How to connect speakers without a plug to a computer

When connecting old-style speaker systems, a problem arises in the form of the absence of a suitable connector on the speakers. Typically, a modern mini Jack 3.5 plug is used to connect to a PC. Older audio systems may not have such a plug. In this case, the user has to use an adapter. However, on some formats there may not be an adapter, and some adapters for some connectors are extremely difficult to find. In this case, you can make a cable for audio systems yourself.

How to make your own connection cable

To make the cable yourself, you should use shielded two-core wire. It will send a signal to the device.

• One end should be soldered to the wires or contacts that come from the audio system itself.
• The second end of the two-core cable must be soldered to the contacts of the mini Jack plug.

This port comes in two types: two-pin or three-pin. They differ in the signals that arrive at the input of the plugs.

• In a three-pin connector, two contacts are used for signal transmission for the left and right channels, and the third is for microphone operation.
• Older speaker systems do not have a microphone, so you will need a two-pin plug for proper operation.

The left and right channel cables should be soldered to the corresponding pins on the connector.After this, the soldering area should be insulated.

ATTENTION! All work should be carried out with the device turned off! Otherwise, a short circuit may occur, which will damage the speakers.

The procedure for connecting speakers with a homemade cable to a computer

After work on the plug is completed, you should connect it to the classic mini Jack 3.5 connector on the PC.

If, after connecting, strong noise and interference appear on the speakers, the insulation of the contacts may be damaged. As a result, the left and right channels are in contact with each other.

To fix this problem, you need to resolder the connector more carefully, remembering to insulate the working surface after all operations.
