    line arrays
    Jeff Berryman 04/09 01:57 PM,
    This is a discussion of line array high-frequency output capability, and what it might mean to you. The specific quantity we’re looking at is the frequency response at maximum output power for all drivers. This is the maximum acoustic output of the array as a function of frequency. I will call it the power-bandwidth response. Here’s a question: what power bandwidth must line array elements have in order to deliver a flat frequency response to audience seats? Because of the… View this story

    This article is provided by Rane Corporation.   You may have heard it said that equalizers are nothing more than glorified tone controls. That’s pretty accurate and helps explain their usefulness and importance. Simply put, equalizers allow you to change the tonal balance of whatever you are controlling. You can increase (boost) or decrease (cut) on a band-by-band basis just the desired frequencies. Equalizers come in all different sizes and shapes, varying greatly in design and complexity. Select from a… View this story

    This article is provided by Commercial Integrator   Let’s face it: true commercial systems integrators’ reputations have taken a hit by clients’ bad experiences with not-so-true integrators. Having supported customers for a manufacturer, I can attest that there are many customers left unsure of who to trust. Tired and frustrated, they don’t want to trust any integrators. There needs to be a vast change in the way integrators handle customers. How we offer to help them, I believe, provides us… View this story

    For the majority of humans, there is nothing simpler than listening to sound. You simply, well, listen. When it becomes necessary to describe the listening experience analytically, however, a host of complex equations and diagrams are required to describe even the simplest of sonic events. The benefit of mathematical analysis is that it can yield insights that are not apparent through intuition alone. Acoustic signals are easily measured, and the audio components that produce them have characteristics that can be… View this story

    Sensaphonics has announced its expansion into the field of custom eye protection with the introduction of the 3D 20/20, the world’s first Active Ambient Optical Protection System. The system is designed to control the harmful rays from concert lighting systems, eliminating the strobing and glare that can cause headaches or even seizures among musicians and audience members alike. “The 3D-20/20 is, quite simply, a game-changing product,” explains Sensaphonics founder and president, Dr. Michael Santucci. “We’ve all been to concerts where… View this story

    In the great tradition of Heathkit®, Dynaco®, and Eico®, Lectrosonics is introducing user-assembled kits as a cost-saving alternative to its popular (and pre-assembled) SRb Series dual-channel receivers. The kits reduce the cost versus finished products by approximately 50 percent. Along with saving money, users can enjoy the exciting challenge of sorting, correctly identifying, placing and soldering all the tiny parts—over 1,100 in all! The SR Series Digital Hybrid Wireless® diversity receivers offer two independent channels and fit into the standard… View this story

    Cable selection presents two primary challenges: myriad choices and overall quality. I’ve explored these challenges and have defined six factors that can help point you in the right direction. These factors include appearance, durability, flexibility, sonics, conductivity and shielding. Let’s have a look. Appearance Understand the difference between the look of quality—like shiny gold-plated connector housings—and actual quality construction and materials. A primary problem arises when assumptions are made that the materials inside a cable housing are as fancy as… View this story

    Chapter 5 of PSW’s ongoing free white paper series in now available. (Get it here.) The new installment, entitled “Understanding Impedance In Audio Transformers,” brings clarity to the issue of impedance, and explains how transformers are of special interest because they are capable of transforming impedances, while also providing galvanic isolation and many additional benefits. The white paper series is presented by Lundahl, a world leader in the design and production of transformers, and is authored by Ken DeLoria, senior… View this story

    Many audio field technicians are now in possession of measurement systems that can be used to assist the listening process in equalizing sound reinforcement systems. But, they’re often surprised to find that the measured system response correlates poorly with subjective impression of how the system sounds. In other words, the system can sound good when it looks bad on the analyzer, and it can sound bad when it looks good on the analyzer. As a result, some users have become… View this story

    Opened in 1998, Benaroya Hall in Seattle hosts one of the last concert halls—the S. Mark Taper Foundation Auditorium—to be built in the U.S. that was entirely devoted to the acoustic delights of a full orchestra; as such it has in recent years fallen foul of the irresistible movement towards multipurpose concert venues. As Mark Turpin from acoustic consultants Jaffe Holden (Norwalk, CT) points out, “You can’t build concert halls like that anymore; it’s just not financially viable.” The nub… View this story
