While Martin Audio’s Multi-cellular Loudspeaker Array [MLA] technology represents the ultimate in coverage control, with individually powered and processed cells within each enclosure, the scalable resolution of WPC [Wavefront Precision Compact] offers greatly improved coverage consistency and control compared to a standard line array and provides a flexible pathway to advanced array control. 


제품 특징
  • Compact line array
  • Scalable resolution for advanced array control 
  • External, dedicated, multi-channel Class D amplification
  • Industry-leading DISPLAY software interacts with DSP for highly-accurate results
  • Fast, integral 3-point flying systems for up to 16 enclosures
  • Side and rear handles for ease of handling and setting splay angles
  • 100° horizontal constant directivity pattern control


제품 장점
  •  Consistent coverage achieved ‘straight-out-of-the-box’
  • DISPLAY intelligent software reduces set-up time and eliminates trial-and-error
  • Improved audience coverage with reduced sound-spill
제품 적용
  • Touring sound reinforcement for small and medium-size venues
  •  Fixed installations in concert halls, theatres, ballrooms and HoW
  •  Sports stadium, arena installations & corporate AV events


The WPC is a new breed of medium-format optimised line array which brings innovative acoustic design, ultra-high performance and coverage consistency to a wider range of users, applications and budgets than previously possible. A three-way, bi-amp system, it features horn-loaded low-frequency, mid and HF sections to raise efficiency and increase output.  Its high efficiency acoustic design can equal or outperform larger, direct radiator systems — a 12-box array will throw beyond 60 metres (200ft)  and deliver impressive rock levels to a 5000-seat venue, saving on truck space and weight.


The WPC’s low frequency section consists of 2 x 10” (250mm) neodymium drivers in a Hybrid® configuration which marries the benefits of horn and reflex loading.  Each driver is slot-loaded into a short horn to give a high sensitivity of 103dB @ m/2.83V, while the rear of the driver is reflex-loaded to extend the LF output. The punch and low-frequency extension produced from such a small enclosure volume are remarkable.

Mid and HF horns are physically separate — a key factor in the WPC’s exemplary 100° horizontal constant directivity dispersion pattern. The midrange horn design utilises 2 x 5” (125mm) neodymium drivers to produce a high SPL of 109dB @ 1m/2.83V, while the HF section employs 4 x 0.7” (19mm) exit neodymium compression drivers which feed 4 individual horns. Use of multiple small HF drivers instead of a more traditionally-used large format compression driver results in less distortion and a more extended HF response.
