The Martin Audio MA4.8Q is a high‑performance 4‑channel system amplifier in a compact 2U chassis, engineered by Lab.gruppen for modern installed sound. It offers flexible output configuration with network monitoring and control over CAT‑5, enabling precise system tuning and efficient fleet management. Adjustable maximum voltage peak and selectable gain per channel allow accurate matching to a wide range of loudspeakers, from low‑impedance full‑range cabinets to 70/100V distributed lines.
Delivering up to 1200 W per channel at 4Ω and 900 W on 70/100V lines, the MA4.8Q uses patented Class TD topology and a regulated switch‑mode power supply to maximise efficiency and maintain consistent performance under load. Protection is comprehensive, with voltage and current limiters, thermal safeguards and fuse protection. Installation is straightforward via balanced 3‑pin Phoenix inputs and barrier strip outputs, while 21‑position front‑panel gain controls provide clear, repeatable setup and fast serviceability.
Ideal for theatres, performance venues, houses of worship and large commercial installations, the MA4.8Q is a robust, networkable amplification platform for mixed low‑Z and high‑Z loudspeaker systems.
