CLEANING OF AMPLIFIER  

The fitted mesh filters ( foam) for the the cooling system should be reguarly cleaned to maximize 
the air flow into the unit.  

TRANSPORTATION 

KS  products  are  tools  for  daily  professional  use  and  are  correspondingly  robustly  manufactured. 
You should, however, be aware of these aspects of note: 
 
As with all types of electronic devices, condensation and moisture must be avoided i.e. when the 
speaker comes from a cold and humid truck and is brought into a warm venue, give the system as 
much time as possible to heat up to venue temperature before powering on.  
 
Of  course,  direct  exposure  to  liquids  is  never  safe  and  should  be  prevented  at  all  times.  The 
vibrations  of  a  transport  vehicle  are  safe  -  all  components  and  cabinetry  are  well  assembled, 
secured with screwed or bolted parts for extra strength where necessary.  
 
It has however been shown that train or airplane transport without further packaging creates un-
due stress on KS products. We recommend for such situations shock resistant flight cases.  
 
Significant  contamination  by  dust,  etc.  is  dangerous  for  Electronic  assemblies  as  it  may  cause  a 
short  circuit.  It  is  therefore  advisable,  that  the  devices  are  periodically  opened,  and  cleaned  out 
with compressed air.
