The LEA Professional CS702D Dante Connect Series is a two-channel professional amplifier designed for installed audio systems that need substantial power, flexible loudspeaker configuration, and remote system management. It delivers 700 watts per channel at 4Ω, 8Ω, 25V, 70V, and 100V, with 350 watts per channel at 2Ω. Each channel can be configured independently for low-impedance, 70V, or 100V operation, giving installers flexibility when deploying different loudspeaker types across commercial sound systems.

The CS702D combines two balanced analog inputs with an 8 × 8 Dante audio interface supporting 96kHz or 48kHz operation. Its 96kHz Analog Devices Sigma DSP processor provides a routable input matrix with primary and secondary input priority, eight-band parametric EQ per channel, crossover filters up to 48dB per octave, and 100ms of output delay per channel. Smart Power Bridge Technology enables bridged output functionality without sacrificing an amplifier channel, while integrated protection and real-time load monitoring support system management.

For installation and ongoing operation, the CS702D offers built-in Wi-Fi access, connection to an existing Wi-Fi network, or wired Ethernet. The browser-based WebUI, LEA Cloud, and third-party API control provide options for remote configuration and monitoring. An external I/O port supports remote on/off control and amplifier-health indication, while the Class D output stage and universal switch-mode power supply with power factor correction are designed for efficient operation in professional audio environments.
