7  –  Volume  Control:  This  adjusts  the  overall  volume 
level  of  the  Principal  Grand  relative  to  the  main 
loudspeakers regard-less of whether the High-Level or 
the Line-Level inputs are used. 

8  –  Phase  Switch:  This  critical  switch  allows  for  the 
timing of the subwoofer to be in phase (in time) with 
the  main  loudspeakers.  The  correct  location  is  the 
position  that  produces  the  greatest  output  when 
combined  with  the  loudspeakers.  After  finding  this 
stronger  or  louder  position,  it  may  be  necessary  to 
lower the overall volume of the Principal Grand. 

9  –  On/Auto  Switch:  The  On-Position  places  the 
Principal  Grand  in  an  always  On-  position  while  the 
Auto-Position automati-cally places the Principal Grand 
into  standby  when  there  is  no  signal  for  15  minutes. 
While  in  the  Auto-Position  the  Principal  Grand  with 
return to On once signal is detected.
