•
Set the mode switch to the ST 2 W position. Notice
how the BAND INDICATOR LED’s change showing
the frequencies that are now under control by the
associated GAIN or FREQUENCY knobs.
•
Use the first crossover on Channel 1 and 2 to set the
desired frequency.
•
Adjust Gain number 1 on Channel 1 and 2 for the
Low frequency outputs.
•
Adjust Gain number 3 on Channel 1 and 2 for the High frequency outputs.
