What are 3 types of audio inputs?

Three common types of audio inputs are:

1. XLR Inputs: Typically used in professional audio equipment, XLR connectors provide a balanced connection, minimizing noise and interference.
2. 1/4-inch TRS Inputs: Commonly found on instruments and audio interfaces, these can carry balanced or unbalanced signals and are used for connecting Guitars, keyboards, and audio devices.
3. 3.5mm Aux Inputs: Frequently used in consumer electronics, this standard connector allows for easy connection of devices like smartphones and laptops to speakers or headphones.
