Detailed Description
Connect Series Half-Rack
Part of the Connect Series Half-Rack — featuring a space-saving half-rack width (1/2U) and weighing approximately 3.2kg, maximizing rack space efficiency. An ideal choice for small-to-medium projects requiring multiple amplifiers in constrained spaces (villas, compact technical rooms, shared multi-system racks).
Key Highlights
The LEA CS34D is a 4-channel amplifier delivering 30W/channel at 4Ω, 8Ω, and 70V/100V (15W/channel at 2Ω) in a compact 1/2U form factor. Equipped with built-in Dante/AES67 ports, it enables direct digital audio transmission over LAN, completely eliminating long analog cable runs between the DSP/mixer and the amplifier. Each channel is independently selectable between low-impedance (4Ω/8Ω) and 70V/100V constant-voltage speakers via proprietary Smart Power Bridge technology — allowing a single amplifier to drive multiple disparate speaker types within the same project.
Why Choose LEA Over Traditional Amplifiers
- Remote Monitoring & Control via LEA Cloud — view real-time load status, temperature, and speaker/cable fault diagnostics for every channel directly from your mobile device, eliminating the need for on-site technician dispatches required by traditional amplifiers.
- Built-in Free DSP — pre-loaded with over 3,000 speaker tuning presets from major loudspeaker brands (JBL, Bose, Sonance...), eliminating the additional cost of outboard DSP hardware and saving manual calibration time.
- Real-Time Load Protection — automatically detects short circuits, impedance mismatches, and thermal overload, triggering protective muting before hardware damage occurs to speakers or the amplifier, thereby reducing long-term maintenance costs.
- Ideal Applications: small meeting rooms, classrooms, showrooms, and cafés — environments requiring multiple zones of moderate-power ceiling or background music speakers.
