Wednesday, April 03, 2013Power Lines: Factors That Affect Power Transfer Between An Amplifier And Transducer
Pat Brown 04/03/13 11:36 AM,There are a number of possibilities for rating a power source. The most straightforward is a simple rating for continuous available power, a product of the maximum voltage (pressure) output times the maximum available current (flow) from the amplifier. This “Volt-Ampere” rating represents the largest number that could be used to characterize the amplifier. For the “ideal” amplifier, we could simply multiply the DC rail voltage times the maximum current available from the power supply into a purely resistive load.… View this post

Wednesday, February 20, 2013Change For The Better: The Emergence Of Multichannel Power Amplifiers
Jeff Kuells 02/20/13 06:33 PM,For years, power amplifiers with multiple channels (generally defined as more than two) were for either multiple headphones in studios or low-power-per-channel commercial applications. But are multichannel amps viable for mainstream professional sound reinforcement? You bet. Times have changed, and once again with regard to equipment, the change is for the better. Units with 3 to 6 channels have actually been around since the early 1980s. However, these either had a rather low power-per-channel rating or were fraught with design… View this post
