AUS port is an auxiliary interface. Purpose of AUS interface: Its function is to output audio from electronic audio devices, and the port type is an asynchronous port. The AUX interface is mainly used for remote configuration, line backup, and can also be used for dial-up connections. It can also connect with a MODEM through a transceiver, supporting hardware flow control. The AUS interface establishes a command-line connection method between the user and the device, enabling operations that are usually not possible in user mode, such as initialization, restoring initial configurations, correcting abnormal user modes, etc. Common audio input interfaces: A common audio input interface is the RCA port. RCA is the English abbreviation for the lotus socket, which is not specifically designed for any particular interface.

AUX is a common audio interface in cars, more professionally known as an auxiliary input port. This thing is usually hidden in the center console or armrest, looking like a headphone jack. A few years back, this port was super handy—just use a 3.5mm audio cable with dual connectors to plug in your phone and play music in the car. But nowadays, new cars mostly rely on Bluetooth, so these ports are becoming rare, with Type-C or USB ports being more common in newer models. Actually, AUX is a favorite among old-school car audio modders—it’s super convenient for connecting external amplifiers to tweak sound quality. If you can’t find the port, check the manual; it’ll definitely mark the location. Using it is a breeze: just plug in the cable and switch the audio source.
