Mackie SRT212 Altifalante ativo

SRT Series Professional Powered Loudspeakers are designed for real-world performance. The latest acoustic processing technology, powerful amplifiers, and ultra-versatile SRT Mix Control + SRT Connect app means easy setup, incredible sound, and unbeatable reliability.
The goal of Advanced Impulse™ DSP is to remove all the anomalies that loudspeakers and horns contribute to a signal, from “honkiness” or “squelch” to "mushy" low end, effectively making the drivers "invisible" and output nothing but perfect, clean sound. By more intelligently (and more thoroughly) employing the benefits of FIR filtering, Advanced Impulse DSP eliminates undesired acoustic anomalies across the entire dispersion zone (horizontal and vertical), as well as frequency range and time domain.
The custom horn within each SRT Series speaker was designed with the goal to bring out the very best from the HF transducer while maintaining the flattest response possible at the crossover point. The special design of this horn allows the compression driver to operate at near maximum efficiency. This means it gets louder and sounds better with less effort. The transition between the LF and HF is a symmetrical, flat response which is what helps make the incredibly smooth midrange in SRT Series speakers possible.
With the SRT Connect™ app available for iOS and Android® devices, you get complete control over everything and then some for up to 2 speakers simultaneously. Quickly access levels, EQ, meters, and configuration. Plus, you can save memory presets to streamline setup at your next gig.
When you link to another SRT Series loudspeaker, you get control over the entire system in the app, all in one view. No additional pairing or swapping back and forth on your device is required.
For an incredibly simple music playback system, you can stream music directly from any Bluetooth enabled device.
