Operation Manual  rev 1.0.0

7. Crossovers

7. Crossovers

For optimal performance, the WA 15S has been designed to operate with White Acoustics WA 12F 
loudspeaker, where overall system control is achieved by using the White Acoustics WA 2.4X System Controller. 
The WA 2.4X has been factory preset to provide the recommended crossover points, delays and overall system 
balance. Please refer to the WA 2.4X Operation Manual for operation instructions. 

If you will be using an alternative loudspeaker management system from another manufacturer, please contact 
your distributor for the correct parameter settings, or refer to the recommended crossover points in the 
technical specifications section of this manual.

8. Equalisation

The WA 15S requires no equalisation or correction to overcome system limitations; equalisation is necessary 
only to compensate for difficult acoustic environments. Over-equalisation can reduce system headroom and 
introduce phase distortion, resulting in degraded sound. If equalisation is required, it should be applied gently 
and smoothly. Extreme equalization may be detrimental of overall sound quality.

9. Flying

The WA 15S incorporates convenient M10 flying points. The unit can be flown by utilising the EBS10 Eye Bolt 
Set, allowing for ease of installation and flexibility with the highest levels of safety. As with any flying system, 
safety can only be guaranteed when all precautions have been observed and procedures implemented 
correctly. 

The installation of this product must be carried out 
in conformity with local building codes and 
standards. If necessary, consult your local safety 
standards officer before installing any product. 
Alternatively, check any laws or bylaws. White 
Acoustics will not be held responsible for any 
damage caused by the improper installation of any 
flying gear or loudspeaker.
