Description
The LEA Professional CS1504 Connect Series 6000W 4-Channel Class-D Networked Power Amplifier with DSP, Ethernet & Wi-Fi Control is a high-performance professional amplifier engineered for medium-sized commercial and installed sound systems. Delivering 1,500 watts per channel across four channels, it supports low-impedance (2Ω, 4Ω, and 8Ω) as well as high-impedance (70V/100V) speaker systems, offering exceptional flexibility for demanding distributed audio applications. Its efficient Class-D architecture provides outstanding power while minimizing energy consumption and heat generation.
Powered by a 32-bit / 96 kHz Analog Devices SHARC DSP processor, the CS1504 offers advanced signal processing with flexible input routing, 8-band parametric EQ, IIR and FIR crossover filters, up to 4 seconds of output delay, user-adjustable peak and RMS limiting, and real-time load monitoring. LEA's proprietary Smart Power Bridge technology enables increased output power on selected channels without sacrificing amplifier performance, making it ideal for high-power commercial audio installations.
The CS1504 features comprehensive network connectivity with built-in Wi-Fi, Ethernet with PoE support, browser-based control, LEA Cloud remote management, SharkWare software compatibility, and third-party API integration. Users can connect through the built-in Wi-Fi access point, an existing Wi-Fi network, or a local Ethernet network. Combined with balanced analog inputs, external I/O for remote control and fault monitoring, and a universal 100–240V switch-mode power supply with power factor correction, the CS1504 is an excellent choice for stadiums, arenas, houses of worship, hospitality venues, educational facilities, corporate environments, and other professional audio installations requiring high output power.
