Descripción
The LEA Professional CS352D-ADSP Dante Connect Series Smart Amplifier is a two-channel Class-D amplifier designed for professional audio installations requiring flexible connectivity, precise processing, and reliable performance. It delivers 350 watts per channel at 4Ω, 8Ω, 25V, and 70V/100V, with a rated output of 175 watts per channel at 2Ω. Support for low-impedance and high-impedance loudspeaker systems makes it suitable for a wide range of installed audio applications.
The amplifier features a 96kHz Analog Devices SHARC DSP processor with a 32-bit core and sample rate converters. Its processing tools include 2048-tap linear-phase FIR filters per channel, IIR crossover filters up to 48dB per octave, eight-band parametric EQ per channel, and up to four seconds of output delay per channel. User-adjustable voltage limiters, input routing, and real-time load monitoring help installers configure and manage loudspeaker systems with precision.
The CS352D-ADSP combines balanced analog inputs with 8 × 8 Dante audio networking at 48kHz or 96kHz and configurable AES67 compatibility. LEA Cloud enables remote control, monitoring, and notifications without requiring a VPN, while the browser-based WebUI, third-party API, and SharkWare provide additional control options. Built-in Wi-Fi, LAN connectivity, and external I/O for remote on/off and amplifier health monitoring support integration into modern professional AV systems.
