[. . . ] S218s PASSIVE SUBWOOFER USER'S MANUAL IMPORTANT SAFETY INSTRUCTIONS 1. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. PORTABLE CART WARNING Carts and stands - The Component should be used only with a cart or stand that is recommended by the manufacturer. [. . . ] Here are some additional placement tips to help overcome some typical room problems that might arise: · Avoid placing loudspeakers in the corners of a room. This increases the low frequency output and can cause the sound to be muddy and indistinct. This, too, increases the low frequency output, though not as much as corner placement. However, if you do need to reinforce the low frequencies, this is a good way to do it. A hollow stage can resonate at certain frequencies, causing peaks and dips in the frequency response of the room. It's better to place the loudspeakers on a sturdy table or stand designed to handle the weight of the cabinet(s). · · 1­ 2+ 2­ 1+ COLD HOT Speakon Connectors The 1/4" TS jack is wired as follows: Tip = Signal ("+" or hot) Sleeve = Ground ("­" or cold) SLEEVE SLEEVE TIP TIP TIP SLEEVE 1/4" TS Connectors 6 · Position the loudspeakers so the high-frequency drivers are 2 to 4 feet above ear level for the audience (make allowances for a standing/dancing in the aisles audience). High frequencies are highly directional and tend to be absorbed much easier than lower frequencies. By providing direct line-ofsight from the loudspeakers to the audience, you increase the overall brightness and intelligibility of the sound system. Highly reverberant rooms, like many gymnasiums and auditoriums, are a nightmare for sound system intelligibility. Multiple reflections off the hard walls, ceiling, and floor play havoc with the sound. If it appears that the S218s needs repair, you will be given a Service Request Number.
