Page 3: Important Warnings & Safety Instructions
IMPORTANT WARNINGS & SAFETY INSTRUCTIONS • Read these instructions • Follow these instructions • Keep these instructions for future reference • Heed all warnings • Do not use this system near moisture or water • Clean only with a dry cloth • Install in accordance with these Wharfedale Pro operating instructions • Follow the manufacturer’s operating instructions for all peripheral devices such as amplifiers and processors • Do not install near heat sources such as radiators, heat registers, stoves or any other apparatus that produces heat (for example lighting systems and amplifiers) • Use only accessories specified or supplied by Wharfedale Pro • Do not use shielded microphone/instrument cables to connect amplifiers and speakers, use only approved speaker cables with proper connectors • Use caution with placement and operation of this speaker system, permanent hearing damage can be caused by prolonged exposure to excessive sound pressure levels • Refer all servicing to qualified professionals. Servicing is required when the loudspeaker has been damaged in any way, such as impact damage, liquid ingress or foreign object damage. In addition the loudspeaker should be referred to qualified service personnel if there is any kind of malfunction. Rigging, suspending and mounting should only be attempted by experience qualified professionals. Incorrect usage can result in damage to equipment and property, injury and even death. Under no circumstances should you attempt to rig, suspend or mount these speakers unless you are fully qualified and certified to do so by relevant local, state and national authorities. If you are not properly qualified or do not know of pertinent regulations consult qualified personnel for advice. Consult a structural engineer before suspending a speaker system and ensure that the total weight of your system can be held by the truss or mounting surface. -
Page 4: Introduction
INTRODUCTION Designed for the most demanding concert and installation audio professionals, the WLA-25 system sets new standards for astonishing acoustical performance in a compact size. Line arrays are increasingly employed in a wider range of venues and applications. Frequently these venues have height or sightline restrictions that limit the placement and size of the array. Rising fuel costs are putting pressure on touring system providers to downsize their transportation requirements. At the same time, client and audience expectations for audio performance has never been higher. To meet these needs, Wharfedale Pro embarked on a program to develop the most compact, highest output line array speaker system available. Each WLA-25 element uses a pair of high-power, 5” low-frequency drivers. Both cover low frequencies while only one extends into the mid range, thus maintaining horizontal dispersion control at a crossover. High frequencies are handled by a premium 1.75” diaphragm, neodymium compression driver, 100° x 10° multiple aperture diffraction waveguide. This creates a wide coverage with a superb stereo image and allows for more diverse placement. The waveguide exit extends nearly to the top and bottom of the enclosure to create a continuous acoustical source with minimal discontinuities between adjacent elements resulting in greatly reduced destructive interaction. Premium materials are used throughout the system. The enclosure is constructed of Baltic birch plywood and coated in an environmentally friendly, waterborne polymer finish that is field repairable. To keep the weight to a minimum and prevent rust, suspension fittings are made of aluminium. An elegantly simple 3-point suspension system combined with light weight, compact size and excellent handling ergonomics mean that a one person crew can easily deploy an array. With a choice of 3 different fly frame options suspension is easy, tidy and safe. The WLA-25 system is equally at home in the air or ground-stacked. -

Page 6: Splay Angles
SPLAY ANGLES The WLA can be configured with several different splay angles. The splay angles determine the amount of overlap between the individual units. This is used to determine the amount of summation or ‘throw’ for separate sections of the array. As the splay angle between boxes increases the summation decreases but the spectral variance due to interactions between the elements is also decreased. -
Page 7: Flexible Arrays
FLEXIBLE ARRAYS Arrays can be assembled using only WLA-25 line array modules or with WLA-25SUB Subwoofers at the top of the array. The WLA-25SUB Fly Frame allows for a WLA-25SUB subwoofer to be used at the top of the array. The WLA-25SUB Fly Frame supports up to 12 x WLA-25 modules and 1 x WLA-25SUB with a safety factor of 12. Arrays can be assembled using only WLA-25 line array modules. The smaller WLA-25 Fly Frame supports up to 12 x WLA-25 modules with a safety factor of 12. The WLA-25 Common Fly Frame allows for either WLA-25 elements or WLA-25SUB elements to be flown. -
Page 8: Optimised Ground Stacking
OPTIMISED GROUND STACKING WLA-25 rigging doubles up as an optimized ground stacking system, using the WLA-25SUB subwoofer as a base. Arrays of WLA-25 line array elements can be aimed downwards by as much as 10° to cover audience areas close to a stage, as well as upward by as much as 10° in order to better cover distant balcony seating areas. AIR ABSORPTION The high frequency performance of the medium and long throw sections of the line array will be limited by air absorption. As the distance from the source increases, the mid and high frequencies will be reduced. The amount of absorption at a given frequency is function of pressure, temperature and relative humidity. By far the most important factor is the relative humidity, although temperature does have a significant effect. To achieve minimal spectral variance across the coverage of the array, the groups of loudspeakers covering the middle to rear of the venue will require equalization to compensate for this effect. Air absorption is difficult to predict with any great accuracy, and in any case the relative humidity of the venue is likely to change when the audience arrive or the weather changes. It is important that the venue is monitored during the event as the equalization applied during the design stage with an empty venue may not be suitable during the event. As a general guide, boost above 8kHz for a long throw group of loudspeakers and 12kHz for a medium throw group of loudspeakers. The chart overleaf shows attenuation in dB/m for a given frequency and humidity. It is important to note that the effects of air attenuation are linear, unlike the level of attenuation from distance from the inverse square law. For example, at 100m a source would be 40dB down compared to it’s SPL at 1m. Assuming 50% relative humidity and 20° the level at 10kHz will be an additional 16dB below this (approximately 56dB down). -
Page 9: Air Absorption
AIR ABSORPTION The WLA-25 has internal crossovers. The internal crossover of the WLA-25 loudspeaker divides the audio signal into the separate frequency ranges for each driver. The WLA-25SUB subwoofers do not have internal crossovers. This function must be supplied by external electronic devices such as the Wharfedale Pro Versadrive series or LMX-204. -
