40 CLICK PRECISION 

ROTARY CONTROLS

These controls allow precise set-
ting of the electronic crossover and 
subsonic settings on the amplifier, 
thus taking the guesswork out of 
tuning your speakers.  Using a 
small slotted screwdriver make 
sure the controls are turned all the 
way to the left (counter clockwise).  
Refer to the chart and count the 
clicks (advancing one detent at 
a time clockwise) until you have 
reached the desired frequency.
 
This precise method of setting 
the crossover controls is available 
for the LPF, SUBSONIC and BASS 
FREQ features on this amplifier.
