High quality sound reinforcement equipment for demanding environments.

LINE ARRAY SPEAKER

SYSTEMS

Among TOA's wide range of sound reinforcement

products, Line Array Speaker Systems play an

important role in providing high quality audio for

medium sized venues that can range from places of

worship, gymnasiums, to various sports facilities and

other problematic environments. TOA Line Array

Speaker Systems are designed to perform optimally

with ideal sound dispersion characteristics in spaces

that pose difficulties for more conventional speaker

systems. Available in different configurations and

with a wide range of mounting possibilities to suit

particular requirements precisely, these slim tower-

configured speakers and modular speaker systems

offer perfect solutions for difficult sound

reinforcement problems that require effective

coverage.

Driver complement

Both speaker types are 2-way line array speakers, each

containing 32 speaker elements-8 x 10cm woofers and 24

high frequency drivers. Driver units are installed vertically and

with minimal space between units in order to create a

continuous linear sound source. This enables delivering a

uniform sound pressure that resists attenuation with distance.

Sound dispersion

characteristics

The SR-S4L speaker features

a linear design tailored for

distance sound transmission

applications and the SR-S4S

features a gently curved line

designed for a 10°vertical

coverage area which offers

ideal sound coverage over a

shorter distance.

Directed sound dispersion

Type S Series speakers limit vertical sound dispersion in order to

focus directivity at the targeted listening area.

Multi-speaker array-configurable

Both systems can be combined to realize a versatile speaker

array that performs equally well in terms of sound coverage

and dispersion over short and long distances. Less

difference in sound level is perceived whether close to or

somewhat distant from the speakers, providing a uniform

response. Individual speaker systems of each type can be

assembled together as multiple configurations, acting as

longer sound sources that can deliver greater output as well

as project the sound a greater distance.

Reflection-free

The speakers' construction and characteristics make them

resist floor- and ceiling-originating reflections, enhancing

clarity even in reverberant spaces and other problem

environments.

Feedback-resistant

The design of the speakers also makes them highly resistant to

annoying feedback because volume levels are not extraordinarily

high even close to the speakers and makes setting gain levels

easier.

Biamp or single amp drive

Factory-set for single amplifier driving, the Type S series speakers

can simply be set for biamping by making a simple internal wiring

change. For optimal biamping, a digital signal processor can be

employed to set crossover frequency points.

High impedance-compatible

The speaker can also be conveniently set for high-impedance

applications by using the optional MT-S0601 matching

transformer. This option is only possible when driving the speaker

with a single amplifier.

SR-S4LWP

TOA Line Array Speaker Systems are designed for

permanent installations and are available in slim, tower-

configured types, the SR-S4L and SR-S4S (Type S).

For installations where greater sound output with a

wider frequency response are required, the modular

SR-A12L, the SR-A12S and a companion SR-A18B

(Type A) low frequency module can be utilized. A

wide range of mounting brackets enables flexible

speaker mounting options for the best sound

coverage characteristics.

Wide frequency range

Offering greater output levels with wider frequency response, the

SR-A12 modular speaker units are compact but powerful 2-way

configurations.

Drive complement

Each speaker features a 12" woofer and a high-frequency horn

that is connected to 2 high-performance compression drivers.

TOA's horn features a proprietary phase front wave control throat

that realizes the best performance from the compression drivers.

Each speaker is loaded with two high-performance compression

drivers to achieve greater output.

Sound coverage options

Type A Series includes one speaker configuration with a

5-degree taper specifically designed to transmit sound over

distance as well as a 15-degree taper configuration which provides

greater short range coverage. Both configurations may be

combined as required to achieve uniform sound coverage in

various environments.

Ideal for permanent installations

Type A Series are capable of high-quality sound with ideal

coverage and dispersion characteristics in environments that

used to pose severe difficulties for permanent installations,

especially when high fidelity sound is desired.

Easy maintenance and servicing

Keeping operational

requirements in mind,

TOA has made it possible to

quickly replace the low

frequency driver as well as

the high frequency driver from

the rear of the enclosure.

In a permanent installation,

ease of service and

maintenance are important

points to consider.
