A type of amplifier design where the output device is always on for both parts of a complete sinusoidal cycle. Class A is the most inefficient of all power amplifier designs, averaging only around 20%. Because of this, class A amplifiers are large, heavy and run very hot, due to the amplifier constantly operating at full power.

which better for vocal?

I know the basic differences between different designs and what they do but I could use a quick technological explanation from someone with the cold facts. What makes a piece of gear Class A, what requirements does it have to live up to ? And Class AB ? Class B ? Is solid-state simply a design without tubes ? Discrete is point-to-point-wired with no IC's or?

I was just wondering when a manufacturer says thier product is all class A circuitry, does this mean that it really does meet some strict standard or this is just a subjective thing.

Hey guys, just visiting a local studios website (a competitor of mine) and noticed he said his A&H Mix Wizard 16 is class A. (preamps) I have that board and like it a lot but is it class A? Just wondering. Also, anyone know of a good place to rent nice mic preamp amps? How bout finding a good used one other than ebay? Thanks guys.

What does something have to have or be to be classified Class A? Does it pretty much guarantee decent quality or is it more of a marketing thing?
