Power Sources -- This Mackie product should be connected to a power supply only of the type described in these operation instructions or as marked on this Mackie product. Power Cord Protection -- Power supply cords should be routed so that they are not likely to be walked upon or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit this Mackie product. Object and Liquid Entry -- Care should be taken so that objects do not fall on, and liquids are not spilled into, this Mackie product. [. . . ] When connecting a balanced signal, be sure it's wired per AES (Audio Engineering Society) standards: XLR Hot (+) Pin 2 Cold (­) Pin 3 Shield (Ground) Pin 1 The THRU output connectors allow you to connect more than one SWA1501 to your system. Simply plug the signal source (i. e. , mixer output) into the first speaker's FULL RANGE INPUT jacks, and patch that speaker's THRU jacks to the next speaker's INPUT jacks, and so on, daisy-chaining multiple speakers. The THRU jack is wired straight from the FULL RANGE INPUT connector -- there is no electronic circuitry between -- so the signal coming out of the THRU jack is exactly the same as the signal going in. The HIGH PASS OUTPUT jacks provide a line-level signal of the frequencies above 120Hz that you connect to a pair of active speakers (or to a stereo amplifier powering a pair of passive speakers). See the diagrams on the rear panel of the SWA1501 for additional connection information. Balanced XLR Connectors PLACEMENT The SWA1501 subwoofer is designed to sit on the floor or on sturdy stands. A socket is provided on the top of the SWA1501 for mounting the Mackie SRM450 active speaker. Use the optional Mackie speaker mounting pole to mount the SRM450 on the SWA1501 (see Hookup Diagram on page 5). As with any powered components, protect the SWA1501s from exposure to moisture. If you are setting them up outdoors, make sure they are under cover if you expect rain. WARNING: The cabinet has no rigging points and is not suitable for rigging. NEVER attempt to suspend the SWA1501 by its handles. If connecting an unbalanced signal to the SWA1501 balanced input, be sure that the signal high (hot) connection is wired to Pin 2 and the unbalanced ground connection is wired to the low and the ground connections of the balanced input (Pins 3 and 1). If there are ground-loop problems, try connecting the unbalanced ground connection only to the input low connection (Pin 3), and leaving the input ground connection disconnected. There are also four male XLR connectors labeled THRU (FULL RANGE OUTPUT) and HIGH PASS (MID/HIGH FREQ) OUTPUT. These are also wired according to the AES standard. Unbalanced Male XLR Connector 6 AC POWER Be sure the SWA1501 is plugged into an outlet that is able to supply the correct voltage specified for your model. If the voltage should drop below 97% of the specified line voltage, the built-in amplifiers will no longer be able to supply rated power. (They will continue to operate down to 80% of the rated line voltage, but won't reach full power, resulting in lower headroom. ) Be sure the electrical service can supply enough amperage for all the components connected to it. We recommend that a stiff (robust) supply of AC power be used because the amplifiers place high current demands on the AC line. The more power that is available on the line, the louder the speakers will play and the more peak output power will be available for cleaner, punchier bass. A suspected problem of "poor bass performance" is often caused by a weak AC supply to the amplifiers. Never remove the ground pin on the power cord of the SWA1501 or any other component. If the thermal switch activates frequently, try turning down the level control a notch or two on the mixing console (or other signal source) or on the subwoofer itself to avoid overheating the amplifiers. If the temperature in the room is too high, it could cause the amplifier to overheat.
