TYPE S SERIES LINE ARRAY SPEAKER SYSTEM
DESCRIPTION
FEATURES
 
 
 
 
 
 
Versatile configuration possibilities
Flexible speaker configurations can be combined to achieve 
a precision sound array with optimal response for both 
sound coverage and dispersion over the targeted listening 
area, near and distant. The result is minimal sound level 
differences whether the listener is close or distant from 
speakers.
Suits difficult environments
Type S Series speaker enclosures are designed to minimize 
floor- and ceiling reflections to maximize sound clarity in 
problematic environments that are reverberant.
High resistance to feedback
Because output levels do not become excessively high right 
close to the speakers, they are able to resist feedback to a 
high degree. Gain levels for a system are therefore easier to 
set.
Single or biamp operation
Type S Series speakers can be driven with a single amplifer 
or biamped as required (simple internal wiring change). For 
improved performance an external DSP can be used to set 
crossover frequencies and slopes.
Multiple speaker connectivity
Using optional TOA MT-SO601 matching transformers 
allows use in high impedance applications.
Heavy-duty use
Type S Series speakers are designed to satisfy the rigorous 
demands of permanent installations that are used 
extensively.
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.
The SR-S4L and SR-S4S speakers 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 
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.
