A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

The Starke Sound Fiera4 is an exciting new four channel Class D amplifier. It provides plenty of power (130wpcx4) to juice your home theater in a light weight and energy efficient package. Read on.

Howdy guys - I have an XPA-2 amp hooked up to a pair of B&W683's and am curious how many watts (in real time) I am using. I am not worried about over driving the speakers or worried that the amp is ...

Some of the electrical signals we work with are said to be “floating” with respect to ground. A typical example might be a voltage drop over a shunt resistor in a power supply or a complex biomedical ...

The audio analyzer can measure electrical performance only at the output jacks available on the system under test. Therefore, no one can enforce the speaker performance because the speaker is enclosed ...

We often get asked how much AC wall power is needed to run a typical home theater system. There are lots of factors that determine this such as the number of AV components you have plugged into the ...

Most car audio amplifiers today are class A/B or D, due to a desire to keep power consumption to a minimum while still maintaining high power output and an acceptable (low) distortion level. Even when ...
