Self-powered PowerNet ST4LR Series loudspeakers unite advanced technology and application-driven engineering to bring live sound closer to the ultimate reference point: reality. Patented CoEntrant Mid/Hi transducers, Class-D digital amplification, and unique innovations like our Complex Conic Horns combine to deliver natural sounding music and intelligible speech. Wherever audiences and operators demand superior performance and ease of use, ST/STX Series loudspeakers are an excellent choice for transparent, reference quality performance.
ST4LR PowerNet loudspeakers include the integrated PM-1LR PowerNet digital amplifier with RHAON for flexible analog and digital signal distribution and loudspeaker management and control over a CAT 5 Ethernet network.
Key Features
• Compact Dual 12-Inch LF Modules
A perfect complement to the ST/STX4 when additional low frequency energy is required.
• Flexible Input Configurations
Self-powered with the PM1LR PowerNet Amplifier with RHAON for flexible analog and multi-channel digital signal distribution, computer control and supervision.
• Dipolar Low Frequency Design
Provides superior low frequency directional control in the vertical plane.
• High Power, High Performance 12-Inch Woofers
Accurate 40 Hz to 500 Hz response, 133 dB peak SPL performance
• Trapezoidal Enclosures
Identical in size and shape to the ST4R full range loudspeakers.
PM-1LR PowerNet Digital Amplifier
Passive or self-powered and networked, choose the system configuration that meets your needs. Select the STX4L when the project dictates the use of external amplifiers and the self-powered PowerNet ST5LR for convenience and control in other applications.
The PM-1LR, the heart of the PowerNet ST4LR, is a new kind of intelligent electronic system. It combines Class D digital bi-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-1LR 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 low frequency directional control and arrayability are critical issues and outstanding sonic performance is required.
• Distributed systems in sports arenas and stadiums, Multi-channel A/V playback systems, live sound and music systems in dance clubs (with associated ST4R and STX4 full-range 3-way loudspeakers).
• Array modules for theatrical and concert sound systems, sound reinforcement systems in houses of worship, performing art centers, etc..
