Verify that there is AC Mains voltage on the AC Mains input to the amplifier. 

 

If AC Mains voltage is present, verify that the fuse is not blown.  

 

If the fuse is not blown, try different presets to ensure there is no DSP issue. 

 

Verify that the correct fuse is inserted. Guidelines for this can be found earlier in this 
manual, and on the amplifier panel itself. 

If the problem has not been fixed, please contact your local P.Audio distributor for service 
information. 

NOTE: IF THE FUSE IS BLOWN REPLACE ONLY WITH THE SAME TYPE OF FUSE. THIS FUSE 
TYPE IS NOTED ON THE INPUT PANEL.  THERE IS ONLY AN INTERNAL FUSE.

PRODUCT SERVICE & WARRANTY 

 

 

There are NO user-serviceable parts inside the VIA Series amplifiers. The amplifier does NOT 
need to be removed in case of woofer service.. 

 

The VIA amplifier module MUST be serviced by a company authorized by P. Audio. 

 

Replacement of Components 

 

REPLACEMENT OF COMPONENTS MUST BE PERFORMED BY A QUALIFIED TECHNICIAN OR 
ONE KNOWLEDGABLE IN THE REPLACEMENT OF TRANSDUCER COMPONENTS! 

DO NOT ATTEMPT ANY REPAIRS UNLESS THE VIA SERIES AMPLIFIER HAS BEEN 
DISCONNECTED FROM THE AC MAINS SOURCE! 

 

In the event of 18” woofer failure, the woofer may be accessed by removing the front grille and then 
removing the woofer. This should be done by a qualified technician or contractor. There is no need 
to remove the amplifier panel in the event of a woofer failure.  

 

Use  extreme  care  when  handling  the  VIA  amplifier  modules.  The  components  are  fragile 
and the module must not be set down on the component side or damage will occur! 

Care  should  be  exercised  when  disconnecting  the  amplifier module  from  each  woofer.  Be  sure  to 
observe  the  wiring  polarity  of  both  woofers.    Ensure  that  both  the  woofers  are  wired  with  the 
correct polarity observed.  This is critical for correct functioning of the system.
