Connection Details:

All connections are via rubber 
grommets on the sides of the box 
and onto screw terminals located 
on the printed circuit board.

 

• Caution:

When using the mic level outputs it is 
recommended that the screen chassis 
links be left in place to reduce the 
possibility of hum pickup. However, care 
must be taken when using both mic 
level outputs to separate amplifiers not 
to create earth loops within the system. 
To prevent this from happening it may 
be necessary to remove just one of the 
screen chassis links and leave the other 
intact.
