Mono Sub With Passive Satellites Using Speaker Inputs
The SUB120 is a perfect addition to any near-field monitoring system where enhanced low-end is desired. Below
is a typical system set using the SUB120 with a mixer, amplifier and a pair of passive satellite speakers. In this
mode, the signal sent to the satellite is high-passed at 100Hz. The SUB120’s input and outputs utilize industry
standard speaker connectors. Follow the steps below the diagram to set up your system.
• Lower your mixer’s master outputs to all the way off.
• Connect the mixer’s left output to the left input of your power amp and the mixer’s right output to the right
input of your power amp. Now, using standard speaker cable, connect the power amp’s left speaker out-
put to the SUB120’s LEFT SPEAKER INPUT and the power amp’s right speaker output to the SUB120’s
RIGHT SPEAKER INPUT. To complete the connections, run a cable from the SUB120’s LEFT SPEAK-
ER OUTPUT to the left satellite and from the RIGHT SPEAKER OUTPUT to the right satellite speaker.
• 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.
