    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

    Do you really care if the power amplifier you’re using is a MOSFET (Metal Oxide Semiconductor Field Effect Transistors) or Bipolar design? Probably not, at least as long as the amplifier continues to perform. With modern amplifiers, few people notice the difference between the designs until the amp fails and they receive the repair bill. That’s when most people take a special notice. Keeping that in mind, let’s walk through some of the advantages, disadvantages and myths of these two… View this story
