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.
Inspect all mounting hardware before your line array is flown. If there is any damage or
distortionto any mounting hardware do not fly the array until any damaged hardware is
repaired or replaced. Only use Wharfedale Pro supplied Quick release Pins, contact your
Wharfedale Pro Distributor if any quick release pins are lost or damaged.

INTRODUCTION
The WLA-210X system keeps the same design philosophies as the acclaimed WLA-25
and WLA-28 systems from Wharfedale Pro. Portable, powerful and versatile line
array solutions which are ideal for both touring and fixed installation applications.
Each WLA-210X element uses a pair of custom 10” Wharfedale Pro high-power lowfre-
quency drivers, while the high frequencies are handled by a premium 3.0”
titanium diaphragm, neodymium magnet compression driver connected to 100° x
10° waveguide.
The waveguide exit extends nearly to the top and bottom of the enclosure to create
a continuous acoustical source - resulting in greatly reduced destructive interaction
within the array.
The WLA-210X element also features Passive and Bi-amp modes which allows for
complete system control. The bi-amp feature enables the system designer to select
the best amplification for each driver component within the array. Such control,
when used with external signal processing such as the Wharfedale Pro Versadrive
series, gives the engineer the ultimate in system fine tuning. This, in turn, leads to
the best audio output.
The WLA-210XSUB features dual 15” LF drivers with massive 4.0” voice coils.
Specifically created for use with WLA-210X, this subwoofer can be flown or ground
stacked easily as a result of its comprehensive rigging hardware.
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 the WLA-210X Common Fly frame, systems can be easily
configured as flying or ground stacked in multiple combinations.

WLA-210X - PASSIVE AND BI-AMP MODES
A switch on the WLA-210X input panels selects between either of two operating modes:
Passive mode (single amplifier) or Bi-amp mode (separate low and high frequency am-
plifiers). In passive mode, the internal crossovers of the WLA-210X loudspeakers divide
the audio signal into the separate frequency ranges for each driver. In Bi-amp mode
separate (discrete) amplifiers are used to power the low frequency and high frequency
drivers.
The Wharfedale Pro Versadrive series of signal processors are ideal for passive and
bi-amp mode operation and control.
Note - The WLA-210X subwoofer does not have an internal crossover. This function
must be supplied by external electronic devices such as a Wharfedale Pro Versadrive.
Its important to understand the advantages of the different operating modes. Wrong
operation will result in poor sound and, in the worst case, damage to the loudspeaker
drivers themselves.
Incorrect amplifier selection may result in loudspeaker damage
Incorrect wiring may result in loudspeaker damage
Incorrect crossover settings may result in loudspeaker damage

Arrays can be assembled using only WLA-210X line array elements or with
WLA-210XSUB Subwoofers at the top of the array. The WLA-210X Common Fly frame
supports up to 10 x WLA-210X elements and 1 x WLA-210XSUB OR up to 12 x WLA-210X
elements with a safety factor of 12.

FLEXIBLE ARRAYS
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.
OPTIMISED GROUND STACKING

The WLA-210X Common Fly frame is certified to hold a total weight (including
third party hardware) of 450kg. Up to 10 x WLA-210X and 1 x WLA-210XSUB
elements can be flown with a safety factor of 12.
Only use Wharfedale Pro fly frames. Ensure that only rated, certified hardware
such as tumbuckles, shackles and chains are used.
Ensure that all truss, structures and flying hardware are capable of suspending
the entire array, plus flying hardware, to a suitable safety factor.
Inspect all mounting hardware before your line array is flown. If there is any
damage or distortion to any mounting hardware do not fly the array until any
damaged hardware is repaired or replaced. Only use Wharfedale Pro supplied
quick release pins and contact your Wharfedale Pro distributor if any quick
release pins are lost or damaged.
