    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

    PSW Staff 08/03/16 12:24 PM,
    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

    impedance
    Jonah Altrove 08/02/16 01:32 PM,
    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

      With the wealth of knowledge about power available here on ProSoundWeb it’s a good idea to constantly evaluate our knowledge of power, or actually, your knowledge about power. Rather than submit you to the typical “right or wrong” questions with exact numerical answers, I’ve elected to provide a different means of self-evaluation. The test is “open book”, based upon the information shared in the article series and other resources, and I can tell you up front that the answer… View this post

    Provided by Live Sound Advice.   DI boxes (“Direct Instrument” or “Direct Inject” boxes) are very helpful tools in a live sound system. The most common type is called a passive DI, which includes an isolation transformer and ground lift switch.  The primary function of a DI box is to convert the unbalanced (1/4-inch 2-conductor) phone plug output on your keyboard or guitar into a low-impedance (low-z), balanced (3-conductor) XLR jack, which can be plugged directly into your signal snake… View this post
