How to connect an MP3 module to a music center

Most people probably have an old stereo system lying around at home. But no one uses it for only one reason: it does not reproduce modern formats and does not support storage media. But the music center can be given a second life.

What is needed to connect an MP3 module

By design, the modules are a small mp3 player that does not have its own speakers and power supply. To fill these missing elements, an old stereo is used.

To remake a music center, it must be in working order:

• sound amplifier;
• columns;
• power unit.

For the alteration you will need:

• directly mp3 module;
• capacitor 470μF;
• printed circuit board;
• soldering iron;
• connectors;
• wires.

Important points before connecting

Today, manufacturers delight amateur craftsmen by producing a special mp3 module for sound conversion. This device can be equipped with:

1. Cheap products only have a USB port.
2. Expensive devices are equipped with a display.
3. Remote control that controls the equipment.
4. Different number of ports for different needs.
5. Certain devices may be equipped with audio amplifiers.

Recommendation! For home needs, a simple product with only a USB port is sufficient.

Step-by-step connection of an MP3 module to a music center

To install a modular part, you need to determine its location. If you are good with electronics, you can solder the modular board to the wires. If not, then you can connect this part to the cassette compartment. In this case, you need to take into account the possibility of controlling the remote control.

Main stages:

1. The audio system needs to be partially disassembled.
2. Taking into account the diagram of the modular board and the music center, it is necessary to connect the wires to the power supply to the corresponding output of the module.
3. Then you need to proceed to installing the modular board in the location that was selected. Why do you need to connect the corresponding terminals of the module and the sound card of the audio system. The procedure is performed with a soldering iron or using the aux input.
4. The last step of the upgrade is to connect the power supply and the job is complete.

Diagrams for the modular board and audio system are usually included with purchased models, otherwise they can be found on the Internet. The audio module must have a 5 Volt power supply. From 12 V it must be connected via a 12-5 V power supply.
