The Gisen Audio M45.9 is a three‑channel amplifier module with onboard DSP, designed for building high‑performance active loudspeakers. Ideal for 2.1 systems or active three‑way designs, it delivers 2 × 450 W + 900 W at 8 Ω or 2 × 720 W + 1440 W at 4 Ω, providing ample headroom and control. A four‑channel DSP (using outputs A, B and C on this module) offers input and output EQ, high‑pass/low‑pass filters, delay and peak limiting, with up to 20 user presets. Control is via the front‑panel encoder or software.
Connectivity includes two balanced XLR inputs with parallel audio outputs, plus loudspeaker connections via Speakon or KF25C‑7.62 screw terminals. Performance is refined with a 20 Hz–20 kHz response (±0.3 dB at 1 W/8 Ω), SNR of −95 dB, THD <0.1%, and a damping factor >400. Temperature‑regulated cooling and comprehensive protection—short circuit, no load, DC, thermal, over‑voltage, RF and subsonic—ensure reliable operation. Universal mains input (AC 180–240 V or 90–120 V, 50–60 Hz), compact 280 × 360 × 88 mm size and 6.4 kg weight suit integration into enclosures.
Perfect for OEM and custom builds where controlled, multi‑channel power and precise DSP shaping are required.
