Important: Consult the full User Guide for complete installation instructions and additional guidelines.

Attach the additional columns according to your needs. There are 2 columnar sections, one of which (the top-most section) is loaded with the loudspeakers. The other section can be used to determine the height of the loudspeakers. The loudspeakers should be placed so that they are relative to your audience’s ears for best results. For instance, if you are playing at the same level as the audience, you may wish to add the middle section so the loudspeakers are at ear-height. Or, if you are on a raised stage, you may wish to remove the middle spacer so the loudspeakers are closer to the audience on the floor. To attach a section, simply insert the protruding end into the cavity, aligning the internal connectors, and gently push until it snaps into place.
Connect your input and output devices, and then connect the subwoofer base to power.

Power on the unit using the Power Switch on the subwoofer base and start playing!

To disconnect, first power off the unit, then gently pull apart the sections.
