OWNER’S MANUAL
Thank you, and congratulations on your choice of the SST/SSW/SSM Speaker System.
Before using this unit, carefully read the sections entitled: “USING THE UNIT
SAFELY” (p. 2) and “IMPORTANT NOTES” (p. 3). These sections provide
important information concerning the proper operation of the unit. Additionally,
in order to feel assured that you have gained a good grasp of every feature
provided by your new unit, this manual should be read in its entirety. The
manual should be saved and kept on hand as a convenient reference.
Roland’s SST/SSW/SSM speaker systems, designed, developed, and
manufactured in the U.S.A., offer the ideal combination of excellent sound,
superb design, and outstanding value.
• The enclosures (except for the SSM-151) feature a trapezoidal design,
allowing them to be arrayed in radiating clusters.
• The metal speaker grills and 3/4" plywood cabinets are designed to
withstand the rigors of professional use.
• The tweeter features a built-in auto-reset protection circuit to prevent
problems from input overload before they start (not featured on the SSW-
351).
• The SSM-151 can be oriented at two different floor angles (35 and 55 degrees),
allowing selection of the most appropriate angle for your particular stage
environment.
• The crossover network components have been carefully selected to ensure
high input capacity and precise impedance characteristics.
• Speakon® NL4MP (speaker connectors) are featured to allow high-reliability
connections.
• Oversized steel carrying handles help to provide exceptional portability.
* Speakon® is a registered trademark of NEUTRIK.
