The LEA Professional CS88D is an eight-channel smart amplifier designed for small to medium-scale professional audio installations. Delivering 80 watts per channel at 4Ω, 8Ω, 25V, and 70V/100V, along with 40 watts per channel at 2Ω, it provides flexible amplification for distributed loudspeaker systems. Its Dante CONNECTSERIES platform combines analog and Dante network audio inputs with advanced digital signal processing, making it suitable for installations that require efficient audio distribution and centralized system control.

The CS88D offers three network connection methods: its built-in Wi-Fi access point, an existing venue Wi-Fi network, or a wired Ethernet LAN connection using Cat5 or Cat6 cable. The browser-based Web UI allows users to configure and monitor the amplifier from compatible devices without installing additional software. LEA Cloud adds remote control, monitoring, and notifications from virtually anywhere with an internet connection, without requiring a VPN.

Integrated 96kHz Analog Devices Sigma DSP provides flexible input routing, IIR crossover filters, eight-band parametric EQ per channel, up to 100 milliseconds of output delay per channel, adjustable speaker limiting, and real-time load monitoring. The amplifier also supports selectable low-impedance and high-impedance operation per channel, including 70V or 100V output, and features external I/O for remote on/off control and amplifier health monitoring. Its efficient Class D output stage and universal switch-mode power supply support professional installation requirements.
