CS354D-ADSP

Audio

The LEA Professional CS354D-ADSP is the Dante-enabled Advanced DSP variant of the CS354D, a 4-channel smart amplifier delivering 350 watts per channel at 4Ω, 8Ω, 70V, and 100V (175W at 2Ω). The ADSP platform pairs an Analog Devices Sharc 96kHz processor — with linear-phase FIR crossover filters at up to 2,048 taps per channel — with native Dante and AES67 audio networking for premium live, install, and broadcast deployments.

Three ways to connect — built-in Wi-Fi access point, existing Wi-Fi, or FAST Ethernet — plus 8 × 8 Dante at 96/48 kHz and external I/O make it easy to integrate into any AV-over-IP backbone. The LEA CONNECT cloud platform, browser-based WebUI, and third-party APIs allow remote configuration and monitoring from anywhere in the world without VPN.
