Once you have your system wired-up, follow the steps below:
• Set the mode switch to the ST 3 W position. Notice how the BAND INDI-
CATOR LED’s change showing the frequencies that are now under con-
trol by the associated GAIN or FREQUENCY knobs.
• Look for the illuminated L/M BAND INDICATOR LED over the first FRE-
QUENCY control. Now, use the first crossover FREQ on Channel 1 to
set the desired frequency dividing the Low and Mid frequencies. Now,
use the second crossover FREQ on Channel 1, indicated by the illuminat-
ed M/H LED, to set the desired frequency dividing the Mid and High fre-
quencies. Repeat the same procedure for the Channel 2.
• Look for the illuminated LOW BAND INDICATOR LED over the GAIN control. Now, adjust the first gain control
on Channel 1 to set the level of the Low frequency output. Look for the MID BAND INDICATOR LED over
Channel 1’s second GAIN control to adjust the MID output. Adjust the High output using Channels 1’s third
GAIN control designated by the HIGH BAND INDICATOR LED. Repeat the same procedure for Channel 2.
