Do not use hardware that isn’t load rated or that its’ rating is not enough to handle the 
system’s weight with a good safety factor (minimum 4:1). 

 

 

Suspended systems installation should only be carried out by qualified personnel. 

 

 

Always use adequate protective clothing and equipment to prevent possible injuries. 

 

 

Be  sure you understand all local and national regulations regarding equipment 
installation. 

 

PFA18sHP POWER AMPLIFIER 
AND DSP  

 

The PFA18sHP as all PFA series models, was designed to 
achieve a simple to use and deploy versatile system. The 

amplifier was  designed to power the  PFA18sHP  with 

2200W.  The  PFA18sHP, like all PFA  series models, is 

prepared to be completely plug’ n play, having already six 

pre-determined configurations that cover almost all 

situations. But if you’re not happy with any of those, there 

are also two available user defined configurations, which 

can be used to adapt the system to your needs using the 

NEXT-proaudio  SOUNDWARE

  software  and the supplied 

RS485 to USB converter.
