Detailed Description
Connect Series ADSP
Part of the Connect Series ADSP — the advanced DSP version featuring 96kHz linear-phase FIR crossover filters (2048 taps/ch), up to 4 seconds of input delay, and boot times under 10 seconds when powered via PoE. This is LEA’s highest-performance lineup, designed for systems requiring absolute precision in main speaker tuning (line arrays, multi-speaker setups demanding strict phase alignment).
Key Highlights
The LEA CS704D-ADSP is a 4-channel amplifier delivering 700W/channel at 4Ω, 8Ω, and 70V/100V (350W/channel at 2Ω) in a 2U rack-mount design. Featuring built-in Dante/AES67 ports, it enables direct digital signal transmission over LAN, completely eliminating long analog cable runs between the DSP/mixer and the amplifier. Each channel can be independently configured for low-impedance loudspeakers (4Ω/8Ω) or 70V/100V distributed systems thanks to proprietary Smart Power Bridge technology — allowing a single amplifier to drive multiple types of speaker systems within the same project.
Why Choose LEA Over Traditional Amplifiers
- Remote Monitoring & Control via LEA Cloud — View load status, temperature, and speaker/cabling faults for each channel directly from your mobile device, eliminating the need for on-site technician dispatches required by traditional amplifiers.
- Free Built-In DSP — Includes over 3,000 pre-loaded loudspeaker tuning presets from major speaker brands (JBL, Bose, Sonance...), eliminating extra hardware costs for outboard DSP or manual tuning time.
- Real-Time Load Monitoring — Automatically detects short circuits, impedance mismatches, and overheating, engaging protective shutoff before speaker or amplifier damage occurs, reducing long-term maintenance costs.
- Ideal For: Live performance venues, houses of worship/large auditoriums, and commercial shopping centers.
