    This article is provided by Rane Corporation. Constant-voltage is the common name given to a general practice begun in the late 1920s and early 1930s (becoming a U.S. standard in 1949) governing the interface between power amplifiers and loudspeakers used in distributed sound systems. Installations employing ceiling-mounted loudspeakers, such as offices, restaurants and schools are examples of distributed sound systems. Other examples include installations requiring long cable runs, such as stadiums, factories and convention centers. The need to do it… View this story

    More Than One Way: Alternatives To High-Voltage Audio Power Distribution

    In audio terms, high voltage means that the output power of the amplifier is converted to a high-voltage/low-current signal for transmission over long distances and/or small wire gauges. The advantages of the method include low cost and rather “bulletproof” systems, and the downside is that the transformers required present yet another filter for the signal to pass through, often degrading the audio quality. Since loudspeaker lines should always be kept as short as possible, the ultimate realization of this involves… View this story

    This is the fourth segment in our series on design principles for distributed systems. For additional reading, be sure to check out the first, second, and third articles within the series. Subwoofers can make the difference between good and great business music systems. Light background or foreground music might not require subwoofers; however, even in systems where the bass doesn’t need to be a dominant factor, having clean, full low frequencies can make a big difference in the customers’ enjoyment… View this story

    Mel Lambert 06/10/11 10:42 AM,
    San Antonio is a city that prides itself on appreciating the local arts; the city’s museums are havens for visitors seeking to connect with the spirit of the Southwestern adventure. When the time came to develop an area that encompasses bridges across the San Antonio River as part of a 1.5-mile extension of the River Walk, the San Antonio River Foundation realized that sound would play a key role in capturing the essential essence of the region. Eight artists were… View this story

    A Detailed Guide To Constant-Voltage Audio Systems

    PSW Staff 03/02/11 02:34 PM,
    Electric power companies have a good idea that has been applied to audio engineering. When they run power through miles of cable, they minimize resistive power loss by running the power as high voltage and low current. To do this, they use a step-up transformer at the power station and a step-down transformer at each customer’s location. This reduces power loss due to the I2R heating of the power cables. The same solution can be applied to audio communications in… View this story
