Page 4: Introduction
OPERATING MANUAL AND USER GUIDE Introduction The Wharfedale Pro WLA- is a mid format line array system with exceptional output, frequency response, directivity and throw capability. High tech transducers and enclosure design techniques give the WLA- a perfect power to size ratio. The WLA- achieves ultra high sensitivity with its fully horn-loaded architecture. A horn-loaded 12” LF is combined with three horn-loaded titanium compression drivers for the HF, generating huge SPL with maximum efficiency. The ultra high sensitivity of the WLA Series creates punishing level from even the most modest of power amplifiers, ensuring that your system can generate a huge SPL. -

Page 6: Splay Angles
OPERATING MANUAL AND USER GUIDE Splay Angles The WLA can be configured with several different splay angles. The splay angles determine the amount of overlap between individual units. This is used to determine the amount of summation, or “throw”, for separate sections of the array. As the splay angle between boxes increases the summation decreases but spectral variance due to interactions between elements is also decreased. -
Page 7: Air Absorption
WLA Series Air Absorption The high frequency performance of the medium and long throw sections of the line array will be limited by air absorption. As the distance from the source increases, the mid and high frequencies will be reduced. The amount of absorption at a given frequency is a function of pressure, temperature, and relative humidity. - Page 8 OPERATING MANUAL AND USER GUIDE Air Absorption Humidity (%)

Page 14: Wla-12 Dolly
OPERATING MANUAL AND USER GUIDE WLA-12 Dolly The WLA-12 Dolly should always be used when flying a WLA-12 line array system. Each WLA- Dolly will hold a single WLA- element. The WLA- Dolly helps to protect the WLA- element and aid the connection and flying process. -
Page 15: Installation
WLA Series Installation One Point Hang Procedure - Method 1 Attach a suitably rated shackle to the center spine of the fly frame. Use washers to ensure the shackle pin is centered on the spine. The connection point will depend on the splay angles used in your array and can be used to aim the array. - Page 16 OPERATING MANUAL AND USER GUIDE Method 1 & 2 Diagram THE WLA-12 AND FLY FRAME IS CERTIFIED TO HOLD A TOTAL WEIGHT (INCLUDING THIRD PARTY HARDWARE) OF 750KG. 12 ELEMENTS CAN BE FLOWN WITH A SAFETY FACTOR OF 5.7.
- Page 17 WLA Series Two Point Hang (Limited Space) Procedure - Method 3 Attach suitably rated shackles to the front and rear holes on the center spine of the fly frame. Use washers to ensure the shackle pins are centered on the spine.
