The Mackie SRT215 powered loudspeaker offers premium sound for working musicians, DJs, and venues alike. Its 1600-watt Class D amplifier packs reliable, consistent performance in a lightweight package, and its custom high-efficiency transducers ensure top-notch sound. Everyone within earshot will experience outstanding audio quality, thanks to the SRT215's Advanced Impulse DSP, while a dedicated processing module guards against system overloads with the utmost in transparency. This state-of-the-art PA speaker includes a flexible 4-channel digital mixer with application-specific factory presets and an easy-to-read full-color display for simplified setup; the SRT215 also includes a dual-angled cabinet for versatile configuration options. Wireless connectivity and control and Bluetooth streaming capabilities round out the SRT215's robust feature set.

Robust LF driver and custom Sym-X Horn HF driver combine for incredible performance

The SRT215 may pump out 1600 watts of reliable Class D power, but the secret to its great sound is in the drivers. The SRT215 is loaded with a 15-inch woofer and a custom Sym-X Horn tweeter. Both drivers have high-performance transducers that minimize distortion and increase output for unparalleled clarity and accuracy. For optimal efficiency, the horn-loading frequency is set below the tweeter's low-frequency capability. You'll enjoy the symmetrical, flat response at the crossover point for smooth transitions. Simply put, the SRT215 is versatile enough to handle any application you can imagine.

SRT Mix Control built-in 4-channel digital mixer with Bluetooth

On the back panel of the Mackie SRT215, you'll find a 4-channel digital mixer with a high-contrast full-color display. Dual independent channels support mic, line, and instrument signals while a dedicated 1/8-inch stereo auxiliary channel provides seamless audio playback between performers. It also has Bluetooth connectivity, so you can easily stream music when you're offstage. Single-knob control gives you quick access to all parameters, including levels, EQ, voicing modes, and up to 10 user presets. A built-in system lock and 4-digit pin ensure that nobody can tamper with your settings while you're not looking. You also get a screensaver, along with a dimmer and contrast control.

Advanced Impulse DSP delivers ultra-accurate sound reproduction

The SRT215 is equipped with Mackie's Advanced Impulse DSP, a proprietary acoustic tuning mechanism uses Digital Signal Processing (DSP) to great effect. Precisely placed crossover points work together with time-aligned transducers to create symmetrical and detailed reproduction. To simplify, Advanced Impulse DSP allows the SRT215 to provide crystal-clear audio reproduction across the whole dispersion zone. When you run audio through the SRT215, the whole room is your sweet spot.

Transparent system protection guards against excessive levels

As the seasoned live sound experts here at Music Experience will tell you, unpredictable level spikes are a fact of life. The Mackie SRT215 takes this into account, providing you with a dedicated processing module that monitors your amplifier in real time to guard against excessive levels. It's extremely transparent — instead of sacrificing your overall output to prevent overloads, the SRT215 uses multiband compression to attenuate specific frequency ranges. What's more, input limiting tames extra-hot sources before they cause issues. You also get Power Factor Correction for rock-solid operation in venues with unstable power.

SRT Connect app gives you complete wireless control

Controlling your SRT215 is incredibly easy, thanks to the Mackie SRT Connect app for smartphones and tablets. Simply open the app, pair your device with your loudspeaker, and you're ready to get to work. You can cycle through each channel, tweak the graphic EQ, select from three reverb modes, and use the Mixer view to monitor the level of each channel on a single screen. The SRT Connect app also offers built-in EQ modes that tailor your speaker to fit any application. You can also link two SRTs wirelessly, in either stereo or dual-zone configurations, with up to 100 meters of range between linked loudspeakers.

No More Excuses - A Loudspeaker Upgrade That Makes Sense

If you've been debating an upgrade to your sound system, the time has come to ditch those dusty old speakers from the 80's. With the SRT Series, experiencing incredible sound, cutting-edge performance, and reliability is a no-brainer.

Advanced Impulse™ DSP Module

What does it do for me? Mackie’s filtering technology is not your typical speaker processing. The goal of our 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.Mackie Advanced Impulse DSP.

How It's Done

The main way this is accomplished is by measuring the negative frequency response and time domain impacts that each transducer and horn in the system introduces – on axis as well as off – and reversing/correcting for those anomalies before the signal hits the speaker. The result is the output from the speaker is fully corrected for flat, clear, time-aligned, and smooth sound throughout the entire time, space, and response domains.

SYM-X™ Horn

The custom horn within each loudspeaker 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. Surprise surprise... we nailed it. 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 possible.

Transparent System Protection

Other loudspeakers feature some sort of protection and limiting to help them squeeze a dB or two out of the speaker. This is almost always at the expense of sound quality and is commonly experienced as diminished bass response and the "pumping" sound of the internal limiter having a bad day. When operating at very high levels (ears beware), the processor-controlled system monitoring analyzes the audio signal and identifies the problem areas, then dynamically applies multi-band compression to those specific frequencies rather than lowering the overall output. This keeps your levels where you want them and maintains the sound quality you expect.

Wireless Control & Streaming

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.
