Well-Focused Sound Enhancement

Among TOA’s wide range of sound reinforcement products, Line Array
Speaker Systems play an important role in providing high quality audio for
various large and medium-sized venues ranging from houses of worship,
conference centers to railway stations and airports or venues with highly
reective interior surfaces.

Versatile Operational
& Installation Features

TOA’s Type S Line Array Speaker Systems are designed for permanent installations and
are available in slim, tower configurations. It limits vertical sound dispersion in order to
focus directivity at the targeted listening area.

The SR-S4L and SR-S4S are both 2-way line array speakers, each containing 32 speaker
elements - 8 x 10cm woofers and 24 high frequency drivers. Driver units are installed
vertically with minimal space between units in order to create a continuous linear sound
source. This enables delivering of a uniform sound pressure that resists attenuation with
distance.

Bi-amp or Single Amp Drive

Bi-amping setting possible for Type S speakers by making a
simple internal wiring change.

(*factory pre-set is for single amplifier driving)

For optimal bi-amping, a digital signal processor can be
employed to set crossover frequency points.

High Impedance Compatibility

High impedance applications make possible by using the
optional MT-S0601 matching transformer.

(This option is only possible when driving the speaker with single

amplifier.)

Sound Dispersion Characteristics

SR-S4L speaker features a linear design tailored for
distance sound transmission applications.
SR-S4S designed with a gentle curved line of a 10
coverage area. Ideal for coverage over a shorter distance.

° vertical

Multi-Speaker Array-Configurable

Combine long and short throw speakers to realize a
versatile speaker array that performs equally well in
terms of sound cover and dispersion over short and long
distances.
Less difference in sound level is preceived whether close to
or somewhat distant from the speakers, providing a uniform
response.
Adding additional long throw boxes provides a longer
sound source that can deliver greater output as well as
sound projection for a greater distance

Reflection-Free & Feedback Resistant

The construction and characteristics of the speakers make
them resistant to floor and ceiling originating reflections.
This enhances clarity even in reverberant spaces and other
problematic environments.
Design of the speakers make them highly resistant to
annoying feedback because volume levels are not
extraordinarily high even close to the speakers and makes
setting gain levels easier.

Slim & Stylish

Type H Line Array Speakers come with sound
enhancement benefits such as clear sound,
excellent directionality of focus on the
listening area, and transmission of clear even
sound over a distance, thanks to a low degree
of sound attenuation.

These speakers are well-suited for medium-sized
speech oriented applications where clear, uniformly
dispersed sound that is audible at a distance is
essential. such as conference centers, houses of
worship and railway stations, or venues with highly
reflective interior surfaces.

The Type H consists of four models, in short or
long lengths and straight or curved variations. The
short models contain 9 vertically connected 7-cm
(2.8”) fully range speaker units, while the taller long
models come with 16 speaker units. Both lengths
work to provide high quality sound even when an
equalizer is not used.

The speaker units come in a slim energy-efficient
and cost-effective design, with a body that is
narrower than earlier versions, so they are
well-suited to a wide range of venue interiors.

84mm

Outstanding Sound Quality

Sync-Drive (Synchronous Nexus Control)
technology keeps the audio in phase with
its sources at the speakers to create an
ideal linear sound source.
Line array configuration of speakers works to produce clear
sound with reduced attenuation over distance.
Speakers are reflection-free and feedback resistant.
Unique aperture front grille structure enhances the
horizontal frequency vs. beam width response for more
focused horizontal dispersion.
Designed for optimally precise directivity of sound,
especially vertical directivity. Audio dispersion can be
more accurately focused at the targeted area.
Curved speaker models reply on a hyper-clothoid concept
curved array that ensures improved vertical dispersion.

Application Versatility

Four available models, enabling extensive customization of
the listening area..
Most applications are fully covered by no-extension (one
cabinet) set-ups, but up to two units can be connected
when an expanded vertical coverage area is suitable.

*straight type only

Attractive and narrow 84mm (3.31”) design allows
speakers to fit in well with the interior decor of the venue.
Optional mounting brackets allow gap-free installation of
speakers on a wall, for an aesthetically pleasing appearance.

Space / Energy Efficient Design

Energy-efficient line array configuration requires less input
power to deliver required output.
High-quality sound reproduction even when an equalizer is
not used.

(In some situations, equalization using a digital processor is recommended,

so that Type H can best meet the specific demands of that application.)

Fully effective operation is possible without additional
amplification equipment, saving space and adding to the
unit’s cost effectiveness.

Easy & Flexible Installation

A wide variety of optional brackets is available,
for wall-mounting, rigging, and stand mounting.
Removable input terminal connectors make
hook-ups easier and less cumbersome.
For high-impedance operationm an optional
matching transformer MT-S0301 is available.

Sturdy Impact-Resistant Construction

The TOA SR-T5 is a 2-way line array
speaker featuring 8 13cm (5.2”) low
frequency cones and 24 tweeters, in
which the low and high frequency speaker
units are arranged vertically within close
proximity to each other. The curved
vertical speaker arrangement covers the
entire audience area from front to rear
with uniform sound volume. Thanks to
the excellent vertical coverage control,
reflection of sound waves off the ceiling
and walls is reduced, delivering clear sound
without causing strain on the listeners’
ears. The superb speech clarity and sturdy
impact-resistant construction of the SR­T5 make it ideal for installations in sports
facilities with strong reverberation, such as
school gymnasiums, and with no additional
protector

grille required.

Features
