Line Array SpeakerType S

Versatile operation and installation features

enhance sound reinforcement applications

TOA Type S Series Line Array Speakers provide

optimal coverage and dispersion characteristics.

Available in slim, tower-configured enclosures,

these speakers also feature a wide range of

mounting accessories to enable permanent

installation in various venues.

Type S Series are 2-way line array speakers

that are vertically configured. Each configuration

contains 32 speaker elements composed of

eight 10cm woofers and 24 high frequency

drivers which are positioned close together to

create a continuous linear sound source. The

speaker output therefore maintains a uniform

sound pressure level that resists attenuation

with distance. The SR-S4L/S4LWP speaker

features a linear design tailored for distance

sound transmission applications and the SR-S4S/

S4SWP features a gently curved line which offers

ideal sound coverage over a shorter distance.

SR-S4L SR-S4S

Line Array Type S are 2-way line array speakers, each containing 32 speaker elements - 8 x 10 cm LF and 24 HF 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.

SR-S4L/S4LWP is designed for long distance sound transmission, whilst SR-S4S/S4SWP is for short distance sound transmission. Stacking 2 or 3 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.

Type S has a built-in network circuit for a single amplifier drive. Changing the internal connector position enables bi-amplifier drive that provides a higher quality sound output.

The speaker enclosures are designed to minimize floor- and ceiling reflections to maximize sound clarity even in reverberant spaces and other problem environments.

Using optional TOA MT-S0601 Matching Transformer allows use in high impedance applications.

Sync-Drive is a wavefront control technology that keeps sound waves in phase with their sources at the speakers to create an ideal linear sound source. TOA’s line array speakers incorporate this technology.

• Sync-Drive technology creates ideal linear sound source, ensuring

more intelligibility with reduced attenuation over distance

• Versatile speaker configuration possibilities

• Bi-amp operation capability for higher quality sound

• Ideal for challenging environments

• Multiple speaker connectivity
