The  LS4600  detects  circuit  faults  using  impedance  measurement  method.  In  general,  there  is  no  limitation  on  how  the 

external cabling to speakers or volume controller are run, ie. branching is allow and does not need end line resistors as well 

as speaker capacitor couplings.

LS4600  have  been  improve  all  accuracy.  It  is  recommended  that  periodical  manual  checking  or  setup  to  be  made  as 

connections may deteriorate over time and thus affecting overall impedance value.

Only 4 wire system is suitable for measurement. 3 wire system may cause undesirable result each time checking is being 

made due to the presence of volume controllers.
