The Lambda Labs KW-18 is a 4‑channel high‑power amplifier built for demanding touring and installation projects. Delivering up to 4 x 2300 W at 8 Ω and 4 x 4500 W at 4 Ω (all channels driven), it offers exceptional headroom for large full‑range cabinets and high‑impact subwoofers. A wide 10 Hz–50 kHz response (+0/‑3 dB) and low 0.02% THD+N at half power ensure clean, detailed reproduction, while a damping factor of 800 (1 kHz/8 Ω) keeps low frequencies tight and controlled.
Rugged and dependable, the KW-18 features comprehensive protection including over/undervoltage, short‑circuit, DC output, thermal, and peak/RMS limiting on input and output stages. Front‑panel LEDs provide quick status feedback for AC, fault, limit and signal. A 3‑phase 90–255 Vac input range and efficient 3 x 8 A RMS draw at 230 Vac (1/8 power) make it easy to integrate into professional power systems. Housed in a compact 2U chassis and weighing 18 kg, it’s ideal for touring racks and fixed installs.
Perfect for driving modern PA systems, sub arrays and multi‑zone sound reinforcement where power, control and reliability are essential.
