PSW Staff 04/05/11 05:09 PM, 0 CommentsTammany Hall recently opened on Manhattan’s Lower East Side and immediately asserted itself as a formidable player in the local music scene. Its owners have created a number of successful clubs in New York City and across the country, most notably Crash Mansion, also on the LES. Tammany Hall delivers a wide selection of excellent beers and mixed drinks across three floors: an upstairs balcony, a prohibition-style basement lounge, and a main room with a generous stage. The owners gutted… View this story

PSW Staff 04/04/11 05:06 PM, 0 CommentsAt the 2011 Prolight + Sound.Musikmesse 2011 in Frankfurt, Proel is introducing new HPX Series power amplifiers. The series includes models HPX 900, HPX1200, HPX2400, HPX2800, with output ranging from 900 watts to 2800 watts using power stages in Class AB and Class H and switching power supplies. All models are capable of providing their maximum rated power on a 2-ohm load. A selectable LPN (low-pass notch) filter allows for improved low-frequency response, providing more punch and greater dynamics while… View this story

PSW Staff 03/21/11 05:17 PM, 0 CommentsDanley Sound Labs, noted for producing high-quality professional loudspeakers and subwoofers, has just announced the introduction of power amplifier and digital signal processing products. The new Danley DSLA amplifier is available in four output power configurations, the DSLA 1.7k, 3.3k, 4.5k, and 6.5k. The model DSLA 6.5k delivers 6500-watts to a 4-ohm load in bridged mode or 2200-watts to two 4-ohm loads in dual-channel mode, and the other configurations follow a parallel name-to-output convention. DSLA amplifiers are capable of driving… View this story

Bob Lee 03/14/11 04:26 PM, 0 CommentsThis article, clearing up misunderstood electro-physics of power amplification technology, was first published in the March/April 2000 issue of Live Sound International magazine. Q.} What does a power amp do, anyway? A.) In a nutshell, a power amp takes your audio signal and provides both voltage gain and current gain to drive loudspeakers. The voltage gain is necessary because line-level audio runs around a volt, peaking at maybe 8 to 12V, and loudspeakers need more voltage than that to produce… View this story

PSW Staff 03/02/11 02:34 PM,Electric power companies have a good idea that has been applied to audio engineering. When they run power through miles of cable, they minimize resistive power loss by running the power as high voltage and low current. To do this, they use a step-up transformer at the power station and a step-down transformer at each customer’s location. This reduces power loss due to the I2R heating of the power cables. The same solution can be applied to audio communications in… View this story

Pat Brown 02/28/11 11:03 AM, 1 CommentHere’s a handy quiz for checking your knowledge about audio power. Rather than submit you to the typical “right or wrong” questions with exact numerical answers, I’ve elected to provide a different means of self-evaluation. I can tell you up front that the answer to every question is “It depends!” But what’s really being asked is “WHAT does it depend on?” At first glance it may seem that the question is not even related to audio. Don’t be fooled. Principles… View this story

Bruce Bartlett 02/15/11 12:48 PM,It’s an answer to a sound company’s prayers: low-weight, cool-running power amplifiers with low current draw. Look for switching power supplies in power amps, and switch-mode power amplifiers. Compared to a standard amplifier power supply, the benefits of a switch-mode (switching) supply are lower size and weight. Compared to a standard analog power amplifier, a switching amp tends to run cooler and draw less current because it is so efficient. In addition, the amp can be smaller and lighter because… View this story
