    Church Sound: Understanding & Fixing System Ground Loops
    church sound
    Mike Sessler 02/20/13 10:11 AM,
    This article is provided by ChurchTechArts.   The topic for today’s post comes from a reader, Jonathan Mould. He wanted to know more about the electrical side of sound. This is an interesting topic because sound is both electrical and physical. Sound systems turn physical movement of air into electrical signals, then process and amplify those signals (sometimes changing them into streams of 1s and 0s and back), and finally turn those amplified signals back into physical air movement. It’s… View this post

    Portable Power: The Secret Life Of Generators
    live sound
    Craig Leerman 02/15/13 02:29 PM,
    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. The… View this post

    Crown Audio Retires D Series Power Amplifiers After 37 Years Of Distinguished Service
    image
    PSW Staff 02/12/13 05:58 PM,
    Crown Audio has announced that after 37 years of continuous production, the company is discontinuing its D Series power amplifiers. The Crown D Series became ubiquitous worldwide for its outstanding sound and reliability. It evolved from modest beginnings. “In 1977 we developed the D Series from the Crown SA20-20, a one-rack-space 20 watt per channel solid-state stereo power amp that was an accessory to the Crown tape recorders of the time,” says Gerald Stanley, director of research, Harman Professional Amplifier… View this post

    Behringer has introduced its most powerful iNUKE Series power amplifiers, the iNUKE12000 and iNUKE12000DSP, which deliver 12,000 total watts—6,000 watts per channel at 2 Ohms, or 3,000 watts at 4 Ohms. The new amplifiers weigh less than 18 pounds and occupy only 2RU. iNUKE amplifiers implement High-Density Class-D technology combined with efficient switch-mode power supplies. Front panel controls and indicators include positive-detent gain controls with signal LEDs that light when a signal is present, as well as clip LEDs to… View this post

  • In The Studio: What’s The Deal With Power Conditioners?
    recording
    Jon Tidey 02/07/13 04:24 PM,
    This article is provided by Audio Geek Zine.   A power conditioner is one of those items that might be pretty low on the “things to buy” list. But for a home studio, or especially a live recording set-up, definitely consider getting one sooner rather than later. So what is power conditioning? Power conditioning is a kind of vague term to that covers voltage regulation, surge protection, spike protection and noise reduction of the AC power that runs all your… View this post

    Understanding High And Low Impedance Signals
    prosoundweb
    Al Keltz 02/05/13 03:49 PM,
    The output from most electronic devices in an audio system will be of low impedance in nature, usually 150 Ohms or less. However, the output from many passive devices, such as a high impedance microphone or passive guitar pickup can have much greater output impedance. What’s the difference and why is it important to know how to deal with these signals in an audio system? Impedance (Z) is the measure of the total opposition to current flow in an alternating… View this post

  • Masque Sound Goes Back To School At Brooklyn Tech
    image
    PSW Staff 02/05/13 09:00 AM,
    When Brooklyn Tech High School, one of New York City’s most prestigious public high schools, needed to overhaul the outdated audio system in its 80-year-old auditorium, it called on Masque Sound to do the job. The company equipped the majestic hall with a range of state-of-the-art audio equipment. Built in 1933, Brooklyn Tech is home to the third largest auditorium in New York, second only to Radio City Music Hall and the Metropolitan Opera House. Featuring seating for 3,100 and… View this post

    Gary Gand 02/05/13 05:42 AM,
    For those who missed my first “newbie” column, here’s a re-cap. I’m the guy you love to hate, a musician almost from birth who is also a long-time professional sound engineer (35 years and counting). My goal is to inform and educate the less-experienced sound people that I work with on a regular basis from my spot at stage right in front of my guitar amp, behind my 36-pound pedal board, in my seven-piece blues, rock, soul – and whatever… View this post
