ADJUSTING THE HIGH CUT FREQUENCY

FREQUENCY HZ adjusts the level (be- tween 50 Hz and 200 Hz) at which the subwoofer begins passing frequen- cies to other speakers. This control’s setting depends on the low frequency capabilities of your satellite speakers (if used), speaker placement, and oth- er factors that affect bass perfor- mance.

To adjust the high cut frequency, first rotate FREQUENCY HZ clockwise until the music sounds too bass-heavy. Then rotate it counterclockwise until the bass sounds more natural.

If the mid-bass sounds natural but you want more low bass, rotate FREQUEN- CY HZ counterclockwise a little, then rotate VOLUME CONTROL clockwise by about the same amount. This in- creases low bass output without affect- ing the mid-bass output.

To reduce low bass output without af- fecting the mid-bass output equally, ro- tate FREQUENCY HZ clockwise and VOLUME CONTROL counterclockwise.

Note: Set FREQUENCY HZ to 200 Hz when using the PRO SW-200P with the Mini Home Theater Satellite Speakers (RadioShack Cat. Nos. 40- 4082/4083) and Mini Home Theater Center Speaker (Cat. No. 40-4084).

CARE AND

MAINTENANCE

Your Optimus PRO SW-200P 200- Watt Powered Subwoofer is an exam- ple of superior design and craftsman- ship. The following suggestions will help you care for your subwoofer so you can enjoy it for years.

•Keep the subwoofer dry. If it gets wet, wipe it dry immediately. Liq- uids can contain minerals that cor- rode electronic circuits.

•Use and store the subwoofer only in normal temperature environ- ments. Temperature extremes can shorten the life of electronic devices, and distort or melt plastic parts.

•Handle the subwoofer gently and carefully. Dropping it can damage circuit boards and cases and can cause the subwoofer to work improperly.

•Keep the subwoofer away from dust and dirt, which can cause premature wear of parts.

•Use only fresh batteries of the rec- ommended size and type. Old bat- teries can leak chemicals that can damage your subwoofer’s elec- tronic circuits.
