The Lambda Labs KW-18 is a 4‑channel high‑power amplifier engineered for demanding live sound and installation environments. Delivering up to 4 x 2300 W at 8 Ω and 4 x 4500 W at 4 Ω (all channels driven), it provides exceptional headroom for large-format loudspeakers and subwoofers. A wide 10 Hz–50 kHz frequency response (+0/‑3 dB), low THD+N of 0.02% (typ., 20 Hz–20 kHz at half power), and an impressive damping factor of 800 @ 1 kHz/8 Ω ensure tight, controlled low end and clean, detailed reproduction across the spectrum.
Operational reliability is supported by comprehensive protection: over/undervoltage, peak/RMS input current limiting, short‑circuit, DC output, thermal, and peak/RMS output voltage/current limiting. Clear front‑panel status LEDs show AC OK, fault, limit and signal states for quick diagnostics. With a 3‑phase 90–255 Vac input range and modest 3 x 8 A RMS draw at 230 Vac (1/8 power), the KW-18 integrates smoothly into professional power schemes. Housed in a compact 2U chassis (483 x 89 x 584 mm) and weighing 18 kg, it’s built for touring racks and fixed installations alike.
Ideal for driving modern PA systems, subwoofer arrays and multi‑zone installs where output, control and reliability are paramount.
