• Lower your mixer’s master outputs to all the way off.
• Connect the mixer’s left output to the SUB120’s LEFT PREAMP LEVEL INPUT and the mixer’s right out-
put to the SUB120’s RIGHT PREAMP LEVEL INPUT. Now connect the SUB120’s LEFT PREAMP
LEVEL OUTPUT to the left side input of the power amp, and the SUB120’s RIGHT PREAMP LEVEL
OUTPUT to the right side input of the power amp. Connect a speaker wire from the left output of your
power amp to your left satellite, and then, connect a speaker wire from the right output of your power
amp to your right satellite.
• Now adjust the SWEEP control to the desired frequency. Consult your studio monitors owner’s manual
for a recommended crossover point. You can also use your ears by adjusting the SWEEP control to the
frequency that sounds good to you. A good place to start is about 70 Hz.
• Now set the level of your power amp up to the normal operating level. Run an audio signal (like some
music from a CD) through your mixer and raise the level to a comfortable listening level. Now slowly
raise the SUB120 volume control and listen to the low frequency output. Adjust the SUB120 to the level
of low frequency output that you like. Now, when you raise and lower your mixer’s output, the SUB120
and satellites will track at the same relative volume.
Mono Sub With Passive Satellites Using Line Inputs
The SUB120 can be operated using line level inputs and outputs. When using the SUB120 at line level, the full
range signal is maintained at the outputs. Below is a typical system set up using the SUB120 with a mixer, stereo
power amp and a pair of passive satellite loudspeakers. The SUB120’s inputs and outputs utilize industry stan-
dard RCA connectors. For a detailed wiring diagram, see the section SUB120 Connections on page 17. Follow
the steps below the diagram to set up your system.
