Description
The LEA Professional CS84 Connect Series 320W 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 80 watts per channel across four channels, it supports both low-impedance (4Ω and 8Ω) and high-impedance (70V/100V) speaker systems with independent channel selection. Its highly 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 CS84 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 Smart Power Bridge technology allows users to increase the output power of an individual channel without sacrificing the remaining amplifier channels, making it ideal for demanding installed sound applications.
The CS84 offers comprehensive network connectivity with built-in Wi-Fi, Ethernet, browser-based control, LEA Cloud remote management, and third-party API support for seamless system 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 on/off and fault monitoring, and a universal 100–240V switch-mode power supply with power factor correction, the CS84 is an excellent solution for houses of worship, schools, hospitality venues, retail spaces, corporate facilities, and other professional audio installations.
