The LEA Professional CS354 Connect Series 1400W 4-Channel Class-D Networked Power Amplifier with DSP, Ethernet & Wi-Fi Control is a professional-grade amplifier designed for small to medium-sized commercial audio installations. Delivering 350 watts per channel across four channels, it supports both low-impedance (2Ω, 4Ω, and 8Ω) and high-impedance (70V/100V) speaker systems, providing exceptional flexibility for distributed audio applications. Its efficient Class-D architecture ensures dependable performance while minimizing power consumption and heat generation.
Powered by a 32-bit / 96 kHz Analog Devices DSP processor, the CS354 provides advanced audio optimization with flexible input routing, 8-band parametric EQ, 48 dB/octave crossover filters, user-adjustable speaker limiters, output delay, and real-time load monitoring. LEA's proprietary Smart Power Bridge technology allows any individual channel to deliver increased output power when required without compromising the performance of the remaining channels, making it ideal for demanding commercial and installed sound environments.
The CS354 offers comprehensive network connectivity with built-in Wi-Fi, Ethernet, browser-based control, LEA Cloud remote management, and third-party API integration for seamless monitoring and system configuration. 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 on/off and fault monitoring, and a universal 100–240V switch-mode power supply with power factor correction, the CS354 is an excellent solution for houses of worship, hospitality venues, educational facilities, retail spaces, corporate environments, and other professional audio installations.
