Every genre of music is associated with a certain dynamic range, meaning the difference between the loudest and softest passages. The word “dynamic” is defined as “a force that stimulates change or progress within a system of process”. It defines how versatile a piece of music or a piece of gear behaves (musical instrument, amplifier, … Weiterlesen
When line-array loudspeaker systems are deployed in large venues, one issue that is most often debated is how to install subwoofers to adequately cover the entire audience. Should you keep the energy on the floor and deliver that tactile sense of bass to the crowd with a ground-stacked solution? Should you aim for more volume … Weiterlesen
You may remember from your science classes in school that the speed of sound is a constant, but this statement is entirely dependent on the material through which sound is propagating. Different medium transmit sound at very different speeds. So, let’s look at some typical materials that most people would encounter in indoor live sound … Weiterlesen
Subwoofers are great solutions to extend the low frequency performance of your PA system, and there are three aspects to consider carefully when setting up a subwoofer. In the following order. Subwoofer Placement If subwoofers are used in many portable and installed PA applications to enhance the overall listening and performance experience, their placement in … Weiterlesen
If you are familiar attending any type of live show, concert or performance using PA loudspeakers, you will most likely also agree that loudspeakers’ humming, hissing or buzzing noise can quickly ruin a performance. This article reviews each of the common causes of audible (and irritating) loudspeakers’ hum and hiss, and discusses effective strategies to … Weiterlesen
The history of the subwoofer is inextricably linked with the evolution of the full-range loudspeaker. In the mid-1950s, various manufacturers of hi-fi loudspeakers began to introduce compact, closed-box enclosures that featured long-throw woofers, and in the early 1970s a talented engineer working at Jensen, named James Novak, developed the equations describing a bass reflex (or … Weiterlesen
An auto mixer, or automatic microphone mixer, is a live sound-mixing tool that automatically reduces the volume level of a microphone’s audio signal when it is not used. This is particularly valuable when several microphones are open at the same time, reducing extraneous noise. In this article, we will describe how the Auto Mixer function … Weiterlesen
To start, let’s recall that the low frequency energy radiated from a conventional subwoofer is effectively omnidirectional below 200 Hz. This is because the directivity of a subwoofer is related to the ratio of its size to the length of the sound wave it produces. The length, or size, of the sound wave is inversely … Weiterlesen
Mindestens ebenso wichtig wie die horizontale Abdeckung ist die vertikale Abdeckung, die durch die vertikale Positionierung der Lautsprecher und den Abstand zum Publikum beeinflusst wird. Ein entscheidender Aspekt bei der Lautsprecherabdeckung ist die optimale Balance zwischen Lautsprecher-Distanz und -Lautstärke... Weiterlesen
Jeder Veranstaltungsort bietet spezielle Herausforderungen, wenn es um die Lautsprecherabdeckung geht. In einem Club mit einer niedrigen Decke ist zum Beispiel nicht genug Platz für ein vertikales Line Array, und bei Anwendungen im Außenbereich bringt die Tatsache, dass keine Wände vorhanden sind, ganz eigene Probleme mit sich...
