High quality sound reinforcement equipment for demanding environments.

LINE ARRAY SPEAKER

SYSTEMS

Versatile operational and installation feature

s

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 tower­configured speakers and modular speaker systems
offer perfect solutions for difficult sound
reinforcement problems that require effective
coverage.

Type S Series Main Features

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.
