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-up in under 10 seconds when powered via PoE. This is LEA's highest-performance line, designed for systems requiring absolute precision in main speaker tuning (line arrays, multi-speaker systems requiring strict phase alignment).
Key Features
The LEA CS704-ADSP is a 4-channel amplifier delivering 700W/ch at 4Ω, 8Ω, and 70V/100V (350W/ch at 2Ω) in a 2U rack-mount design. Each channel can be independently selected between low-impedance speakers (4Ω/8Ω) and 70V/100V distributed speaker systems thanks to proprietary Smart Power Bridge technology — allowing a single amplifier to drive multiple types of speaker loads within the same project.
Why Choose LEA Over Traditional Amplifiers
- Remote Monitoring & Control via LEA Cloud — view load status, temperature, and speaker/cable 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 — over 3,000 factory speaker tuning presets from major brands (JBL, Bose, Sonance, etc.), saving additional costs on outboard DSP and hours of manual tuning.
- Real-Time Load Monitoring — automatically detects short circuits, impedance mismatch, and thermal overload, engaging protection before speaker or amplifier damage occurs, significantly reducing future maintenance costs.
- Ideal For: event stages, large houses of worship/auditoriums, and commercial shopping centers.
