The Gisen Audio M40Q is a compact, high-output 4-channel Class-D power amplifier designed for demanding professional audio environments. This B-stock unit has been fully tested and includes a full 2-year warranty; it may show minor cosmetic signs of previous use but is in perfect working order. Delivering 4 x 650 W RMS into 8 Ω or 4 x 1300 W RMS into 4 Ω, it offers generous headroom in a lightweight 1U chassis under 13 kg, maximising rack space and portability. Balanced XLR inputs and Speakon outputs keep setup straightforward, while intelligent, temperature-controlled cooling and overheat protection ensure reliability under sustained loads. Front-panel electronic level control with clear display enables precise, repeatable configuration. With a damping factor >1000 (8 Ω), THD <0.1% (20 Hz–20 kHz, 1 W), and a flat 20 Hz–20 kHz response (±0.3 dB), the M40Q delivers tight low-end authority and clean, musical performance. Ideal for touring racks, rental fleets, and fixed installations powering tops, subs, or stage monitors.
