EAW KF730 Manual De Usuario

 

For any faults that cannot be field-repaired as noted below, contact the EAW Service Department 
listed in Chapter 7 to determine the appropriate action. This applies to both warranty and non-
warranty faults. 
 

Because of the potential, serious consequences and liabilities due to faulty rigging, contact EAW 
to determine the appropriate service solution for any rigging hardware problems. 
 

Each KF730 and SB730 loudspeaker has an input panel, internal components and wiring, 
transducers, and an enclosure. Troubleshooting for various performance problems usually 
involves isolating the problem to one of these areas: 
 

1. Transducers 
2. Input panel, internal components, and wiring 
3. Enclosure and integral hardware 

 
If no problems can be traced to any of these items, look for problems with external electronics or 
cabling. Troubleshooting these items is beyond the scope of this manual.  
 
8.3.1 Transducers 

A faulty transducer will usually cause readily audible distortions or other unwanted noises. In 
other cases, they may stop functioning. Use your ears and test signals or other sound source to 
determine which one is at fault. Normally a faulty transducer requires service or replacement by 
EAW.  
 
8.3.2 

Faults with these items will usually cause transducers to stop working or possibly be intermittent. 
Check that audio signals pass from the input jacks to the transducer terminals. Many faults with 
this area can be field-repaired.  
  
8.3.3 Enclosures 

Enclosure problems, such as loose hardware, faulty joints, or other structural problems, will 
usually be heard as distinct buzzes, rattles, or other unwanted noises. To test for enclosure 
problems, use a sine wave signal manually swept on the LF sub-system. The input level should 
be no more than 6 dB below rated power (equals no more than 1/2 rated voltage). It may be 
possible to field-repair some enclosure problems.  
 

Visually inspect all rigging parts and enclosures each time they are used for wear, deformation, 
cracks, corrosion, damage, and any other condition that may affect load handling capability.   
 
DANGER: If there is any question about the integrity or capability of any rigging part to perform 
its intended function, immediately remove it from service for repair or replacement.
