WPL – Scalable Resolution Goes Further
-
With the launch of the Wavefront Precision Series (WPM and WPC) the concept of scalable resolution was born — harnessing the research and technology behind Martin Audio’s self-powered MLA® Series systems in a new line array format with external amplification.
-
Wavefront Precision Longbow (WPL) now brings this high performance, control and flexibility to large-scale touring and install applications. Designed as a complete system with external iKON multi-channel amplifiers, automated DISPLAY optimization software and VU-NET™ control platform, WPL provides financial accessibility to the top echelons of touring and install sound — from prestigious stadium concert and outdoor festivals, to high-specification arena and House of Worship installations.
All-Horn Advantage
-
WPL is a full-scale line array which is capable of exceptionally high output for its modest size and weight.
-
A three-way, bi-amped system, its very high output is achieved by utilizing Martin Audio’s trademark horn-loading technology across all frequency bands — increasing the acoustic output of the low frequency section, as well as the midrange and HF.

Scalable Resolution
-
With unmatched line array performance inherent in the acoustic design of WPL, scalable resolution offers versatility in the way a WPL array is powered and optimized. The greater the number of individually driven enclosures, the more precisely DISPLAY can fine-tune the array’s coverage, consistency and control within the venue. The advantages of higher resolution over a uniformly-driven line array are very significant — with front-to-rear frequency responses kept closely aligned and with greatly reduced output behind the array.
Bi-amped, with a passive mid/high crossover, a 12-enclosure array can be driven by either 3 x iK42 amplifiers (2-box resolution) or 6 x iK42 amplifiers (1-box resolution). With the number of amplifiers determined to suit the venue, the application and the budget, the commercial advantages of scalable resolution are clear:
-
Design systems to suit budget targets
-
Dynamic deployment within a venue or site where the main PA is driven with more amplifier channels than may be necessary for delays
-
Adaptable rental pricing based on event dynamics and clients’ resources
Display Optimisation
-
DISPLAY is an extremely powerful prediction and array configuration tool. Instead of using a standard geometric model, DISPLAY is based on an industry-leading acoustic model accurate to within ±1dB of measured data, and delivers unrivalled coverage consistency over the audience right from switch-on.
Amplification, DSP And Networking
-
WPL is designed as a complete system with dedicated, high-performance iKON multi-channel Class D amplifiers. For 1-box and 2-box resolution, the iK42 4-channel amplifier delivers very high power outputs and features high-speed Ethernet communication for system control and monitoring via Martin Audio’s VU-NET software, plus Dante™ digital audio networking. With the option to transmit digital audio over a single CAT5 cable, quality is maintained over long cable runs and integration with other devices in the sound system is straightforward.
Dual Hybrid Horn LF Section
-
Hybrid technology combines the efficiency and impact of a bass horn with the low frequency extension of a bass-reflex enclosure. With a typical efficiency improvement of 4dB compared to direct radiator low-end designs of competitors, a WPL array has a noticeable advantage over direct radiator arrays when projecting maximum LF output over distance.
Horn Loaded Midrange Section
-
The patented mid-range section is central to the signature sound and superb horizontal pattern control of WPL. Compared to direct radiator midrange designs of competitors, the horn design of WPL mid has the advantages of both greater output and superior horizontal pattern control which does not vary significantly with frequency.
High Frequency Section
-
Operating from 4kHz upwards, the HF section of the WPL utilizes 3 x 1” (25mm) exit neodymium compression drivers mounted on individual horns with true 90° horizontal constant directivity characteristics.
Rigging
FAST AND EASY RIGGING – DEPLOYMENT SPEED
-
Safety, simplicity and speed are essential aspects of a rigging system which the WPL three-point rigging system fully addresses. The rigging design allows for suspension of up to 24 enclosures, with DISPLAY software calculating the splay angles from 0°-7.5° needed to produce the desired vertical coverage. DISPLAY also determines the safe limits and tilt angle of an array and confirms compliance with specific safety standards, including BGV-C1, prior to deployment.
FRONT RIGGING POINTS
The front hinge points at the top of each WPL enclosure over-extend to ensure that there is plenty of ‘finger-room’ for riggers to pin enclosures together. As well safeguarding hands, this over-extension also gives useful latitude when connecting the lowermost box in an array to the uppermost box on a dolly which may not be on level ground, such as a festival site. As the hang is lowered, a second pin locks the hinge in place in its unextended position to minimise the gap between enclosures at the hinge point to just a few millimetres, ensuring vertical coverage consistency.
REAR RIGGING POINT
The rear rigging point sets the inter-cabinet splay angles determined by DISPLAY, and the design allows the angles to be easily set by a quick-release pin while enclosures are in their closed-up transport positions on the dolly. Once the uppermost enclosure on the dolly is attached to the array and the array is lifted, the dolly enclosures open up to the correct splay angles. A second pin locks each in place.
