Incredible Features
1600W Class-D AmplifiersSRT Series Loudspeakers feature their most rock-solid amplifier platform ever for better performance across the board than any other loudspeaker in its class. Incredibly efficient power along with sophisticated protection and monitoring make SRT the ultimate workhorse.
Custom SYM-X HornThe custom designed Sym-X horn combined with a custom high-frequency driver provides an almost razor flat response (within +/- .5 dB), and that carries through the crossover point to the woofer for midrange that sounds clear and precise even at high SPL.
Advanced Impulse DSP-Proprietary Acoustic TuningAfter years of tweaking settings and lugging around test equipment has paid off, and you get to experience the benefits. Thanks to Advanced Impulse DSP, muddy midrange, harsh highs, and sloppy bass simply do not exist with these speakers. Not only does SRT sound incredible directly in front of them on-axis, they sound just as good all the way to the edge of their coverage unlike other standard loudspeakers.
SRT Mix Control - 4 Channel Digital Mixer With BluetoothFeaturing a full-colour display, settings and adjustments are clear and easy to see. The main window displays input and output levels. Easily dive into channel and system settings for current voicing, EQ, alignment delay settings, and more all at a glance. Dowload the SRT Connect app for complete wireless control from your phone with Bluetooth connectivity to stream to a pair of SRT Series speakers for an incredibly quick and easy music playback rig.
Application Based Voicing ModesAdapting your system to your specific needs and where it is all happening is vital to getting the best sound possible. Within SRT Mix Control, you get unique voicing modes that will each apply a preset response curve making the speaker optimized for that use. This provides even more optimization which can all be controlled directly on the speaker using the SRT Connect app.
Wireless LinkingIf you want to get music playing through your system quickly or make on-the-fly adjustments to your loudspeakers, you can do this easily by pairing your two SRT Series speakers together and control and stream music to them from your phone. The can works as a stereo L/R or be split up as a dual zone system with individual level controls.
Transparent System Protection & MonitoringSRT Series Loudspeakers utilize a complex combination of input limiting, multi-band compression, temperature monitoring and signal analysis to protect the amplifier and tranducers.
Advanced Impulse DSP Module
Nothing But PerfectMackie’s filtering technology is not your usual speaker processing. The aim of the 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), along with frequency range and time domain.
The main way this is achieved is by measuring the negative frequency response and time domain impacts that each transducer and horn in the system introduces, on and off axis, 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
Unique DesignThe custom horn inside each SRT Series speaker was designed with the aim of bringing out the very best from the HF transducer while maintaining the flattest response possible at the crossover point.
The unique 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.
Transparent System Protection
Best Possible SoundOther loudspeakers include 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, 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
Rapid SetupWith the SRT Connect™ app available for iOS and Android® devices, you get total control over everything and then some for up to 2 speakers at the same time. Quickly access levels, EQ, meters, and configuration. You can also save memory presets for a quick 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 easy music playback system, you can stream music directly from any Bluetooth enabled device.
