Setup  procedure  for  the  Principal  Grand 
subwoofer 

 

1.

 

In order to prevent scratches and finger-prints we 

have  supplied  with  each  Principal Grand a pair of our 
special  cloth  gloves.  We  highly  recommend  using 
these throughout the entire setup process.          

2.

 

Connect the Principal Grand subwoofer using either 

a  pair  of  speaker  connections,  a  pair  of  Phono  (RCA) 
cables  for  stereo  or  a  single  LFE  cable  subwoofer 
cable.  In  each  case  we  recommend  that  you  discuss 
the  best  connection  scheme  with  your  retailer  and 
purchase the appropriate cable choice. 

3.

 

Connect  the  Principal  Grand  to  the  AC  power 

outlet. 

4.

 

Turn on the Master Power Switch. 

Note:

  If  the  power  LED  does  not  immediately 

illuminate, please check that the On/Auto switch is in 
the  Auto  position.  If  this  is  the  case,  it  will  be 
necessary  for  the  subwoofer  to  receive  and  audio 
signal  before  the  LED  will  illuminate.  For  the  setup 
procedure  you  may  want  to  place  this  switch  in  the 
On-Position and then return it to the Auto-Position for 
normal operation. 

5.

 

For  the  ideal  final  setup  as  well  as  the  most 

efficient use of setup time, please follow these simple 
dial-in instructions.
