How to mitigate Sound Propagation through Materials in Live Sound Settings
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 … Read More
Setting Subwoofer Level correctly in your PA System
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 … Read More
What Causes Loudspeaker Hum and Hiss and How to eliminate it
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 … Read More
How to correctly position multiple Subwoofers for Cardioid Deployment
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 … Read More
Practical Tips on Loudspeaker Placement for Live Sound (Part IV)
Perhaps even more important than horizontal coverage is vertical coverage, where elevation and distance become critical. A large part of proper loudspeaker coverage is finding a balance between loudspeaker distance and volume. To a certain extent, having loudspeakers farther from the audience makes it easier to achieve consistent coverage, assuming you have sufficiently powerful loudspeakers … Read More
Practical Tips on Loudspeaker Placement for Live Sound (Part III)
Every venue has its own specific set of coverage challenges. For instance, a club with a low ceiling will never provide enough vertical space to fly a line array system, and in outdoor sound reinforcement, the absence of walls brings its own set of constraints. Indoor Venues There are two categories of indoor venues: those … Read More
Practical Tips on Loudspeaker Placement for Live Sound (Part II)
There are a number of factors to consider when placing your loudspeakers to achieve optimal sound and performance. This four-part series aims to discuss a number of such challenges and to provide useful, practical tips to achieve great sound in any venue. While part 1 discussed loudspeakers’ radiation spaces and associated bass boosts, as well … Read More
Practical Tips on Loudspeaker Placement for Live Sound (Part I)
QSC loudspeakers are well-known to provide high-performance, accurate reproduction of audio sources in a wide range of applications. However, unlike a controlled studio environment, the real world provides myriad challenges to achieving sonically-pleasing results with QSC or any other loudspeaker. The conditions created by room shapes, ceiling heights, the presence of acoustically reflective or absorptive … Read More
QSC Directivity Matched Transition technology explained
In the history of professional audio, the introduction of QSC Directivity Matched Transition® (DMT™) technology has been one of those ‘lightbulb moment’ innovations that forever changed how audiences experience sound. In order to fully grasp its benefits, and why DMT is foundational to QSC loudspeaker design, let’s start with some fundamentals of the physics of … Read More
