The LEA Professional CS3004D Connect Series Dante Smart Amplifier is a four-channel, high-power professional amplifier designed for large-scale commercial audio installations. Delivering up to 3,000 watts per channel at 2Ω, 4Ω, 8Ω, 25V, and 70V/100V, it supports low-impedance loudspeakers and high-impedance distributed audio systems. Its selectable channel configuration provides flexibility for installations requiring multiple independent audio zones, high output power, and networked audio distribution.

Built around a highly efficient Class-D output stage and Analog Devices SHARC 96kHz DSP, the CS3004D provides advanced audio processing and system protection. Features include flexible input routing, linear-phase brickwall FIR crossovers, IIR crossover filters up to 48dB per octave, eight-band parametric EQ per channel, adjustable speaker limiting, and real-time load monitoring. Output delay of up to four seconds per channel supports precise audio alignment, while proprietary Smart Power Bridge technology enables bridged output functionality on two channels without sacrificing another amplifier channel.

The CS3004D offers browser-based WebUI access, third-party API control, and LEA Cloud connectivity for remote configuration, monitoring, and notifications. Its four balanced analog inputs support flexible routing through the input matrix, while Dante and AES67 connectivity support networked digital audio distribution. Network connection options include a built-in Wi-Fi access point, an existing venue Wi-Fi network, or wired Ethernet via Cat5 or Cat6 cable. External I/O supports remote on/off control and amplifier health monitoring.
