    radial engineering
    PSW Staff 04/07/14 06:57 AM,
    The new Radial Engineeringg SB-15 Tailbone, a high-performance signal buffer designed to sit at the beginning of the signal chain and drive multiple pedals without the added noise that can plague high-impedance circuits, is now shipping. The compact design begins with a standard hi-Z instrument input. The signal is then “tamed” using Radial’s proprietary Dragster load correction circuit to replicate the tone and feel as if connected directly to the amplifier. It’s then buffered via a 100-percent discrete, class-A unity… View this story

    Years ago, only car stereo makers would advertise “2,000 Watts Of Earth-Shaking Power!” But with the recent shift to switching power supply amplifier topology, we’re now seeing this with many pro-oriented products. What’s behind the hype? And what about properly matching power amplifiers and loudspeakers? Answers start by focusing on the fundamental unit of measure in audio, the watt. What is a watt? A strict definition according to Wikipedia: One watt is the rate at which work is done when… View this story

Well, when I connected the wire to one of the loudspeakers in the hallway, the entire system went dead! The plate on the back of the loudspeaker said something about 70.7 volts. What’s going on, and what the heck is… View this story

    phantom power
    Bruce Bartlett 03/01/14 01:20 PM,
    Unsure about phantom power? Let’s clear up the mystery. Nearly all mixing consoles and audio interfaces provide phantom power at their microphone input connectors. Most condenser mics need phantom power to operate, so you simply plug the mic into the mixer to power it. But the ways we use and connect phantom power can make a big difference in how well those mics work. So what, exactly is phantom power, and how do we apply it effectively? Understanding It Phantom… View this story

    Provided by Sweetwater.   Q: I’ve been getting quite a few questions from clients lately about UPS (uninterruptible power supply) systems.The problem is, most either want to run out to their local office supply store and buy what’s cheapest, which I’ve insisted probably isn’t the best idea, or they’re an audiophile who’s heard that on-line UPS systems are the way to go. What can I tell people who don’t understand the value of the (many) other types of UPS systems,… View this story

    Mike Sokol 02/05/14 03:12 PM,
    Provided by the No Shock Zone.   In part 1, we covered what voltage is and a bit on how it’s measured. Here let’s look at how to use a basic digital voltmeter to measure any power outlet or extension cord for proper voltage. The reason this procedure is so important is that sometimes venues do crazy things with power outlets. For instance. I was teaching a seminar last year in a “gymnatorium” and plugged in my little demo rack… View this story

    Provided by Sweetwater.   Q: I recently saw a Tech Tip here on ProSoundWeb about choosing the correct gauge of wire for loudspeakers, which really got me thinking. I’m just starting out in the A/V field and I really want to make sure I’m equipping myself with the best set of knowledge from the get-go. So my question may be simple (and a little open-ended); however, I could really use an explanation: What is impedance balancing? A: First of all,… View this story

    Provided by Sweetwater.   Q: I just got Pro Tools for Christmas and I’m working on setting up a home studio. I’m trying to make sure I have all the power and stuff hooked up correctly. Can I run both a UPS (uninterruptible power supply) and an AC power conditioner/surge suppressor, or should I only use one? A: The answer to this one is a bit surprising. If you’re using a UPS to power equipment in your studio, you may… View this story
