Roland ROLAND SPEAKER SYSTEM SST 151 251 SSW 351 SSM 151 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 Features 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 capaci
5. There are several ways in which an additional speaker can be connected to the SSW 351 1 Since the HIGH FREQ OUTPUT is routed through the internal crossover network a signal from which the low range has been cut will be sent to the connected speaker SSW 351 SST 151 251 EE Roland oO from the amplifier A superior quality in sound reproduction we recommend the use of a reverse polarity cable for this connection In this case the combined impedance will be 8 ohms The speakers can be driven by multiple amps very simply with the internal crossover network When driving the speakers with two power amps bi amping connect the speakers using the parallel input jacks SSW 351 SST 151 251 8 ohms Amplifier Amplifier Parallel input connection NEM NEM The volume balance between the subwoofers SSW 351 and full range speakers SST 151 251 and be adjusted with the power amp level settings Using two power amps provides greater headroom when driving the speakers The PARALLEL INPUTS can be used as an output to connect an auxiliary woofer or a full range speaker A full frequency range signal will be sent to the connected speaker SSW 351 SST 151 251 INTERNAL CROSSOVER Roland RANGE PARALLEL INPUT from the amplifier In this case the combined impedance will be 4 ohms A me
