Renkus-Heinz ST or STXLA9

Line Array Loudspeaker Systems


ST Series line arrays unite advanced technology and application-driven engineering to bring live sound closer to the ultimate reference point: reality. 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.


STXLA/9 loudspeakers are non-powered, for use with external amplification.


STLA/9R loudspeakers are RHAON empowered for flexible analog and digital signal distribution and loudspeaker management and control over a CAT 5 Ethernet network.


Key Features


* Heavy Duty Flying Hardware

Safely flies columns of up to 12 units, provides a wide range of aiming angles.


* Easy Rigging - Designed to Travel

Assembles easily, light in weight (the self-powered STLA/9R weighs under 190 lbs)


* Flexible Input Configurations

Choose passive inputs, or go self-powered with the PM-3R RHAON Empowered amplifier.


* Exclusive Isophasic Plane Wave Generator

Provides constant beamwidth/directivity down to 200 Hz.


* Dual CDT1.5 CoEntrant Mid/High Drivers

High Output. Individual Plane Wave Generator Lenses feeding a common waveguide maintain line array source coupling through the mid/high crossover for improved directivity in the vertical plane and a coherent wavefront.


* Dual 12-Inch Woofers

Provides smooth, low distortion performance down to 60 Hz.



PM-3R PowerNet Tri-Amplifier


The PM-3R is a new kind of intelligent electronic system. The heart of the STLA/9R, 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 cabling.


The PM-3R offers dual analog inputs, dual CobraNet inputs and an AES3id serial input. The on-board DSP includes eight bands of parametric EQ, high and low shelving filters, delay and input level control, and is easily configured using RHAON software. 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.


 

 

 

Akshardham’s Famed Fountains Get Renkus-Heinz Sound

New Delhi, India | September, 2015 - "We have worked with Renkus-Heinz on similar projects in the past, with excellent results, and we were confident that their technology was ideally suited for this type of a challenge. Their VARIA technology enabled us to design a system that would provide very precise coverage to only the audience areas, while minimizing the sound to areas that would generate problematic reflections." - Vipul Vaghela, BAPS

 

CCF Church — Massive Sound for a Massive Hall

Manila, Phillipines | July, 2014 - Founded in the early 1980s, CCF (Christ's Commission Fellowship) has grown from a 40-member evangelistic bible study group to become one of the world's mega-churches, with membership in the tens of thousands and numerous satellites across the globe. Over the years, the church has moved several times as its numbers have outgrown its seating capacity, and in May of 2013, CCF opened the doors to its new world headquarters. CCF Worship and Training Center's 750,000 square foot building is home to the church's offices and school, a youth and sports center, a 10,000-seat chapel, and a 2,000-seat overflow hall.

 

Wu-Jin’s New Phoenix Valley Cultural Center Spreads its Wings with Renkus-Heinz

Changzhou City, Jiangsu Province, China | May, 2014 - On a busy thoroughfare in Changzhou's Wujin District, the aptly named Phoenix Valley Cultural Center stretches its wings over more than 156,000 square feet. The vast complex is the largest and most modern of its kind, an urban nexus that is home to four cinemas, sports and dance halls, art galleries and an early childhood education center, as well as a retail hub, children's playgrounds, and a public square with canals and gardens.

 

Renkus-Heinz Helps Schengenfest Cap the Summer Season

Slovenia | November, 2013 - "As one of Slovenia's largest rental companies, we work on a wide range of events, from national celebrations and congresses to concerts, TV shows, and many others. We use Renkus-Heinz systems exclusively because they deliver powerful performance, they are dependable, and they sound great."
