Description
The LEA Professional CS3004 Connect Series 12000W 4-Channel Networked Smart Power Amplifier is a flagship high-power amplifier engineered for large-scale professional audio installations including stadiums, arenas, theaters, convention centers, and other demanding venues. Delivering 3000 watts per channel, it supports both low-impedance (2Ω, 4Ω, and 8Ω) and high-impedance (70V/100V) speaker systems, providing exceptional flexibility for high-output distributed audio applications. Its highly efficient Class-D architecture ensures maximum performance with reduced power consumption and heat generation.
Powered by a 32-bit / 96 kHz Analog Devices SHARC DSP processor, the CS3004 offers advanced loudspeaker management including input routing, linear-phase FIR and IIR crossover filters, 8-band parametric EQ, adjustable output delay up to 4 seconds, user-configurable speaker limiters, and real-time load monitoring. LEA's Smart Power Bridge technology allows increased output on individual channels while maintaining amplifier efficiency, making it ideal for demanding professional installations requiring maximum power and flexibility.
The CS3004 features comprehensive networking with built-in Wi-Fi, FAST Ethernet, cloud-based remote management, and browser-based configuration without requiring additional software. It also supports third-party API integration, external I/O for remote control and fault monitoring, and a universal 100–240V power supply with Power Factor Correction. Designed for mission-critical commercial audio systems, the CS3004 delivers reliable, intelligent, and scalable amplification for modern professional installations.
