The RLA/4 (LS7500) full-range, bi-amped true line source array module was developed for a wide range of applications—from permanent sound reinforcement installations in churches, auditoriums, arenas and performing arts centers, to a professional portable P.A. system. Its high-frequency section features a high-performance PRD500 planar ribbon transducer designed and manufactured by SLS. The unique design and properties of the planar ribbon driver allows precise acoustical coupling of the array and full utilization of line source (cylindrical waves) benefits.

The low-frequency section uses two high-powered 6.5-inch drivers using a demodulation ring magnet system providing a third less harmonic distortion and reducing inductance modulation by 50 percent. This provides an open and clear sound despite loud listening levels. Additionally, the LF drivers feature a die-cast basket with a patented Intercooler system.
 
The system offers 90-degree-wide symmetrical horizontal coverage and offers SLS’ free LASS prediction software that visually shows the ideal set up locations for even, predictable sound coverage of any room. Each RLA/4 module is designed for bi-amplification. All array rigging is included on the cabinet that is made from sturdy ¾-inch 13-ply Baltic Birch, and includes splay options from 1 to 10 degrees between boxes.
