The Gisen Audio M40Q is a high-performance 4-channel Class D power amplifier designed for modern PA and installation work. Delivering up to 4 x 1300 W into 4 ohms (4 x 650 W @ 8 ohms; 4 x 1690 W @ 2 ohms), it provides ample headroom with excellent control thanks to a damping factor over 1000. A wide 20 Hz–34 kHz frequency response and low noise floor (-112 dB) ensure clean, detailed audio across music and speech applications. Connectivity is straightforward with 4 x balanced XLR inputs and Speakon outputs, while electronic level control offers precise gain management. Robust protection covers short circuit, open circuit, DC, over-temperature, RF/ultra-low frequency, and current peak limiting. The efficient front-to-rear cooling with temperature-controlled fans keeps performance stable in demanding racks. Housed in a compact 1U, 19-inch chassis (47 x 483 x 438 mm) and weighing 10.5 kg, it’s ideal where power density matters. Supplied as B-stock with full warranty for confidence out of the box. Perfect for touring racks, fixed installations, and multi-zone systems.
