ISOLINE-AX912 is a high-performance active column PA system from our ISOLINE-AX Series — engineered for larger audiences with enhanced output, dual mini EVO-Fold waveguides, and powerful Class D amplification.
Featuring a 12″ subwoofer paired with nine 3.0″ wide-range drivers and two 1.0″ HF compression drivers, ISOLINE-AX912 delivers wide, coherent coverage with exceptional clarity. Dual mini EVO-Fold waveguides — derived from our flagship WLA-1 line array technology — ensure HF projection with increased definition and audience reach.
The built-in 2-channel mixer provides mic and line inputs alongside USB playback, Bluetooth streaming, and TWS wireless stereo linking. High and low EQ controls (±9 dB) allow quick tone shaping for any environment.
With direct sub-to-column coupling and a rotatable column (+15° / -15°), setup is fast, secure, and adaptable for varied stage layouts.
Delivering 1200 W continuous (2400 W peak) power, ISOLINE-AX912 offers punch, precision, and portability in a rugged Tough-Tone black or white enclosure.
