    Sometimes the differences between a good and a great system design are the “little things” like cables, connectors, mounts, stands, rigging, and so on. So let’s shine a bit of light on these often overlooked aspects. Loudspeaker cables come in many styles and lengths but they all do the same thing, which is to provide two conductors to connect a passive loudspeaker to its respective amplifier output. The rule of thumb is simple: “Use the largest gauge cable possible and… View this story

    It may not seem so at first blush, but there are a few concepts as pervasive in live audio as the concept of impedance. It’s relevant to microphones, direct boxes (DIs), preamps, processors, amplifiers, loudspeakers, equalizers, crossover filters, and even the cables that connect them all together. In this article we’ll explore the principles of impedance, and examine how these concepts apply directly to our work in the field. Ohm Sweet Ohm In order to understand impedance, we need to… View this story

    This article is provided by ChurchTechArts.   This article, #InstallationFail, has been inspired by the many, many instances of bad installation practices I’ve seen throughout the years. I’ve been taking pictures and cataloging these for quite some time, and I figured it’s time to share them with the world. Now, I should point out I’m not publishing these to make anyone feel bad. Though some of you should feel bad for some of these installations. But that’s not the point.… View this story

    Energy Transformation Systems (ETS) introduces its new AES/EBU digital audio adapters. Model PA851 (Female XLR) and model PA850 (Male XLR) allow transmission of AES/EBU digital audio signals up to 100 meters over Cat5 UTP The exclusive ETS digital audio adapter (PA850 Series) is impedance-matched, balanced and isolated to provide AES/EBU signals over Cat5 or better unshielded twisted pair wiring. Testing has shown the signal performance over UTP is equal to that of 110 ohm single shielded twisted pair wire even… View this story

    What is impedance? Impedance is the AC (alternating current) version of the DC (direct current) term resistance, which is the opposition to electron current flow in a circuit and is expressed in ohms. Impedance (often abbreviated as “Z”) includes capactive reactance and inductive reactance in addition to simple DC resistance. Reactance depends upon the frequency of the signal flowing in the circuit. Capactive reactance increases as frequency decreases: inductive reactance increases as frequency increases. Because of this frequency dependence, impedance… View this story

    Switchcraft announce an addition to our HPC series of high current connectors for loudspeaker and power applications.  All HPC connectors are fully compatible with Neutrik Speakon connectors.  This updated 4 pole version (HPCC4FT) has the turn to lock latching mechanism that has become standard in these types of connectors. The existing version (HPCC4F) has an XLR-style push lock. In addition to loudspeaker applications,  HPC connectors are touch-proof, rated for 30Amps, and have been used for AC power applications.

    This article is provided by Gary   Operating the sound system from the mix position during a Sunday worship service, “it” all began when the first note from our grand piano was distorted. Hmm… We’d checked the piano channel and sound prior to the service, and all was fine. My first reaction to the distortion now being produced was to reduce the gain on that console channel, thinking perhaps the piano player was “nailing” the keys very hard. Yet… View this story

    This article is provided by ChurchTechArts.   I get to talk to a lot of churches now. Being involved with a number of church renovation projects each year, I hear some interesting strategies. One of those strategies is to not run conduit for AVL wiring, but to plan on doing what we call “free air” wiring instead. Free air is just what it sounds like; the cable is running through free air. There may be ceiling trusses or beams to… View this story

    A live concert or event often serves a wider audience than those seated in the arena. In addition to the audio in the house and video at the side of the stage, it might also be simulcast to a separate location, streamed on the web, recorded for archival or other purposes, and/or broadcast via radio or television.  To accomplish this task, audio signals from microphones and instruments must be split beyond the traditional front of house and monitor positions and… View this story

    Penn Elcom recently completed the design and installation of a wiring infrastructure for a new recording studio in Hasting for songwriter/producer Paul Godfrey, creator of the trio, Morcheeba. The installation, within an old Methodist Church building in the heart of the town, entailed delivering all the multicores, cables, stage boxes, patch bays, wall racks plus associated metalwork, and was overseen by Penn’s Leon Whipp who heads the company’s specialist wiring division. The building has been utilized meaningfully in the conversion… View this story
