Among TOA's wide range of sound reinforcement products, SR-S4 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 SR-S4 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 offer a perfect solution for difficult sound reinforcement problems that require effective coverage.
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.
The speakers' construction and characteristics make them resist floor- and ceiling-originating reflections, enhancing clarity even in reverberant spaces and other problem
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.
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.
