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.

2. GENERAL DESCRIPTION
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.
3. FEATURES
•
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)
4. ABOUT THE INPUT OVERLOAD PROTECTION CIRCUITRY
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.
