Description
The LEA Professional CS124 is a powerful 4-channel Class D smart power amplifier designed for small to medium-sized sound installations requiring high performance, flexibility, and reliable network control. Delivering 120W per channel, the CS124 supports both low-impedance and high-impedance applications with selectable 70V or 100V operation on each channel. Featuring an advanced 32-bit/96kHz DSP processor and Smart Power Bridge technology, the CS124 provides professional audio processing and efficient amplification in a compact half-rack form factor.
Built for modern AV environments, the CS124 offers flexible connectivity through a built-in Wi-Fi access point, connection to an existing Wi-Fi network, or Cat 5/Cat 6 Ethernet. Its browser-based Web UI allows users to configure and monitor the amplifier from any device without additional software, while LEA Cloud enables remote control and monitoring from anywhere. Advanced DSP capabilities include input routing, linear-phase FIR filters, 48dB/octave crossover filters, 8-band parametric EQ, user-configurable speaker limiters, real-time load monitoring, and up to 4 seconds of output delay. Third-party API support and fully routable analog inputs provide seamless integration with professional control systems.
Designed for efficient and dependable operation, the CS124 features a highly efficient Class D output stage, universal switch-mode power supply, and flexible balanced and unbalanced I/O connections using professional-grade Amphenol Anytek connectors. Smart Power Bridge technology allows users to dynamically double the power of any single channel without affecting the performance of the remaining channels. Complete with I/O connectors, power cable, and advanced protection features, the CS124 is an ideal solution for commercial audio, hospitality, education, corporate, and professional AV installations.
