LEA Professional Connect 164 4-Channel Smart Amplifier

The LEA Professional Connect 164 is an IoT-enabled install amplifier with 4 channels rated at 160 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 handles mixed low-impedance and 70V zones in schools, worship venues, and multi-room hospitality installs from a single rack space.

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.
