Description
The LEA Professional CS64 is a compact 4-channel Class D smart power amplifier designed for small to medium-sized sound installations. Delivering 60W per channel, it supports both low-impedance and high-impedance speaker systems with selectable 70V or 100V operation on each channel. Powered by an advanced 32-bit/96kHz DSP engine and Smart Power Bridge technology, the CS64 combines powerful audio processing with exceptional flexibility in a space-saving half-rack chassis.
Designed for modern networked AV systems, the CS64 offers three convenient connectivity options: 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 enables configuration and monitoring from virtually any device without requiring software installation, while LEA Cloud provides secure remote management 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 extensive delay processing. Third-party API support and balanced analog I/O with GPI/O allow seamless integration into professional control systems.
Built for dependable, energy-efficient operation, the CS64 features a universal switch-mode power supply with a highly efficient Class D output stage for reduced power consumption. Balanced Amphenol Anytek connectors, unbalanced RCA inputs, and Smart Power Bridge technology provide flexible installation options while maintaining maximum performance. Supplied with I/O connectors and a power cord, the CS64 is an ideal amplifier for commercial audio, hospitality, education, corporate, and other professional AV applications.
