[. . . ] If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. Only use attachments/accessories specified by the manufacturer. Unplug this apparatus during lightning storms or when unused for long periods of time. [. . . ] This product makes it easy to setup a high quality sound system quickly with a minimum amount of cables and external electronics. The additional speaker output is useful to connect either a second subwoofer (e. g. Zx1, Sx80, or Sx300). System Features ­ SB2A · Integrated Amplifier with 350W for Internal Woofer and 350W for Optional External Speaker · Selectable Speakon® Output for Additional Sub or Fullrange System · XLR and 1/4" TRS Input Connector · XLR Parallel Output Connector · LED Indicators for Signal and Limit · Lockable IEC Mains Connector · Easy Fullrange System Setup with Optional Zx1, Sx80 or Sx300 4 SAFETY FIRST When setting up, installing and using the Electro-Voice SB2A speaker system, there are a number of precautions that you should follow: When Electro-Voice SB2A speakers are used for portable applications they should be positioned directly on the floor. Please make sure that the floor or stage is solid and secure. Electro-Voice SB2A speakers include a 1-3/8 inch pole mount, which allows a smaller full-range loudspeaker to be elevated on top. WARNING: The SB2A is very lightweight and has a small footprint. Do not attempt to pole-mount a speaker system larger than ZX1 or Sx80 on the SB2A Route cables and position the SB2A so that performers, production crew and audience members will not trip over the cabinet or cables and pull the speaker system over. Secure cables with wire ties or tape whenever possible. If you intend to hang or fly the SB2A (for example in combination with Sx300), only do so safely with the correct hardware and accessories MB200 and MB300. Consult the Sx Series Rigging Manual (p/n 534780) for instructions. WARNING: Suspending any object is potentially dangerous and should only be attempted by individuals who have a thorough knowledge of the techniques and regulations of rigging objects overhead. Electro-Voice strongly recommends that SB2A speakers be suspended taking into account all current national, federal, state and local regulations. It is the responsibility of the installer to ensure that SB2A speakers are safely installed in accordance with all such regulations. If SB2A speakers are suspended, Electro-Voice® strongly recommends that the system be inspected at least once a year. If any sign of weakness or damage is detected, remedial action should be taken immediately. For further information regarding the necessary hardware kits and their use please consult the accessory documentation. There are data sheets for each EV Suspension and Array Kit that should also be consulted prior to suspending speakers. Electro-Voice does not recommend use of SB2A speakers outdoors without protection from rain or in high moisture environments. Electro-Voice SB2A loudspeakers are easily capable of generating sound pressure levels sufficient to cause permanent hearing damage to anyone within normal coverage distance. Caution should be taken to avoid prolonged exposure to sound pressure levels exceeding 90 dB. CAUTION: This appliance has no user-serviceable parts inside. Leave any servicing and maintenance to qualified service technicians only. Make connections to these terminals as described in the owner's manual. 5 SYSTEM SETUP To get the SB2A into operation as quickly as possible, please observe the following steps and precautions: · Plug the 3-terminal IEC-standard AC cable into a grounded line receptacle.
