The LEA Professional CS1504D-G Connect Series Dante Smart Amplifier is a four-channel, high-power professional amplifier designed for demanding commercial audio installations. Delivering up to 1,500 watts per channel at 2Ω, 4Ω, 8Ω, and 70V/100V, it supports low-impedance loudspeakers and high-impedance distributed audio systems. Its selectable output configuration makes it suitable for installations requiring multiple independent audio zones and powerful networked audio distribution. At 25V, the amplifier is rated at 600 watts per channel.

Built around a highly efficient Class-D output stage and Analog Devices 96kHz DSP, the CS1504D-G 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 voltage 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 without sacrificing another amplifier channel.

The CS1504D-G 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 external I/O provides remote on/off control and amplifier health monitoring. This G-model uses a wired LAN connection and does not support Wi-Fi. The CS1504D-G is the Dante version of the Connect Series amplifier.
