Description
The LEA Professional CS88 Connect Series 640W 8-Channel Networked Smart Power Amplifier is a professional-grade amplifier designed for multi-zone commercial audio installations in corporate facilities, educational campuses, hospitality venues, houses of worship, and retail environments. Delivering 80 watts per channel across eight channels, it supports both low-impedance (2Ω, 4Ω, and 8Ω) and high-impedance (70V/100V) speaker systems, providing outstanding flexibility for distributed audio applications. Its efficient Class-D design delivers reliable performance while minimizing power consumption and heat generation.
Powered by a 32-bit / 96 kHz Analog Devices Sigma DSP processor, the CS88 provides advanced loudspeaker management including flexible input routing, 8-band parametric EQ, 48 dB/octave crossover filters, adjustable output delay, speaker limiters, and real-time load monitoring. LEA's Smart Power Bridge technology allows additional power to be delivered to individual channels when required without sacrificing amplifier performance, making it ideal for demanding installed sound systems.
The CS88 offers 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 IoT-enabled monitoring through the LEA Cloud platform. With balanced analog inputs and a compact 1U rackmount design, the CS88 delivers powerful, intelligent, and scalable amplification for professional audio installations.
