Projectors with 3.5mm input

Input 3.5 mm (mini-Jack)

— usually, in this case, a linear analogue audio input using a mini-Jack connector is implied. This connector is more compact than RCA (see the relevant paragraph), in addition, it allows you to work with two stereo channels through one socket. On the other hand, a 3.5 mm connection is less reliable and more prone to interference. Therefore, such an input is designed mainly for simple tasks — such as transmitting sound from the audio output of a PC or laptop.
