The WLA-1 Hybrid Curvature Array system…..is now…..ACTIVE.
The WLA-1A active system incorporates all the incredible hardware features of its passive brother – the WLA-1 System.
The EVO-Fold waveguides, the drivers created by Beyma in Europe and the Hybrid Curvature Array configuration are all included….but the new WLA-1A Active now brings powerful internal amplification and refined internal DSP processing to the party.
It has never been this easy to achieve stunning sonic results in a huge variety of venues.

Active Electronics
Around the back of WLA-112A and WLA-115A are all the connections and control interfaces needed for a tidy system.
Select between 8 DSP presets with FIR filters and control the system remotely with the RS485 network facility.
COAXIAL FULL RANGE
The 12” and 15” elements use coaxial drivers from Beyma – which are manufactured in Europe.
This coaxial design gives consistent coverage on both Horizontal and Vertical planes – while competitive traditional two-way line arrays do not have consistent coverage in one axis at least by design.
WLA-112A and WLA-115A coaxial design gives consistent coverage and is unique. (Well, except for our own Wharfedale Pro WLA-1 passive models)
WLA-1A System gives constant coverage on both Horizontal and Vertical planes
Competitive traditional constant curvature two way systems do not have consistent coverage in one axis at least by design.
HYBRID CURVATURE ARRAY
With a traditional 2-way array….arrays of 6 elements or more are simply not practical.
With the WLA-1 Hybrid Curvature design, arrays of up to 6 elements with 10:1 safety factor or up to 8 elements with 7:1 safety factor can be configured.
EVO-FOLD
EVO-Fold reduces the usual phase issues that traditional 2-way line arrays have due to them having the drive units physically some distance apart in the array. One specially-designed coaxial mid-high frequency driver is loaded to a unique EVO-Fold horn. The EVO-Fold horn combines a unique folded and manifold design. The most advanced FEM technology has been used to create this.
The high-mid energy exits produce a uniphasic sound in the widest range of frequencies. And visually, the detail of the EVO-Fold waveguide is a work of art.
SUBS – 21″ AND 18″ YES – REALLY!
The 21″ subwoofer driver is manufactured by Beyma in Europe.
Extreme features… for extreme (and controllable) sub sound pressure levels.
Combine the 21″ and the 18″ subs to get extended infrabass from the 21” and an extreme punch from the 18”. A combination to be experienced!
DEPLOYMENT CHOICES
1
Configure vertically and deploy as a ‘traditional’ flying array.
The optional WLA-1 Common Fly Frame ensures stability and that flying is easy.
2
Configure on the ground.
The optional SP-4 pole easily connects the 21″ or 18″ sub to the tops. Dual angle 35 mm pole sockets in the full range elements makes angle adjustments safe and easy.
3
Configure a horizontal flying array.
The optional WLA-1 Link hardware connects three elements of either WLA-112A or WLA-115A to create a 3 unit horizontal array with 60 H x 100 V dispersion
Software control
The network connection uses RS485 protocol and gives GUI control over the DSP parameters of each element in the array.
USB-RS485-RJ45
For easy connection to the computer, the optional USB-RS485-RJ45-MKII convertor can be used.

powercon ™
When interconnecting WLA series active line array elements, quality, certified power cabling should be used.
Wharfedale Pro distributors also can supply Neutrik ™ powerCON cables as an accessory for sale.
These certified AC interconnecting cables use genuine Neutrik ™ NAC3FCA and NAC3FCB connectors for the ultimate in reliability and safety.
2 meters in length allows for system configuration flexibility while keeping excess cabling to a minimum.
A tidy solution for any Wharfedale Pro Active Line Array.
TALK ABOUT ANGLES
WLA-1A introduces a new Hybrid concept giving variable angles of 0, 5, 10 and 15 degrees.
Easily adjusted using the integral rigging brackets.
Optional Common FLY FRAME
Configure the system how you like with the WLA-1 Common Fly Frame.
Subs at the top ? WLA-115A’s or WLA-112A’s. The Common Fly Frame supports all the different models in the WLA-1A series.
Note : WLA-1 Common Fly Frame supports up to 3 pcs of WLA-118SUB (A). WLA-118SUB (A) will not fly with WLA-121SUB (A).
