Put simply, its task is to turn high power DC from the power supply into high power AC for the speakers. Thus the amplifier is only one part of the circuit, and speakers, amplifier, and power ...

Most high-power amplifiers are designed to operate in the nonlinear region. A nonlinear vector network analyzer (NVNA) is the ideal tool to characterize and model such a device. By modifying the RF ...

As an amplifier’s output power capability increases, Class D’s efficiency advantages over Class AB becomes increasingly profound. Despite the historical image that switching amplifiers can never ...

An analog amplifier works in analogous fashion, regulating the output stage devices (transistors) to release power from the amplifier’s power supply to the loudspeakers in a manner that exactly mimics ...

– A new highly efficient power amplifier for electronics could help make possible next-generation cell phones, low-cost collision-avoidance radar for cars and lightweight microsatellites for ...

In addition, push/pull Class A designs are less susceptible to hum; single ended designs tend to require special attention to the power supply to mitigate this issue. A simple Class A diagram (left; ...

C ambridge Audio has added a power amplifier to its half-width MX range. It joins the five-star and multiple Award-winning ...

I'd be remiss if I didn't make note of the Z10's talents with headphones.The all-tube amp driving the speakers also drives headphones, only just reduced in power. The Z10 powers hungry high-end ...

The standard way to measure an amplifier’s output is by connecting it to an 8-ohm resistor and measuring the power before distortion becomes too high. However, the electronic load of a speaker is far ...
