For large-scale outdoor installations and massive event spaces, achieving uniform sound distribution without losing high-frequency clarity is a monumental challenge. This system is engineered from the ground up to conquer expansive acoustic environments with relentless energy and pinpoint accuracy.
Boasts a staggering total system power of over 20000W, providing the immense headroom needed for dynamic live performances and explosive sound effects.
Generates a maximum sound pressure level of ≥146dB, ensuring the audio physically moves the audience and cuts through dense atmospheric interference.
Maintains an effective transmission interval of over 300 meters, effectively eliminating dead zones in sprawling stadiums or military training fields.
The 15-inch mid-bass drivers and 75mm treble units work in perfect harmony to project a tight, focused beam of high-fidelity sound.
Modern audio infrastructure demands seamless connectivity, minimal signal loss, and rapid deployment capabilities. This system fully embraces the future of digital audio transport.
Fully supports the industry-standard Dante protocol, allowing for multi-channel, ultra-low latency audio transmission over standard Ethernet networks.
Support AES digital audio standards
Facilitates easy integration with existing digital mixing consoles and routing matrices, providing a true plug-and-play experience for audio engineers.
Achieving the perfect mix in an unpredictable, highly reflective acoustic space requires surgical precision and adaptable processing tools. The integrated digital signal processing architecture eliminates the need for bulky, expensive outboard gear while offering superior control over every frequency band.
Features a high-performance built-in DSP processor that handles complex audio algorithms with zero perceptible latency, ensuring immediate sonic response.
Includes customizable FIR (Finite Impulse Response) filtering to correct phase anomalies and deliver a stunningly linear frequency response across the entire spectrum.
Managing a sprawling audio network spread across a massive venue can be a logistical nightmare for technical directors. This system puts comprehensive oversight and granular control directly at your fingertips, transforming complex system management into a streamlined, intuitive process.
Enables real-time PC remote monitoring, displaying critical metrics like voltage, current, impedance, and operating temperature for every single channel.
Supports multi-unit joint control, allowing operators to group custom-named amplifiers for synchronized parameter adjustments across different venue zones.
Features remote soft power-on/off capabilities, letting you safely boot up or shut down the entire rig sequentially without leaving the central control booth.
Provides instant visual feedback on load status and allows for immediate, single-button independent muting to isolate potential issues rapidly.
Environmental unpredictability is the greatest enemy of sensitive electronic and acoustic components. We constructed this entire system to laugh in the face of harsh weather, extreme temperature fluctuations, and the rough handling inherent in mobile deployments and permanent outdoor fixtures.
The loudspeaker cabinets are constructed from exceptionally sturdy materials, coated with weather-resistant finishes that repel heavy rain and corrosive UV rays.
Engineered for high impact resistance, the enclosures can endure the inevitable bumps, drops, and vibrations associated with constant loading and unloading.
Perfectly suited for permanent outdoor installations in theme parks, city squares, where exposure to the elements is a daily reality.
A superior sound system must adapt seamlessly to the unique architectural and acoustic demands of any given event or permanent installation. This comprehensive suite offers the extraordinary versatility required to tackle diverse applications, ensuring a maximum return on your equipment investment.
The 4-channel amplifier design offers incredible load flexibility, seamlessly driving 8Ω, 4Ω, or even demanding 2Ω loads with absolute stability.
Supports bridge mode operation
Equally adept at delivering thunderous bass for live touring sound, crystal-clear announcements for public transit hubs, or immersive audio for high-end commercial venues.
