    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

    PSW Staff 02/26/14 09:20 AM,
    The new d&b audiotechnik D80 is a 4-channel amplifier offering sophisticated control capabilities and the power to efficiently drive d&b loudspeakers, along with comprehensive management and protection functionalities dedicated to mobile or installation applications. The high-power-density, 2 RU D80 incorporates digital signal processing to provide configurations for the entire d&b loudspeaker range. Each of the four channels integrated into the D80 feature a signal delay of up to 10 seconds and two 16-band equalizers, providing parametric, notch, shelving and asymmetric… 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

    PSW Staff 01/08/14 02:11 PM,
    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

    PSW Staff 12/23/13 01:18 PM,
    Juice Goose is now shipping the CQ 1 (“Qiwi”), a new concept in AC power sequencing that fits in a 2-gang wall enclosure and functions without a master control device, meeting a need for distributed, non-racked power control presented by the proliferation of powered loudspeakers. Qiwi operates just like the other Juice Goose CQ Series models with plug-and-play networking simplicity. It’s 15-amp duplex turns on with a single sequence event. Like other CQ models, the Qiwi has a sequence signal… View this story

    wireless systems
    Mike Wireless 12/19/13 07:05 PM,
    One of the topics that I’ve seen poorly understood, and even deliberately used to mislead people, is the issue of wireless microphone transmitter power and the effects said power has on system performance. Let’s start with the basics: all things being equal, more transmitter power = more range for the system, but not in a linear way. In broad terms, when discussing analog wireless systems, the receiver wants to see a signal from a transmitter (carrier) that is at least… View this story

    Crown Audio is now shipping the four highest-powered models in its DriveCore Install (DCi) Series of power amplifiers. Available in both DCi Analog and DCi Network Ethernet-linkable configurations, the 4-channel and 2-channel amplifiers deliver 1,250 watts per channel into 2, 4 or 8 ohms, as well as 70 volts rms and 100 volts rms (all channels driven; 2,500 watts in bridged mode). The models include the DCi Analog 4-channel DCi4|1250 and 2-channel DCi2|1250, and the DCi Network 4-channel DCi4|1250N and… View this story

    Ashly’s nX family of two- and four-channel power amplifiers has been expanded with the addition of twelve new 800 Watt and 400 Watt models. These medium output amplifiers are the perfect complement to the high-output 3,000W and 1,500W nX models. All nX Series amplifiers feature Ashly’s programmable outputs on each individual channel using rear panel DIP switches to select Low-Z (down to 2 Ohms), or High-Z, (70V or 100V) constant-voltage outputs. The nX8004 has four channels rated at 800 watts… View this story
