For  more  information  on  fuse  ratings,  please  refer  to  Chapter  13 
“Specifications”. 

Caution!  This is the ONLY user accessible fuse. 

Never  replace  the  fuses  with  any  other  ratings  other  than  the  one 
specified on the rear panel. 

Always  ensure  your  200  MkII  is  disconnected  from  the  mains  supply
before attempting to change the mains fuse.

 

 

  Power Switch 

Set this switch DOWN to turn power ON.  Mute relay circuitry is employed in 
the 200 MkII so output is muted momentarily after the power switch is actuated.  
Set the switch UP to turn the unit OFF, at which time the speaker outputs will be 
disconnected.
