• 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... -
Page 4: Introduction
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 1.7” 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. -

Page 6: Splay Angles
Smaller splay angles provide higher summation to cover more distant seating and bleachers. Larger splay angles provide lower summation with reduced spectral variance for close seating. Used correctly this can provide even coverage over long distances. Each group of loudspeakers with different splay angle will require a separate channel of amplification and different EQ settings. This is due to the different summation effects by differing splay angles. LEVEL TAPERING Tapering the level of enclosures has a beam steering effect which can be used in the conjunction with angular separation between elements. The beam will be steered away from the ‘on-axis’ centre line of array toward the cabs being driven at the highest level. The extent of the beam steering effect depends on the length of the array and the level difference between the top and the bottom of the array. This technique allows you to further tailor the vertical coverage to differently shaped venues, reducing the level variance between the front and rear of the venue. Ideally the level of each enclosure is tapered gradually (e.g. 0.5dB or 1dB per element). This means you will require an amplifier channel per element in passive mode, or two amplifier channels per element in bi-amp mode. Groups of elements can be tapered in pairs or more, although a more gradual taper will give you smoother vertical pattern control. WLA-25&25SUB MANUAL.indd 2017-6-20 9:23:17... -
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.

Page 8: Optimised Ground Stacking
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.
