    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

    no shock zone

    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

    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

    Provided by Sweetwater.   Q: I have what may seem like a silly question, but I’ve been racking my brain and I can’t seem to come up with the answer. Well, not really a question, really, but I keep getting confused by this: “The continuous load on a fuse in an enclosure should not exceed what percent of its rating?” You see, I’m doing some work, and I noticed that the above question does not indicate enclosure size, which in… View this story

    LynTec has introduced the new Remote Power Control Mobile (RPCM), the first intelligent power distribution panel to bring three distinct new features to mobile power distribution, including motorized circuit breakers, current monitoring at the branch circuit level, and remote monitoring capabilities. Attendees of the upcoming LDI 2013 show in Las Vegas (Nov. 22-24) can get working demonstrations of the new RPCM at booth 1367. “We are thrilled to introduce our groundbreaking RPCM mobile power distro at LDI 2013,” states Mark… View this story
