Knowing what the Class AB label means for the Yamaha A-S301 makes it easier to determine if it's right for your sound goals. Customer reviews can help out with this as well.

Musical Fidelity's A1 amplifier is a Class A design. Notice that the top panel is a huge heatsink (Image credit: What Hi-Fi?) A transistor needs a certain amount of bias current flowing through it to ...

The amp is rated at 50W per channel in high-biased Class A/AB mode, delivering most of its power in Class A state. All of which is a roundabout way of saying it has the power to drive a wide range ...

Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many classifications, and each class has ...

The six transistors in the output stage are placed halfway underneath the PCB and the main PCB is placed parallel to the heatsink, creating a solid module. 6 3 mm holes must be drilled to fit the ...

Class AB amplifiers have been the workhorses of the audio world, thanks to their simplicity, and their ability to deliver high power levels with low distortion. But there are also a number of gremlins ...

Diodes Incorporated (Nasdaq: DIOD) introduces the PAM8965 Class-D stereo audio power amplifier with an integrated synchronous boost converter. This hi ...

A class A amplifier gives you bragging rights and keeps your house warm, a class AB amplifier is what you’ll find in most Hi-Fi separates, and a class D amplifier will be lighter and cooler.

The Class AB amplifier circuit is the combination of both Class A and Class B amplifier. By adding the diode, transistors are biased in slightly conducting state even when no signal is present at base ...

The DC biasing circuit for T4 and T5 has one diode and two parallel-connected resistors. Preset VR3 is used to adjust the quiescent collector current of T4 and T5 and therefore the class of operation.

A Class AB amplifier is a highly used amplifier design for high-power RF applications, as well as other applications that require high power gain with minimal signal distortion. The main benefit is ...
