    Feed The Brain. The primary job of a measurement rig is to acquire electrical and acoustical signals and feed them to the processor so that it can analyze, compare, slice, dice, fold, spindle and mutilate those signals and produce multi-colored charts, graphs and the all-important squiggly lines. “But my software can produce squiggly lines all by itself without all those bothersome wires, preamps and microphones. Isn’t that enough?” Maybe. It depends on whether you are getting paid to pose or… View this post

    AaroniaUSA, a division of Kaltman Creations LLC, is now offering compact, cost-effective and portable (battery-powered) signal generators. Specifically, the new BPSG4 RF signal generator provides up to 4.4 GHz, while the new BPSG6 supplies up to 6 GHz. Both run up to 4 hours in battery operation and can be programmed with intelligent batch profiles. In addition, both models work with a user-friendly software interface providing real-time remote control via an integrated USB connector. Signal profiles can be created and… View this post

    The reshaping of entertainment production wireless operations in the U.S. is currently underway, and it will impact all wireless microphone, in-ear monitoring and intercom system users – including those working in church sound – in the near future. The shrinking UHF band, where the vast majority of wireless systems currently operate, will get even smaller with the 2016 commencement of the 600 MHz incentive auction to allow the mass introduction of white space devices. Almost all of the remaining UHF… View this post

    When traveling to different time zones, we need to correct our time-keeping tools in order to align our activities to the local standard time. Very simple. Likewise in sound reinforcement systems, we often encounter multiple sources of misalignment, albeit in much smaller time increments. The importance of these misalignments is often subject to debate, but with the advent of a wide variety of very good digital processing products, correcting such anomalies is no longer out of reach for most of… View this post

    SynAudCon is presenting Making Wireless Work, an in-person training workshop, at the Tuscany Suites in Las Vegas on Thursday, December 3 and Friday, December 4. Making Wireless Work will focus on wireless microphone technologies, frequency coordination, band planning, RF fundamentals, FCC and spectrum allocation issues, and site survey commissioning procedures. Another topic to be covered is the effect that the upcoming 600 MHz incentive auctions will have on professional audio. Top wireless professionals, including noted RF consultant James Stoffo as… View this post

    “Subwoofers should be located on the floor if at all possible.” This is one of those classic bits of audio “conventional wisdom.” I hear it from system operators on nearly every project. But is it true? If we look at the physics of sound, we learn that, as with most things in the world of audio, “it depends.” So let’s start by discussing why the floor might indeed be a good place to put subwoofers. Placing any loudspeaker against a… View this post

    In the world of sound there’s an old adage that states, “Your system is only as good as the weakest component in the signal chain.” This is especially true of a system’s loudspeakers. They are the last link in the chain and are directly responsible for communicating everything that’s been done to the signal along the way. Going beyond simply delivering sound into a room, they actually become a living physical element, dynamically interacting with their surroundings. In other words,… View this post

    It’s 9 am and I’ve just tumbled off the bus into today’s venue, a.k.a., “The Naming Rights Arena,” another stop on the five-month, 59-city Rock This Country tour by Shania Twain that I’m working with VER Tour Sound. The first hour is spent helping the rest of the audio crew as we tip the first of two trailers (mostly PA). About an hour later, the second trailer is empty as well, and I’m able get to focus on my “real”… View this post

    The many benefits of in-ear monitors include improved monitor and front of house sound, better pitch perception and timing, consistent monitor sound from one venue to the next, elimination of feedback, reduced vocal fatigue, complete mobility with wireless systems, lower audience sound levels and… the potential to reduce the sound exposure of performers and protect their hearing. But there’s no guarantee of the widely touted hearing conservation for IEM users: “Your mileage may vary.” Monitor engineers are motivated to provide… View this post

      The reverberation time (RT) is one of the most fundamental room measurements. It gives a broad brush stroke description of the general acoustical behavior of a space, paving the way for the use of other metrics to determine clarity and direct-to-reverberant ratios. Wallace Clement Sabine was the first to formalize the RT into an acoustic metric. His method of measurement involved a program source, a stopwatch and a quiet room. Sabine determined that 60 dB of room decay was… View this post
