not operate the unit for an extended period of time with the sound distorting. This is an indication of a
malfunction, which in turn can cause heat to generate and result 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.

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-S4LWP speaker is of a linear design which is ideal for long distance sound transmission applications,
while the SR-S4SWP 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 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. (Single-amplifier drive only)

4. INSTALLATION PRECAUTION
CAUTION
When permanently installing the speaker outdoors, inspect it periodically.
Damage or corrosion of the speaker or mounting hardware could cause
the speaker to fall, possibly resulting in personal injury.
• The SR-S4LWP and SR-S4SWP speakers feature water protection construction (IPX4), however it is
recommended that they be installed under roofs, eaves, or in other locations not directly exposed to rain or
snow.
• Take care not to install the speaker upside-down relative to the "UP" mark affixed to the speaker's rear
panel.
• Do not install the speaker horizontally.
• The downward angle must be within 45° for the SR-S4LWP and within 30° for the SR-S4SWP.

5. COVERAGE AREA
The line array speaker radiates a sound only within a limited range.
Since sound is reduced in areas that are outside the range, take care that the listening area is sufficiently
covered when installing the speaker.
