Description
The LEA Professional CS122 is a compact 2-channel smart power amplifier purpose-built for modern AV installations, delivering 120W per channel at 4Ω, 8Ω, 70V, and 100V. Designed to provide powerful and flexible amplification in a space-saving format, the CS122 features advanced 32-bit/96kHz Analog Devices DSP, Class D output technology, and a highly efficient power supply for reliable performance with reduced power consumption.
The CS122 offers comprehensive network control and monitoring through a built-in Wi-Fi access point, existing Wi-Fi networks, or LAN Ethernet connections. Its browser-based user interface enables seamless setup and control on any device, without additional software, while LEA Cloud provides remote access and monitoring from anywhere without a VPN. Advanced DSP capabilities include input routing, sample rate conversion, 48dB/octave crossover filters, 8-band parametric EQ, adjustable speaker limiters, real-time load monitoring, and flexible signal management through Web UI, SharkWare, or cloud platforms.
Built for demanding professional installations, the CS122 supports both low-impedance and high-impedance applications with selectable 70V or 100V operation on each channel. Smart Power Bridge technology allows increased power delivery to a single channel while maintaining independent operation of the second channel. Featuring flexible analog inputs, Amphenol Anytek connectors, remote monitoring I/O, third-party API support, comprehensive protection features, and a slim half-rack chassis, the CS122 provides a powerful and scalable solution for commercial audio, hospitality, education, and advanced AV environments.
