XLR cables have three pins and a circular connector. They are used to deliver balanced microphone and line-level signals over long distances. An XLR cable's ability to deliver a balanced signal means that the final audio signal will have less unwanted noise from outside electrical interference.What is an electret microphone?
An electret microphone is a type of electrostatic capacitor-based microphone, which eliminates the need for a polarizing power supply by using a permanently charged material.What is a condenser microphone?
Condenser microphones are essentially a highly specialized capacitor. For those of you without an EE degree, a capacitor is a passive electrical component that is designed to temporarily store energy in an electric field. Capacitors work by using two plates in close proximity with one another.
