WPC

Features and Applications

Product Details WPC

WPC is the medium-format, three-way bi-amplified Wavefront Precision element for tours, festivals, live venues, sports facilities and large corporate or worship installations. It combines horn-loaded acoustics with a compact transport footprint. Martin Audio specifies 135 dB peak output, or 141 dB peak with crest factor 4.

As an example of system scale, the manufacturer describes a twelve-cabinet hang projecting beyond 60 metres for a 5000-seat audience. This is a system application example; coverage and output depend on the actual array, programme, venue and operating conditions.

Hybrid bass and independent MF/HF sections

Two 10-inch neodymium LF drivers are slot-loaded into short horns, with rear reflex loading extending the low-frequency response. The combination provides sensitivity, projection and bass impact from a medium-format cabinet, with greater LF control than a simple direct-radiating arrangement.

The midrange uses two 5-inch neodymium drivers on a dedicated horn for smooth vocal-band reproduction, high output and stable 100° horizontal directivity. Its acoustic assembly is physically separate from the HF horns.

Four 0.7-inch-exit neodymium compression drivers each feed their own HF horn. This distributes HF production across smaller drivers to reduce distortion in the most sensitive hearing range, extend the upper response and improve summation. Separate horn-loaded MF and HF sections maintain clarity and consistency at higher sound levels.

Deployment and environmental construction

Integral three-point rigging supports approved arrays of up to 16 enclosures. Side and rear handles assist lifting and splay-angle adjustment. This format supports both touring work and fixed installations where weight and truck space are important.

The current enclosure incorporates revised construction, coatings and metalwork. The published specification includes IP54, corrosion resistance, temperature and humidity protection, and UV stability for more demanding environments.

Scalable resolution and DISPLAY 3

System resolution is set by the number of enclosures assigned to each independently processed amplifier circuit. More circuits give DISPLAY finer control over audience coverage, frequency response and SPL consistency. Resolution can be chosen for the project budget, increased later by adding amplifiers, or varied between main arrays and auxiliary systems.

DISPLAY 3 combines mechanical angle selection with DSP optimisation against user-defined SPL and frequency-response targets. It models audience and non-audience areas, improves low-frequency control and provides greater flexibility in array length. Martin Audio describes its acoustic model as accurate to within ±1 dB of measured data. Hard Avoid can reduce energy at reflective ceilings, balcony edges or areas beyond the audience by up to 30 dB, subject to the system design.

Amplification, network control and identification

The array forms a complete system with dedicated external iKON Class D amplifiers. VU-NET transfers DISPLAY parameters over Ethernet and provides real-time control and monitoring. Dante supports digital audio distribution over CAT5 cabling, including longer cable routes and integration with other network-audio equipment.

Each amplifier output provides up to 1000 FIR taps at 48 kHz for wide-band optimisation. On current enclosures, an LED addressed through VU-NET identifies the cabinet circuit. This integrated design supports repeatable deployment and compatibility between inventories using the same system platform.
