Gisen Audio’s M20D is a high‑efficiency 2‑channel Class‑D power amplifier housed in a compact 1U, 19‑inch chassis. Delivering 2 x 650 W RMS at 8 Ω or 2 x 1300 W RMS at 4 Ω, it offers ample clean headroom for modern PA loudspeakers. Balanced XLR inputs and Speakon outputs ensure straightforward integration, while the front‑panel display and buttons provide precise, electronically controlled level adjustment for fast, repeatable setup. With a damping factor greater than 1000 (8 Ω) and THD below 0.1% (20 Hz–20 kHz, 1 W), the M20D delivers tight low‑end control and transparent, musical performance across a flat 20 Hz–20 kHz response (±0.3 dB). Temperature‑controlled fans and built‑in overheat protection support reliable operation under sustained loads. Despite its robust output, it remains practical at just 13 kg with a 448 mm rack depth, making transport and installation easy without sacrificing power density. This listing is for a B‑stock unit. Ideal for rental, touring racks and fixed installs seeking efficiency, clarity and durability in a compact footprint.
