Make sure to have a firm grip, to protect yourself from injury and the instrument from damage. · Disconnect all cords coming from external devices. · Remove the unit from the speaker stand. 108d: Selection Important Notes In addition to the items listed under "USING THE UNIT SAFELY", please read and observe the following: Connection · Before making any connections, be sure all units in the system are OFF. Also be sure that all amplifier and mixer volume controls are at MINIMUM. · Before connecting SST/SSW/SSM Speakers to an external crossover read the specification chart carefully. Maintenance · For everyday cleaning wipe the unit with a soft, dry cloth or one that has been slightly dampened with water. To remove stubborn dirt, use a cloth impregnated with a mild, non-abrasive detergent. Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth. · Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation. Additional Precautions · To avoid disturbing your neighbors, try to keep the unit's volume at reasonable levels (especially when it is late at night). · To avoid possible breakdown, do not use the unit in a wet area, such as an area exposed to rain or other moisture. 3 Making Connections 1. Before you make connections, make sure that the power of all equipment is turned off. Also make sure that the volume controls on your amplifier and mixer are turned to the minimum position. 2. Use speaker cables to connect the output terminals of the amplifier to the inputs of the speakers. When connecting speakers, pay attention to the polarity (+/-) of the amplifier. The SST/SSW/SSM speakers have a nominal impedance of 8 ohms. Check the recommended load impedance of your amplifier. When connecting speakers in parallel, make sure that the polarity matches. Since the total impedance of all speakers will decrease if they are connected in parallel, check the recommended load impedance of your amplifier once again to make sure. In order to get the best sound quality, please use thick and sturdy speaker cables. Avoid using cheap cables, or shielded cables intended for use with a guitar. In order to achieve high-reliability connections, we recommend that you use Speakon® connectors (speaker connectors). When making Speakon® connections, refer to the network circuit diagram in the specifications. These speakers are equipped with self-recovering protection circuitry designed to guard the tweeters from excessively high input and abnormal signals. The circuit is tripped when the speaker is presented with excessive input, thus preventing sound output from the tweeter; this does not indicate a malfunction. In such instances, lower the amp volume; the tweeter function is restored automatically after 5­ 10 seconds. Contact a Roland Service Center if the speaker function does not recover properly. The Roland SST/SSW speakers are designed to allow multiple units to be combined to create highoutput spaker clusters. The SSW-351 speaker system can be driven with a single amp when using its built-in crossover network, or driven with a multi-amp system when an external crossover is used, and is also the ideal subwoofer system for use in conjunction with a SST-151/251. In order to take full advantage of its performance and to protect the speakers, please read the following explanations carefully. SST-151/251/SSM-151 Connect the inputs of the SST-151/251/SSM-151 directly to your amplifier. If you wish to add an additional SST151/251/SSM-151, connect it in parallel.

Using two power amps provides greater headroom when driving the speakers. Carefully read the specifications before connecting an external channel divider (crossover network). For the crossover frequency, we recommend frequencies between 100 Hz and 200 Hz. 5 Setting Up the SSM-151 When used as a stage floor monitor, the SSM-151 can be set at two different floor angles. 35° 55° When setting up monitor speakers, be sure to observe the following points in order to prevent the speakers from falling over (exercise caution particularly when using the 55degree setup, as the speakers may topple more easily in this orientation than when set up 35 degrees). * Do not sit or place feet on the speakers. * Do not place the speakers on unstable or inclined surfaces. * Do not use the speakers as steps.
