Key Applications Of Fixed Installation.

Stadiums / Large Public Venues
Long-throw, high-SPL reinforcement. Requires high power and strong current delivery.
Theaters / Concert Halls
High-fidelity, multi-zone systems (main, fill, surround, sub). Demands exceptional sonic accuracy.
Convention Centers / Lecture Halls
High speech intelligibility. Often paired with constant-voltage or DSP-enabled amplifiers.
Theme Parks / Tourist Attractions
Harsh environments. Requires rugged, weather-resistant, and durable amplifiers.
Transportation Hubs
Background Music (BGM) and Public Address (PA). Primarily use Constant-Voltage Amplifiers for long-distance distribution.
Churches / Houses of Worship
Balance between speech clarity and musical reproduction.

AMP Auto-Backup System

During operation, if the main amplifier enters protection mode or malfunctions and ceases output, the intelligent detection system immediately triggers a signal to the backup amplifier. The system then seamlessly switches the backup amplifier’s output to replace that of the failed or protected main amplifier, ensuring uninterrupted sound amplification on site.
 Composition: KE826A (Processor) + main amplifiers (Intelligent Network Power Amplifier Series (Two Channels) ) + backup amplifier (Intelligent Network Power Amplifier Series (Two Channels) ) + Network system + accessories. 
 Amplifier backup; Speaker & amp remote monitoring
 Various combination options.
 Dante, DSP, AES
