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

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.

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.
