Name: LEA Professional Connect 84 4-Channel Smart Amplifier
Brand: LEA Professional
SKU: CS84
Availability: InStock

The LEA Professional Connect 84 is an IoT-enabled install amplifier with 4 channels rated at 80 W each into 4 ohms, 8 ohms, 70V or 100V, with impedance selectable per channel so a single unit can feed low-impedance and constant-voltage zones at the same time. It suits distributed ceiling systems in offices, houses of worship, and hospitality spaces where each zone needs modest power but full remote supervision.

Setup and monitoring run in a web browser with no software to install, reached through the amplifier's own Wi-Fi access point, an existing wireless network, or a wired LAN, and the same interface is available remotely through LEA Cloud. Onboard processing is a 96 kHz Analog Devices Sigma DSP with a routable input matrix, 48 dB per octave crossovers, eight bands of parametric EQ per channel, user-adjustable speaker limiters, and real-time load monitoring. An external I/O port handles remote power and fault reporting, and the universal switch-mode supply with power factor correction runs on anything from 100 to 240 VAC. The D models add Dante audio over IP alongside the analog inputs.
