    There’s a lot to like when it comes to modern power amplifiers, and a variety of options abound. They provide tremendous power from far lighter packages, and in many cases, resemble a rack-mount processor more than a device capable of generating several thousand watts of audio power. The primary advancement in terms of power is efficiency. Greater output efficiency means less heat, and therefore, less weight, as well as more AC power making it to the loudspeakers. The most common… View this story

    power amplifiers
    Jeff Kuells 02/20/13 05:33 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 story

    In the classic sci-fi TV series Star Trek, Captain James T. Kirk of the Starship Enterprise frequently implored his chief engineer, Mr. Scott (a.k.a. “Scotty”), “We need more power!” And Scotty always did his best to comply with the captain’s request, regardless of the complications of the situation. Sound reinforcement system designers and engineers have made similar demands of power amplifier manufacturers, and like Mr. Scott, they’ve come through, and in spectacular fashion. The modern power amplifier is light years… View this story

    Brian Oppegaard 08/16/12 04:32 PM,
    Power amplifiers have been changing at a fairly rapid pace. Switching power supplies have reduced weight and offered added protection from line voltage variations. Class-D topology has cut the size of power supplies and heatsinks. Amplifiers are also shedding their conventional rack-mount chassis and taking up residence in loudspeaker cabinets. In light of these developments, it’s time to take a new look at the amplifier-loudspeaker relationship. We begin with the usual questions:  How many watts will that loudspeaker handle, and… View this story
