PSW Staff 09/12/11 09:58 AM, 0 CommentsThe new JBL Professional CSA-2120, debuting at PLASA 2011 in London, is a 2-channel power amplifier providing simple front-end amplification and a switch mode universal power supply. An auto-standby mode allows the amplifier to save energy by disabling the amplifier pulse width modulation generator when there is no input signal. The CSA-2120 also features thermal and low-voltage auto protection. The amplifier includes two optional accessories, a mounting kit and transformer module. The mount kit allows for installation into a cabinet… View this story

Bruce Bartlett 07/20/11 09:11 AM, 0 CommentsAs audio professionals, the more we understand what’s under the hood of modern power amplifiers, the better we can make a wise buying decision. What are the main sections or parts of a power amp? Every power amplifier includes a power supply, an input stage, and an output stage. Most amps also have protection mechanisms; some have DSP, and a few have networking capability. Let’s explain each feature… Power Supply Basically, a power amplifier uses the input signal to modulate… View this story

Mark Frink 06/21/11 07:44 AM, 0 CommentsMost modern power amplifier designs have abandoned traditional “linear” power transformer-based supplies in favor of digital switching supplies, shedding about half their weight in the process, getting into the range of 10 kilos or 22 pounds. Nearly all amps are two “rack spaces” high for a total of 3.5 inches in a standard 19-inch wide equipment rack, with depths ranging from roughly 10 to 20 inches. Various circuit designs have emerged over the years. Class AB designs provide low distortion… View this story

Live Sound Staff 06/02/11 09:06 AM, 0 CommentsUntil fairly recently, the audio power amplifier was almost as synonymous for excessive heat and weight as for its primary application. This reputation was the result of early inefficient output stages. Early designs dissipated most of the power drawn from the wall as heat, which then had to be sucked away from internal electronics with large metal heat sinks. Amplifiers have never enjoyed a reputation for being particularly sexy, being largely black boxes sporting a couple of big rotary dials… View this story
