No wonder, newly launched audio power amplifiers for example Mark Levinson No. 33H Monoblocks built a boom in the audio industry world. Product sizes are contracting at a faster scale turning everything into miniature. In the early days tube amps would give a commonplace and kept a larger part of the living room. These tube amps have been replaced by the solid-state amps for the most part. An amplifier or an amp is a device that can convert and enhance the amplitude of an input signal. This signal could be either a voltage or current. The power amplifier implies the amount of power which is to be transferred to the load. The points that one must to be taken care of while selecting amplifiers are certainly the power required and the acceptable frequency range.
There are some of the specifications of the power amplifiers which increase its importance at a great extent. The list of such specifications is:
· Transient Inter modulation Distortion: It is recognized as slew induced distortion, it happens whenever the input signal varies so quickly that output cannot keep pace with it.
· Input Sensitivity: It is the signal level which is needed to get full power at amplifier's output. It would be beneficial if all amplifiers ever had gained; despite the power applied to it. Sensitivity differs extensively and ranges from 500mV up to 1.5V or more.
In this manner, you can get a great output such as good quality audio from power amplifiers, i.e. Mark Levinson No. 33H Monoblocks.
