    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… View this post

    Provided by the No Shock Zone.   Most musicians really don’t want to learn about electrical engineering, or even how basic electricity works. Everyone, however, should learn how to test for and avoid electric shocks on stage. Guitar amps and mixing boards as wired from the factory are inherently safe, but they can become silent-but-deadly killers if plugged into an extension cord or wall outlet that’s improperly grounded. This is because guitars are held in moist hands while wet lips… View this post

    Whether it’s a large festival line array rig or a single loudspeaker on a stick, all audio systems have one thing in common and that’s a need for power. Before starting to design, build, or use any power distribution equipment, the local laws and electric code should be consulted. The place to start is the National Electrical Code (NEC), sponsored by the National Fire Protection Association (NFPA) and published every three years. The purpose of the NEC is to safeguard… View this post

    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.

    First Baptist Church in Canyon Lake, TX recently celebrated the unveiling of a newly revamped sound system in its worship sanctuary, which is driven by new technology from Linea Research. As the church’s style of worship has evolved over the years, becoming more contemporary, it became clear that the existing vocal reinforcement system could no longer deliver the performance they now require. The church approached systems integrator Hairel Enterprises (Conroe, TX) to discuss options. “The existing sound system was more… View this post

    U.S. distributor TransAudio Group has released the new Drawmer CPA-50, a very small stereo (or bridged-mono) amplifier that can drive two 8-ohm loudspeakers at 25 watts (RMS) each, or double that wattage into 4 ohms. The CPA-50 offers thermal, overload and power up/power down protection and fault indication. In addition to working in stereo, it can also function as a 100-watt (RMS) into 8 ohms Monoblock (set via internal jumpers), which allows the system to operate in bi-amped or bridged… View this post

    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, as well as in part 2 to follow soon, we’ll explore the principles of impedance, and examine how these concepts apply directly to our work in the field. Ohm Sweet… View this post

    ATK Audiotek (Valencia, CA) deployed 104 Powersoft K10 power amplifiers to drive loudspeakers serving the recent Democratic National Convention at the Wells Fargo Center in Philadelphia. The systems served more than 180 speeches and 15 musical performances across the four-day duration of the event. ATK Audiotek, which also served the Republican National Convention in Cleveland the week prior, was charged with delivering reliable audio with high speech intelligibility for both events. This effort was led by ATK head system tech… View this post

    LynTec announces the addition of Telnet control to the company’s complete line of RPC series power control panels. Telnet expands RPC’s interface options, strengthening the lineup’s onboard monitoring and control capabilities from any remote location. “Installations are moving toward a shared Ethernet backbone, and we added Telnet to the TCP/IP protocol to meet the need for simple monitoring and control over the network,” says Mark Bishop, president of LynTec. “As a manufacturer, we have the most choices for control of… View this post
