Thump18S Powered Subwoofer Introduction The Thump18S 1200W 18" Powered Subwoofer features a professional band-pass design that delivers class-leading output and deep, room-filling lows. Designed by the world's leader in portable live sound, the Thump18S provides ample power for high-output applications, bringing your Thump or SRM system to an entirely new level. A full set of professional input and output connections provide simple integration and sonic optimization of any system. Plus, there's ample system protection in place to protect your investment. With tons of power and a high-output/deep punch band-pass design, the Thump18S is the perfect subwoofer to complete your professional PA. Getting Started The following steps will help you set up the subwoofers quickly. 1. Make all initial connections with the power switches OFF on all equipment. Make sure the master volume, level, or gain controls are all the way down. 2. Connect the line-level outputs from the mixing console (or other signal source) to the XLR inputs on the rear panel of the Thump18S subwoofers. 3. Connect the high pass outputs from the Thump18S subwoofers to the inputs of powered loudspeakers (or to an amplifier powering passive loudspeakers). 4. Connect the supplied AC power cords to the IEC sockets on the rear panel of each subwoofer. Plug the other end into an AC outlet properly configured with the correct voltage as indicated below the IEC socket. 5. Turn the mixer (or other signal source) on. 6. Turn the subwoofers on. 7. Turn the loudspeakers on. 8. Start the signal source and raise the mixer's main L/R fader up until audio may be heard. 9. Adjust the master volume of the mixer to a comfortably loud listening level. Things to Remember: How to Use This Manual: After this introduction, a getting started guide will help you get things set up fast. The hookup diagrams show some typical setups, while the remaining sections provide details of the Thump18S subwoofer. This icon marks information that is critically important or unique to the subwoofer. For your own good, read and remember them. • Never listen to loud music for prolonged periods. Please see the Safety Instructions on page 2 for information on hearing protection. • As a general guide, the mixer (or other signal source) should be turned on first, Thump18S subwoofers next, and loudspeakers last. As such, the loudspeakers should also be turned off first, followed by the subwoofers, then the mixer. This will reduce the possibility of any turn-on or turn-off thumps and other noises generated by any upstream equipment from coming out of the speakers. • Save the shipping boxes and packing materials! You may need them someday. Besides, the cats will love playing in them and jumping out at you unexpectedly. Remember to pretend like you are surprised! • Save your sales receipt in a safe place. 4 Thump18S Powered Subwoofer
