Connecting the SUB120
Mono Sub With Active Satellites
If you have active studio monitors, installation is easy through the SUB120’s LINE LEVEL inputs and outputs. Below is a typical system set up using the SUB120 with a mixer and a pair of active satellite speakers. The SUB120’s input and outputs utilize industry standard RCA connectors. For a detailed wiring diagram, see the section SUB120 Connections on page 15. Follow the steps below the diagram to set up your system.

SUB120 120 WATT 10" SUBWOOFER
•Lower your mixer’s master outputs to all the way off.
•Connect the mixer’s left output to the SUB120’s LEFT LINE INPUT and the mixer’s right output to the SUB120’s RIGHT LINE INPUT. Now connect the SUB120’s LEFT LINE OUTPUT to the input of the left powered satellite, and the SUB120’s RIGHT LINE OUTPUT to the input of the right powered 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.
