Description
The LEA Professional CS702 Connect Series 1400W 2-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 700 watts per channel, it supports both low-impedance (2Ω, 4Ω, and 8Ω) and high-impedance (70V/100V) speaker systems, providing exceptional flexibility for a wide range of installed sound applications. Its efficient Class-D design ensures reliable performance while reducing power consumption and heat generation.
Powered by a 32-bit / 96 kHz Analog Devices Sigma DSP processor, the CS702 offers 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 a single channel to deliver double the output power when required without sacrificing the remaining amplifier channel, making it an ideal solution for demanding professional installations.
The CS702 features comprehensive network connectivity with built-in Wi-Fi, Ethernet, browser-based control, cloud management, and third-party API integration for remote monitoring and system control. Users can connect through the built-in Wi-Fi access point, an existing Wi-Fi network, or a local Ethernet network. With balanced analog inputs, external I/O for remote operation and fault monitoring, and a universal 100–240V switch-mode power supply with power factor correction, the CS702 is an excellent choice for houses of worship, hospitality venues, educational facilities, retail spaces, corporate environments, and other commercial audio installations.
