Early 50’s audio researchers made key findings related to the human perception of sound, reflections and echoes. Their fundamental work is not only interesting, but can be used to our advantage in audio mixing and live sound applications. Let’s go through details and further insights here. To start with, our hearing mechanism integrates sound intensities … Read More
Have you ever had an experience at a live event, like a concert or a show, where the sound seemed thin, lacking in punch and dynamics, or with a disturbing phasing effect as you moved around? If the sound system was comprised of a number of loudspeakers either stacked or placed side by side, or … Read More

As surprising as it may sound, your audio equipment is … Read More
You will have noticed that in a large number of live events, sound engineers place subwoofers close together either on the floor, on the side of the stage, or at the top of the line-array rig. Are there any benefits in doing so, and what exactly happens? Before exploring the answer, let’s first recall some … Read More
Every so often, a new technology comes along that causes you to reconsider the concepts you knew and change the way you specify or design systems. A few years ago, QSC introduced a new amplifier platform of four-channel DSP power amplifiers featuring Flexible Amplifier Summing Technology™ (FAST). Today this technology can be found in PLD, … Read More
