Before installation and use, be sure to carefully read all the instruction in this section for correct and safe
operation.
Indicates a potentially hazardous situation which, if mishandled,
could result in death or serious personal injury.
When Installing the Unit
• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing
so may result in the unit falling down and causing personal injury and/or property damage.
• Refer all installation work to the dealer from whom the speaker was purchased. Installation requires extensive
technical knowledge and experience. The speaker may fall off if incorrectly installed, resulting in possible
personal injury.
• Flying Precautions
Be sure to follow the instructions below. Otherwise, the suspension wires or belts may be off or snap and the
speaker may fall off, causing personal injury.
vCheck to confirm that the suspension wires and belts are strong enough to withstand the speaker load.
vThe connectors of the suspension wires and belts must be securely linked with those of the speaker.
vAll parts and components (such as enclosures, metal pieces, and screws) must be free from any
deformation, crack, and corrosion.
vBe sure to use screws supplied with the optional flying hardware when installing the speaker using such
hardware.
• Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket.
Doing otherwise may result in the unit falling down and causing personal injury and/or property damage.
• Owing to the unit's size and weight, be sure that at least two persons are available to install the unit. Failure 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 injury.
• 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.
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 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.
• Have the unit checked periodically by the shop from where it was purchased. Failure to do so may result in
corrosion or damage to the unit or its mounting bracket that could cause the unit to fall, possibly causing
personal injury

3. FEATURES
4. ABOUT THE INPUT OVERLOAD PROTECTION CIRCUITRY
Featuring slim construction, the TZ-S240W-AS are 2-way 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 TZ-S240W-AS
speaker is of a special design which is ideal for long distance sound transmission applications.
• The TZ-S240W-AS is a 2-way slim 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, providing uniform coverage area.
• Since the linear sound source effect prevents energy from attenuating even at longer distances, the slim 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 speakers, a longer sound source can be configured, making it possible to project sound output
farther and at larger volumes.
• 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)
The speaker system features internal input overload protection circuitry. If an extremely high input level is fed to the
unit, the protection circuitry automatically cuts off the signal to the speaker. A drastic reduction in sound volume of
speaker indicates that the protection circuitry has been enabled.
In such cases, simply reduce the amplifier volume. The protection circuitry will automatically reset in approximately
10 seconds.After reset, try to maintain the volume at a level slightly lower than before.
Caution:
This protection circuitry does not completely protect the unit against extremely high input power levels. Depending
on the type or duration of excessive power input, the protection circuitry might not be enabled, resulting in damage
to the speaker element. Also, if the excessive power input continues for a long period of time, the circuitry may not
be capable of resetting to its original condition.
Use the system with care so that the speakers are not exposed to excessive power input.

9. JOINING SPEAKERS
Joining slim array speakers configures a longer linear sound source, permitting richer low-frequency sound
reproduction as well as transmission of higher sound output over a longer distance.
To join speakers, use the optional SR-EP4 Extension Plate.
[Joining procedure]
Step 1. Remove the (M5 oval-head) screws on both sides of the speaker. The removed screws are no longer
used.
Step 2. Join 2 speakers using the SR-EP4 Extension plate. Fix the plate to the speaker using the hex head bolts
supplied with the SR-EP4.

5. COVERAGE AREA
The 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.
