At the heart of the WLA-210X are 2 x 10″ custom Wharfedale Pro LF drivers. These have been meticulously designed to ensure high efficiency and high power handling. The HF Compression driver is also custom made by Wharfedale Pro. Using a neodymium magnet and a 3.0″ voice coil, this compression driver is coupled to a 100° x 10° waveguide. These custom designed transducers are what give a WLA-210X system its incredible sound and power handling capacity.
OPTIMISED GROUND STACKING
WLA-210X rigging doubles up as an optimised ground stacking system, using the WLA-210XSUB subwoofer as a base. Arrays of WLA-210X 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.
BI-AMP & PASSIVE MODES
In BI-AMP mode, two power amplifier channels can be used, one for each section of the loudspeaker (HF compression driver and LF transducers). DSP (Digital signal processing) is used to separate the audio signal into specific frequency bands for each amplifier channel, powering only the corresponding driver section inside the loudspeaker. This gives you the advantage of being able to select the optimal power specifications and use independent limiter and EQ settings for each driver, resulting in more granular system control and a safer, more efficient, and protected system.
In PASSIVE mode, a single amplifier channel can be used to power all drivers inside the loudspeaker. The full frequency range is put into the loudspeaker and the loudspeakers’ internal passive crossover separates the frequencies, delivering the right frequencies to the right driver. In the example of a 2-way passive loudspeaker, this means that the single amplifier channel is powering both the HF compression driver and the LF transducers. The internal crossover takes care of both the frequency and power separation.
The Wharfedale Pro Preset Library includes factory presets for both BI-AMP and PASSIVE modes, these must be used for optimal loudspeaker performance and protection.
AMPS & DSP
A Versadrive DSP (such as SC-48 FIR) or a DP-N series amplifier with internal FIR filtering is highly recommended to get the most from the system. Phase, EQ and filtering should be applied and this way, the physics of the system can be truly optimised – delivering that sub-bass, power and clarity that this system can deliver.
