What is an Isolation Amplifier? An isolation amplifier (also called a unity-gain amplifier) is an op-amp circuit which provides isolation of one part of a circuit from another, so that power is not used, drawn, or wasted in a part of the circuit.. This will be explained thoroughly now, because this may, at first, appear to be a daunting topic, but, in this article, we will break it down into ...

Transformers are also used in DI boxes to convert high-impedance instrument signals (e.g., bass guitar) to low impedance signals to enable them to connect to a microphone input on the mixing console. A particularly critical component is the output transformer of a valve amplifier.

Transformers are most commonly used for increasing low AC voltages at high current a step-up transformer or decreasing high AC voltages at low current a step-down transformer in electric power applications, and for coupling the stages of signal-processing circuits. As a result, there is also no loss in terms of hysteresis and eddy currents.
