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 andprocessors
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 beendamaged 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. Underno 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 notproperly 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 rigging, suspending or mounting. If there is any damage
or distortion to any mounting hardware do not proceed until any damaged hardware is repairedor replaced.
UNPACKINGAll Wharfedale Pro products are fully checked before leaving our factory. After unpacking pleaseinspect the cabinets for any physical damage Please retain the shipping carton if possible andinternal packing material incase the unit ever needs to be returned. Please check as soon as
possible that the unit is functioning. In the event of any damage please contact your dealerimmediately so that a written claim for damage can be made.

1About the WLA-1 Series
The science behind the new WLA-1 Hybrid Curvature Array is intense.
With 12” and 15” full-range elements and a breath-taking 21” subwoofer, the new WLA-1 system has been
engineered by IAG’s International R&D team to be highly versatile - making it perfect for touring and ﬁxed
installations.
The drivers inside are very special. Designed and Engineered by Wharfedale Pro UK and manufactured inEurope by Beyma, the full-range WLA-112 and WLA-115 elements use a coaxial design in combination withthe exclusive incredible EVO-Fold high frequency waveguide. This design provides consistent dispersion
coverage on both the horizontal and vertical planes with the sound radiating from one, singular andcoherent, source. Together with the dedicated FIR pre-sets library a ﬂatter phase front is granted allowing
outstanding audio quality performance.
This highly engineered solution combats issues that traditional constant curvature two way systems suﬀer
from due to physical spacing between the drive units.
Meanwhile, the WLA-121SUB uses a 21” Beyma driver with a 4.0” Quattro voice coil which results in themost extreme, but controllable ﬂying subwoofer in the Wharfedale Pro line up.
The WLA-1 system can easily be conﬁgured in 3 diﬀerent ways. As a sub-top pole mount, as a ﬂown arraywith the optional Common Fly Frame, or as a Horizontal system with the optional WLA-1 Link hardware.
Such versatility allows for users to deploy the system for multiple activities.
WLA-1 is a unique Hybrid Curvature Array. The science behind its development has been intense, but thisextreme engineering results in an extra-ordinary system with massive lows, consistent coverage andphase coherence.
