    Kramer Electronics announces the acquisition of iRule, manufacturer of cloud-based control and automation software for commercial and residential markets. In 2014, Kramer announced a partnership with iRule to deliver control and automation technology – Kramer Control. This acquisition will enable Kramer to leverage the iRule software platform to best address a growing demand for advanced control and automation solutions.  The Kramer Control platform enables integrators to deliver control of lighting, HVAC, communications, A/V and more—along with worldwide connectivity, a critical… View this post

    This article is provided by BAMaudioschool.com.   Once upon a time I was doing the typical thing of going with what I was told worked or what I watched the engineers I had assisted do.  Specifically, I was recording piano with a pair of matching microphones in an XY pattern around the hammers. I knew about many approaches (another mic at the far end of the piano and then pan that mic over to the bass side of the stereo… View this post

    This article is provided by ChurchTechArts.   Editor’s note: This one obviously goes back a few years, but the information is worthy of repeating. One of my favorite scenes in Ghostbusters is when Egon gives the guys a warning about crossing the streams. As we know, it’s not good. Not good at all. Dr. Egon Spengler: There’s something very important I forgot to tell you. Dr. Peter Venkman: What? Dr. Egon Spengler: Don’t cross the streams. Dr. Peter Venkman: Why?… View this post

    This article is provided by Rane Corporation.   Objectively comparing pro audio signal processing products is often impossible. Missing on too many data sheets are the conditions used to obtain the published data. Audio specifications come with conditions. Tests are not performed in a vacuum with random parameters. They are conducted using rigorous procedures and the conditions must be stated along with the test results. To understand the conditions, you must first understand the tests. This article introduces the classic… View this post

    This article is provided by CCI Solutions.   A while back, I got the rare opportunity to work with the youth band at our church. These guys have an incredible heart and passion to worship and have loads of raw talent which translates into a powerful time of worship. When they lead, as a worshipper I feel free and emboldened to praise God the way He created me too. When they lead, as a sound operator I have to work… View this post

    Because of its fundamental importance in popular music, the electric guitar is the subject of intense scrutiny and wide differences of opinions. Just what makes a good guitar sound? Compared to all the subtle and not so subtle sounds that come out of an electric guitar amp, fidelity judgments of vocal sounds are easy to make! With good knowledge of the different guitar and amplifier sonic capabilities, coupled with good microphone techniques,we can achieve the ultimate guitar sound that “fits”… View this post

      It’s all about inputs and outputs (I/O). How do I get an audio signal from one to the other? The ongoing evolution of professional audio has produced a number of viable digital interfaces to complement legacy analog I/O practices. The choices may seem confusing at first, but when you break them down the strengths and weakness of each become apparent. In this overview, I will start with analog since it is familiar to most readers and serves as a… View this post

    In its most basic form, a DI – also known as a direct box and short for “direct injection” and/or “direct insert” – takes an unbalanced high-impedance signal (i.e., from an electric guitar or keyboard) and converts it to a balanced low-impedance signal. This process is needed when running high-impedance signal at long distances, such as down a snake to a front of house console. Unconverted, the unbalanced signal can pick up noise; also, sending high-impedance signal at longer distances… View this post

    Very often the topic of “room tuning” comes up in the practice of pro audio, but what we’re really talking about is “system optimization.” And over the course of many years, we’ve used many tools that seemed to—or actually did—contribute to desirable results. But system optimization is not just about turning knobs (virtual or otherwise) until things sound good. Sure, you can do that, and maybe that’s all you have time for under certain circumstances, but it’s not likely to… View this post

    Many believe that condenser microphones are more sensitive than dynamic microphones (moving coil) and therefore pick up “everything,” e.g., stage wash and noise. Sensitivity, however, is nothing but a constant conversion rate from pressure to voltage and more important, it is distance independent. Contrary to popular belief, it’s not the reason for picking up “everything.” Most condenser mics are indeed more sensitive. A Neumann KMS 105 condenser with a sensitivity spec of 4.5 millivolts at 1 Pascal (4.5 mV/Pa) is… View this post
