Description
The LEA Professional CDS352 Cinema Digital Series Smart Amplifier is a two-channel professional amplifier designed for small- to medium-scale commercial audio installations. Delivering up to 350 watts per channel at 4Ω, 8Ω, 25V, and 70V/100V, it supports low-impedance loudspeakers and high-impedance distributed audio systems. With selectable output modes for each channel, the CDS352 offers flexible configuration for installations requiring independent audio zones, reliable amplification, and network-based system management.
Built around a highly efficient Class-D output stage and Analog Devices Sigma 96kHz DSP, the CDS352 provides integrated audio processing and system protection. Features include flexible input routing, crossover filters up to 48dB per octave, eight-band parametric EQ per channel, adjustable speaker limiting, and real-time load monitoring. Proprietary Smart Power Bridge technology enables bridged output functionality without sacrificing another amplifier channel, while built-in sample rate converters support flexible digital audio integration.
The CDS352 offers browser-based WebUI access, third-party API control, LEA Cloud connectivity, and SharkWare support for system configuration and monitoring. Its balanced analog inputs and 8 × 8 AES67 audio interface support flexible routing and networked audio distribution. Connectivity options include a built-in Wi-Fi access point, an existing venue Wi-Fi network, or wired Ethernet via Cat5 or Cat6 cable. External I/O supports remote on/off control and amplifier health monitoring.
