    Provided by HOW To Church Sound Workshops. &nbsp Every year, hundreds of musicians and audio techs suffer serious electrical shocks while on the job, and these incidents have the potential to be fatal. Therefore, it’s imperative to have a basic understanding of electricity to avoid possible electrocution, and further, this knowledge can help protect your equipment from going up in smoke. GFCI? No it’s not the name of an insurance company or a European sports car, GCFI is an abbreviation… View this story

    power amplifiers

      This article is partly technical, and partly philosophical. It’s about power, and has to do with how consumers use power ratings to buy products. It is not necessarily limited to audio, even though that is where it ends up. There are two primary uses for power ratings: 1) To describe the rate of work performed by (or energy consumed by) a product, and 2) Because of the previous item, to determine whether or not a product can perform a… View this story

      Why a “70-volt” system? A good question, and one that causes a lot of confusion among audio practitioners. Some common misconceptions about 70-volt (actually 70.7-volt) distribution systems: • There is 70.7 volts on the line at all times. • The 70.7 volts is a “carrier” that the audio is riding on. • A voltmeter across the line should measure 70.7 volts during the operation of the sound system. And there are many more. With that in mind, let’s take… View this story

      Could anything be more confusing than a “power rating?” The question “How many watts” can have many answers, depending on whether we are talking about amplifiers or loudspeakers. There are also many variables regarding how power is measured and specified. The numerous variables have rendered “face value” power ratings virtually useless. Why is “power” so hard to quantify? One reason is because it is time-dependent and constantly changing - much like the “value” of the stock market. We can… View this story

    audio power
    Pat Brown 04/29/15 06:03 AM,
      Trying to characterize amplifiers or loudspeakers only by power ratings is akin to trying to completely characterize a person by a photograph. There is always much more than meets the eye. Few subjects generate more confusion in the audio world than power. There is a very good reason for this—it’s a confusing subject, and one that can easily fool our intuition. Most of us are on a power trip—our attitude is that “more is better.” We want bigger amplifiers… View this story
