The Martin Audio MA4.8Q is a high‑performance 4‑channel system amplifier in a compact 2U chassis, engineered by Lab.gruppen for demanding installed sound. It combines flexible output configuration with network monitoring and control over CAT‑5, enabling precise system tuning, status visibility and efficient fleet management. Per‑channel selectable gain and adjustable maximum voltage peak allow accurate matching to both low‑impedance loudspeakers and 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. Comprehensive protection includes voltage and current limiters, thermal safeguards and fuse protection for reliable operation. Installation is straightforward via balanced 3‑pin Phoenix inputs and barrier strip outputs, while 21‑position front‑panel gain controls ensure clear, repeatable setup and fast serviceability.
Ideal for theatres, performance venues, houses of worship and large commercial installations, the MA4.8Q provides robust, networkable amplification for mixed low‑Z and high‑Z loudspeaker systems.
