Each channel drives low-impedance speakers or 70V/100V lines, set per channel.

How does the LEA Professional CS354-ADSP work?
The CS354-ADSP delivers 4 x 350W (1,400W total) from a Class D output stage. FIR filtering gives phase-coherent crossovers for high-performance speakers, and the long input delay aligns distant speaker zones. Everything else in the Connect Series is here too: Smart Power Bridge, load and fault monitoring, Web UI, SharkWare, and LEA Cloud.
