M-A9
M-A9 is a premium self-powered column system for events and installations that demand bigger headroom, deeper bass, and unwavering reliability. It blends an elegant, unobtrusive look with modern connectivity, Bluetooth audio and True Wireless Stereo, and a carefully voiced four-way design. Ideal for corporate productions, conference and convention spaces, hotels and hospitality, houses of worship, exhibitions, and indoor live music, M-A9 delivers natural speech intelligibility and full, engaging music without visual clutter.
- Self-powered, plug‑and‑play column system with four‑way acoustic design
- Extended low‑frequency authority with independent sub level control
- Bluetooth audio and True Wireless Stereo for fast, cable‑free stereo setups
- Dual SMPS architecture for exceptional stability and sustained output
- Refined, durable design for corporate events, conferencing, hospitality, worship, exhibitions, and indoor live music
Engineered for scenarios where authority and finesse must coexist, M-A9 advances the column concept with a four-way, DSP‑optimised architecture. A robust subwoofer base anchors a two‑piece aluminium column that combines dedicated low‑mid and mid arrays with a multicell waveguide for the highs. This acoustic design keeps speech articulate and music balanced, while the waveguide shapes the sound field so that near and far listeners experience consistent clarity. The extended low‑frequency capability adds weight and impact without sacrificing the system’s slim, architectural profile. M-A9 is purpose‑built for dependable, everyday operation. Its self‑powered platform employs multiple Class‑D amplifier channels with a dual SMPS power supply running in an optimised phase mode. The result is exceptional stability and sustained output—even during long sessions and in demanding thermal conditions. Low‑noise conversion, comprehensive protection, and carefully tuned factory voicings underpin predictable performance from setup to teardown. Day‑to‑day control is straightforward: a master level governs overall balance, while an independent subwoofer level lets you tailor the low end to the room and programme. Bluetooth connectivity enables quick cable‑free playback, and TWS pairing links two systems for true stereo without additional hardware. Designed to work beautifully and look refined, M-A9 integrates cleanly into contemporary interiors and polished event environments. The coated wooden subwoofer cabinet provides a stable, durable base; the slim, two‑piece column locks securely for fast assembly, easy transport, and a tidy footprint on site. With practical accessories for protection and mobility, M-A9 is equally at home in permanent installations and on the move.
