Connecting the SUB120
Stereo Sub With Passive Satellites
Two SUB120’s can be used with any pair of passive or active monitors. Below is a typical system set using two SUB120’s with a mixer, stereo power amp and a pair of passive satellite loud 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

•Lower your mixer’s master outputs to all the way off.
•Connect the mixer’s left output to the left side SUB120’s LEFT PREAMP INPUT and the mixer’s right output to the right side SUB120’s RIGHT PREAMP LEVEL INPUT. Now connect the left SUB120’s LEFT PREAMP OUTPUT to the left side input of the power amp, and the right 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.
