the audio line-out connector of the device and the audio line-in connector of the

 

computer.

Audio line-out connector

Used to send audio signals from the computer to external devices, such as powered

 

stereo speakers (speakers with built-in amplifiers), headphones, multimedia

 

keyboards, or the audio line-in connector on a stereo system or other external

 

recording device.
