The load impedance of a microphone is the input impedance of the audio device that follows the microphone in the signal chain. Typically the device is a microphone preamplifier but could also be a filter,pad, or another audio device. We want the load impedance to be higher than the micropho...
What is a Linear Amplifier? What are Integrated Amplifiers? Discussion Comments ByMelonlity— On Jan 13, 2014 Here's something I didn't know about power amps -- one is almost necessary if you're running a record player (old school, I know) into a modern surround sound system. It seems...

A semiconductor is a substance that has specific electrical properties that enable it to serve as a foundation for computers and other electronic devices. It is typically a solid chemical element or compound that conducts electricity under certain conditions but not others. This makes it an ideal m...
Hello everyone, I am Rose. Today I want to introduce amplifier to you. An amplifier is a device that can amplify the voltage or power of an input sign...
What is a Pre-amplifier? A preamp, short for a pre-amplifier, is an electronic amplifier that prepares a small electrical audio signal for further amplification or processing. In essence, it’s the first step in the audio chain, taking a low-level input signal, often from a microphone or...
A headphone amplifier is a low power amplifier specifically designed for on-ear or in-ear listening devices. They come in all shapes and sizes, from integrated modules to standalone devices. Like standard hi-fi amplifiers, most are solid-state but some use analog valves. ...

Voltage amplifier In the circuit shown above, you can see an amplifier which is connected to a power supply of 20V, and having a voltage gain of 2. When a voltage of 5V is fed to the only input pin, the output will be 10V. The GND is considered as a common reference point for bot...
When there is a voltage present at the point of connection, utilize the continuity feature on your multimeter to check if the relay’s other side has a solid ground connection. Check its voltage at that location where its relay attaches to abatteryor another power source if the first two st...
