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.

Features

  • 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

Benefits

  • 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

Applications

  • 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.

Architectural Specs

Wavefront Precision WPC

The loudspeaker shall be a bi-amplified, vertically-arrayable three-way system powered by a dedicated controller amplifier. Its transducers shall consist of two 10” low frequency drivers, two 5” midrange drivers each coupled to a constant-directivity midrange horn, and four 0.7” exit compression drivers each coupled to a constant-directivity high frequency horn. Crossover frequencies shall be 440Hz active, 4.4kHz passive.

The loudspeaker shall have 100° horizontal dispersion and 10° vertical dispersion. Vertical dispersion of the complete array shall be determined by a combination of the splay angles between adjacent enclosures and dedicated array control software. The on-axis frequency response shall be 65Hz-18kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 135dB peak at 1 metre. Power handling shall be 500W AES, 2000W peak for the LF section and 220W AES, 880W peak for the combined mid and HF section.

The rear of the enclosure connector panel shall be fitted with two NL4 type connectors.

The loudspeaker enclosure shall be constructed from multi-laminate birch and poplar ply and finished with a durable textured black paint. The drivers shall be protected by a perforated steel grille with a scrim cloth backing and the enclosure shall incorporate a pocket handle in each side panel and two rear grip handles. The enclosure shall additionally incorporate an integral three-point rigging system to assemble an array of up to 16 enclosures suspended from a dedicated flying frame.

Dimensions (W x H x D) shall be 772mm x 319mm x 421mm (30.4in x 12.6in x 16.6in). Weight shall be 35kg (77.1lbs).

The loudspeaker shall be the Martin Audio Wavefront Precision WPC.
