Welcome to Powered Speakers Central. Here you can watch videos from Randall (Vice President of OnlyFactoryDirect) and Tyler (Technical Support Manager of OnlyFactoryDirect) about the proper way to hook up mixers, iPods, iPhones, laptop computers and other components to powered speakers. We also have videos explaining the different features of all the Podium Pro Audio powered speakers. If you have a question that is not answered in the eBay listings or in these videos, please email Randall at Randall@onlyfactorydirect.com and we will make sure to either add that answer to the eBay listings or make a video with an answer to your question.

Here are the technical differences between Class AB and Class D amplifiers:

Class AB push–pull circuits are the most common design type found in audio power amplifiers. Class AB is widely considered a good compromise for audio amplifiers, since much of the time the music is quiet enough that the signal stays in the "class A" region, where it is amplified with good fidelity, and by definition if passing out of this region, is large enough that the distortion products typical of class B are relatively small.

In the Class D amplifier the input signal is converted to a sequence of higher voltage output pulses. The averaged-over-time power values of these pulses are directly proportional to the instantaneous amplitude of the input signal. The frequency of the output pulses is typically ten or more times the highest frequency in the input signal to be amplified.

Here is the short version:

Class AB amps are considered to be the “old school” amp. Almost all Class AB amps have cooling fins on the back to radiate out some of the heat caused by circuitry. Class D amps are a newer technology that allows the amp to produce the same amount of wattage as the class AB amp with less heat. Therefore class D amps do not have or need the cooling fins.
