PA-600 AMPLIFIER OPERATION

Stereo Mode:

Bridge Mono  Mode:

The  following  diagrams  are  excerpts  from  the 
system  block  diagrams  and  are  intended  to 
provide  a  simplified  view  of  the  operating  modes 
of the amplifier. 

BRIDGE  MONO  SWITCH:  This  switch  connects 
the  channels  to  work  together  for  more  power 
output.  With  the  switch  in  "MONO"  Mode  the 
amplifier  is  in  the  Bridge  Mono  Mode.  In    the   
Bridge  Mono  Mode, connect input to  Channel  1 
(Channel  2's  inputs  are  disconnected).  Both  amp 
channel  are  internally  bridged  together  to  create  a 
single-channel amplifier of increased output power. 

Use  the  two  red  BINDING  POSTS  (labeled 
" M o n o / B i a m p " )   o r   p i n s   1 + / 2 +   o f   t h e
