    This article is provided by Bartlett Audio.   As audio professionals, the more we understand what’s under the hood of modern power amplifiers, the better we can make a wise buying decision. What are the main sections or parts of a power amp? Every power amplifier includes a power supply, an input stage, and an output stage. Most amps also have protection mechanisms; some have DSP, and a few have networking capability. Let’s explain each feature… Power Supply Basically, a… View this story

    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 story

    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 story

    Rockin’1000, held a year ago with 1,000 musicians banding together in Cesana, Italy, to perform a cover of Foo Fighters’ “Learn to Fly,” returned again this yeat with 1,200 band members at Cesana’s Orogel Stadium for an open concert to a 14,000-strong crowd. The sound reinforcement system for the event was driven by LAB GRUPPEN PLM20K44 amplifiers. Weeks of planning were involved to bring together a team of technicians to realize the ambitious project for 250 drummers, 250 guitarists, 250… View this story

    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 story

    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 story

      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 story

    Festival season, in particular, means dealing with portable generators for show power. At performance venues, we hardly give power a second thought, simply handing our tails or feeder to the house electrician to tie into the “company switch.” Then we check the voltages at the distro end with a meter to make sure everything is connected properly, and that’s usually it – no more thinking about the power until it’s time to disconnect at the end of the gig.
