What is AUX IN on a music center

Stereos and other audio players are equipped with various input and output connectors. One of them is AUX IN. This is an additional channel designed to reproduce a signal. And it has a fairly wide scope of application.

What is AUX IN on a music center

This channel allows you to transmit a signal from any external portable device to the center.

REFERENCE! Translated, this name means “additional”, “secondary”. Technically, it is designed in such a way that it is capable of receiving signals from mobile devices, for example, smartphones and players.

Older speaker systems have CD IN instead of AUX IN, but they are used for the same purposes.

What is AUX IN for and how to use it to connect

Through this channel you can turn on music on your phone or player, but play it through the speakers of the music center. This way, you can enjoy good sound on whatever device you have your music on. The center is often used to play a signal from a computer - AUX IN is also used for this.

AUX IN is located on the rear wall of the speaker system, less often on the front. Most often, this input is represented by 2 RCA (“tulip”) connectors, but “large” (6.3 mm) and “small” (3.5 mm) Jacks are also found.

The output channel on portable devices is usually min-Jack, which is considered standard for all headphones.So, to play a signal from a phone on a speaker system, you will need a suitable cable - most often mini-Jack - RCA. However, any wire will not work - you need a four-wire acoustic wire with an external copper braid.

ATTENTION! The necessary cable can be easily purchased at the store - they are still widely used, so they are sold everywhere. It’s also easy enough to solder it yourself from a headphone wire. You will need to replace the speakers with RCA plugs. Instead of the left earphone, you should make a white “tulip”, and instead of the right one, a red one.

Connecting the device is quite simple: the mini-Jack is inserted into a smartphone or player, and the “tulips” into the music center in accordance with the color. That is, the white RCA goes into the white input, and the red plug goes into the red one. Some models allow you to manually set the playback channel. In this case, you will need to select AUX mode.

Then all that remains is to turn on the music on your portable device. If there are no signals through other channels, the speaker system will reproduce it. There is also a combination of playback, for example, music can be played simultaneously via AUX and USB. In this situation, it is enough to select the desired mode or turn off the sound from other channels.

When connecting a smartphone, you have to leave it near the speaker system because of the wire. There is an interesting option for using AUX IN - this is a Bluetooth adapter. You can connect it to the center and play music from any other device. There will be no restriction on the length of the wire.

You can connect your TV or computer via AUX IN to use your stereo to play audio from those devices. This way you can achieve high-quality sound, for example, when watching movies.

AUX IN, despite its simple purpose, significantly expands your capabilities. Using various cables and adapters, you can connect almost any device to the system and enjoy good sound. With the correct placement of speakers, it is easy to turn the center into a kind of home theater.
