PSW Staff 02/11/13 01:31 PM,With its parking lot in Kansas, its main entrance in Missouri, and its gaming facilities and guest accommodations in Oklahoma, Downstream Casino Resort is quite literally on top of the region’s historic tri-state junction. Recently Downstream Casino Resort undertook an ambitious expansion plan to add a six-story tower with 155 additional guest rooms, restaurants, event spaces, and spa services. The Tribe hired A1 Audio of nearby Branson, Missouri to design and install a comprehensive distributed audio system. A1 Audio delivered… View this story

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 story

Bill Whitlock 01/03/13 06:29 PM,After teaching seminars for more than 15 years now, it still amazes me how many otherwise competent professionals don’t understand the importance of proper equipment safety grounding. Even more shocking (pun intended), many routinely and casually disconnect safety grounds to solve noise problems! Generally speaking, the purpose of grounding is to electrically interconnect conductive objects, such as equipment, in order to minimize voltage differences between them. National Electric Code (NEC) requires that 120-volt AC power distribution in homes and other… View this story

Pat Brown 12/11/12 04:18 PM,By high voltage power distribution, we mean that the output power of the amplifier is converted to a high-voltage/low-current signal for transmission over long distances and/or small wire gauges. The advantages of the method include low cost and rather “bulletproof” systems. The downside of the method is that the transformers required present yet another filter for the signal to pass through, often degrading the audio quality. Since loudspeaker lines should always be kept as short as possible, the ultimate realization… View this story

PSW Staff 11/08/12 03:54 PM,Lowell Manufacturing Company has introduced the ACR-1508-S-HW, a new rack-mount panel that has eight 15A power outlets in the rear as well as a six-foot non-metallic flexible conduit for secure connection to the power source. The flexible conduit can be trimmed to the exact length needed and is much easier to route through tight spaces than a traditional metal-clad whip. The new hardwired panel measures 19 x 9 x 1.75 inches (w x d x h) and includes built-in surge… View this story

Chuck McGregor 10/31/12 12:22 PM,Clipping means that the tops of the signal are “clipped off” or “flat-topped” when the signal level is exceeding the maximum capability of the power amplifier or some other piece of equipment in the system. During the times when a signal is flat-topped, loudspeaker cones are not being “instructed” to move as it is receiving essentially a DC signal. This means all power goes into heating up their voice coils instead of producing sound. In other words, during the times… View this story

PSW Staff 10/23/12 09:22 AM,DigiTech has introduced the HardWire V-10 Power Block 10-Pedal Isolated Power Supply, a pedalboard power supply with 10 fully isolated outputs that deliver dependable, noise-free power for effects pedals. The HardWire V-10 Power Block’s isolated, high-current outputs and a shielded low-stray-field toroidal transformer eliminate hum and noise that can be caused by ground loops and interference. Four 9-volt outputs are provided, along with two pairs of 9V/12V merge-able outputs for power-hungry digital pedals, and two outputs with variable voltage from… View this story

Paul Mathews 10/22/12 03:26 PM,This article is provided by Rane Corporation. What could be more mundane than the transformers and autoformers that are the backbone of audio distribution systems? This article will show you that there is a lot more going on with these chunks of iron and copper than you ever suspected. Learn why transformers are often the power bottleneck in distribution systems, learn how to interpret datasheets, believe or disbelieve manufacturers’ claims, how to specify HV components, and how to set up… View this story

Pat Brown 10/16/12 05:26 PM,How much power can an audio amplifier produce? As you might expect, “it depends.” I will approach this from two angles - in theory and in practice. This article will deal with the theory. Part 3 will show how things play out in the real world. Importance Of Efficiency Amplifiers don’t make power. They convert it. Any audio power that comes from your amplifier must in turn come from the utility outlet that it is connected to. This is why… View this story
