OUTSTANDING SOUND QUALITY
UNEQUALLED VERSATILITY

ST Series line arrays use advanced technology and application-driven engineering to bring vertical arrays closer to the ultimate reference point (reality) in demanding environments. Fully integrated electroacoustic systems with all elements optimized deliver superior fidelity and coverage. Wherever the venue is appropriate for a high-powered vertical array, a RHAON empowered STLA/9R or externally powered STXLA/9 line array is the logical choice for demanding designers, operators and audiences.

RHAON, the Renkus-Heinz Audio Operations Network, is the first technology to extend the power, adaptability and pristine audio performance of digital networks all the way to the loudspeaker - and to the listener in front of that loudspeaker. RHAON places total control and supervision on your computer at your fingertips, no matter how far away you are from the loudspeaker.

The PM-3R, the heart of the STLA/9R is a new kind of intelligent electronic system. It combines Class D digital tri-amplification with RHAON, the Renkus- Heinz Audio Operations Network for comprehensive DSP controlled signal processing and control.

RHAON empowers you with CobraNet digital audio distribution, user configurable DSP for maximum control, remote systems management from any Windows computer, life safety functions and more – all using standard Ethernet hardware and cable.

The PM-3R has dual analog inputs, dual CobraNet inputs and an AES3id serial input. The onboard DSP is easily configured using RHAON software; it includes eight bands of parametric EQ, high and low shelving filters, delay and input level control. Critical operating parameters such as signal clipping, amplifier output voltage and current, and temperature are continually monitored with automatic alert functions.

APPLICATIONS

• Virtually any application where outstanding sonic performance is required and sound level and coverage needs cannot be satisfied with a conventional horizontal loudspeaker array.

• Portable "touring" sound systems for both small and large concert venues, corporate AV events, etc.

• Sound reinforcement systems in large houses of worship, performing arts centers, sports arenas, theaters and other similar venues.

Renkus-Heinz Engineering has developed unique technologies to optimize line array module performance. The CDT1.5 is a co-entrant driver that integrates a 6.5-inch carbon fiber cone and a 2.5 inch voice coil titanium compression driver. The output of this high output wideband point source is shaped by our Isophasic Plane Wave Generator with Path Length Equalization Technology to approximate a plane wave (less than 1/8 wavelength curvature).

Vertical arrays radiate a continuous midrange and high frequency wavefront whose curvature is the same as that of the array. This enables the designer to control dispersion over an extraordinarily wide range – 250 Hz to 20 kHz – by varying the curvature of the array. Horizontal dispersion is also important: many line array modules produce a narrowing through the mid range transition from the woofers to the high frequency section.

The unique design of the STLA and STXLA modules avoids this by controlling horizontal dispersion from 350 Hz – 20 kHz using a common horn flare. This horn flare can be replaced in the field: 60°, 90° and 120° patterns are available to suit different venues or different sections of the vertical array. Because there is no separate midrange section, the horizontal spacing between woofers is reduced so that dispersion is consistent from 200 Hz through crossover.
