The SR-S4S is a two-way line array speaker ideal for short distance sound transmission and configures a line array by arranging speaker elements vertically close to each other. It can be converted into the bi-amplifier drive system by changing the internal connection. It can be used for high-impedance applications with the installation of the optional MT-S0601 Matching Transformer.

    Slim Line Array Speakers with Clear, Well-focused Sound Enhancement

    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 reflective 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.
