Whether you are a seasoned pro audio expert or amateur home musician, at some point you will encounter phantom power. For many this occurs after purchasing a condenser microphone and wasting plenty of time trying to figure out why the thing isn’t working.
All condenser microphones (except electrets) require phantom power to operate. Phantom power is a DC current applied to the diaphragm of the mic. It is generated from pro audio equipment such as mixers and pre-amplifiers and supplied to the mic through a regular balanced microphone cable with 3pin XLR male and female connectors.

A TRS cable can carry either a balanced audio signal or a stereo audio signal. It depends on what audio output you connect the cable to. People often ask, “Are the TRS cables balanced?” The answer is “They can be, if you connect the cable between a balanced TRS output and balanced TRS input.”

Technically PA stands for Public Address, not Pro Audio as many people assume. The term public address literally means to ‘address’ the ‘public’. The public being a loud bunch of people, a system was obviously needed to amplify ones voice over that of the crowd. The PA was born.

Singers and vocalists will sometimes find themselves needing to plug their microphone into a guitar amplifier. Often for practice with other band members or in the home environment.
Though a guitar amp has its name for a reason; the input jack is designed for high impedance (Hi-Z) guitar signals, through a ¼” jack connector. While a microphone outputs a low impedance (Low-Z) mic level signal and the standard cable connector is a 3pin XLR.
There are ways to overcome the difference in signal and cable connectors to get the correct connection and optimum signal strength from the microphone.

Plugging a Laptop, MP3 or Ipod into a Balanced XLR Microphone Input
There are 3 things to note when plugging a "headphone level" signal from a laptop, Mp3 player or Ipod into a PA system via a balanced XLR microphone input.
This type of input is often found on mixers, pre-amplifier's and all in
one powered speakers. A balanced XLR microphone input will always be
accompanied by a pre-amplifier as mic signals are weak and always need
boosting before they are amplified.

Balanced audio, put simply, is a means to transfer an audio signal through a cable without picking up any electrical hum, often referred to as noise or noise-floor.
It is important to use balanced cables with microphones as they output such a low strength signal which makes the signal very susceptible to electrical hum. This is even more important when using long microphone cable lengths. Balanced cables are also a good idea when there are many cables running near each other, especially power cables.
