Setup

1. Place the SW12 on the floor near your main speakers, with nothing blocking the speaker face.
2. Power off all equipment and use an RCA cable to connect the sub output of your digital processor or amplifier, or the LFE output of your decoder, to the SW12's Line In / LFE input.
3. Plug in the SW12, turn on the source and amplifier first, then turn on the subwoofer.

Tuning

1. Start with the SW12 volume low and raise it gradually until the bass blends with the main speakers.
2. Adjust the phase within 0°–180° and choose the setting that gives the tightest, clearest bass at your seat.
3. When singing karaoke, keep the bass at a moderate level so it doesn't overpower the vocals.

Care

• Wipe the cabinet with a soft, dry cloth; don't use harsh cleaning chemicals.
• Place the speaker in a dry spot away from direct sunlight and heat sources.
• Turn off and unplug when not in use for long periods.
