Big bang for your bucks Mackie's Thump 215 powered speaker offers serious performance with a reasonable price tag. The Thump 215 uses a 2-channel 1400-watt amplifier to power its 15" woofer and 1" horn-loaded tweeter. Built-in time alignment and crossover circuitry result in maximum performance from the two drivers. To make sure the show will go on, Mackie incorporates thermal and power protection circuits so the drivers can't get pushed too hard. Connect and control The Thump 215 features a 2-channel input mixer with independent volume controls, so you won't need a separate mixer for small gigs. The mixer inputs can handle microphone, instrument, and line-level signals. A headphone-type 3.5mm TRS input lets you easily plug your portable player into this powered speaker. An XLR output provides a mixed signal so you can daisy-chain additional speakers for larger events. Versatile applications The Thump 215 's tough polypropylene cabinet includes four handles for portability and a perforated metal grille to protect the speaker. A mounting pole insert allows you to install this Thump speaker up on a tripod stand or on a speaker pole mounted over a sub, like a Mackie Thump 115S or 118S powered subwoofer. The speaker's angled design also lets you use it as a floor monitor for live performances.
