How to connect the old-fashioned amplifier speaker to the computer and play the music on the computer?

How to connect an old-fashioned speaker to a computer:

1, need to prepare: speakers, computers, one-to-two computer audio cables;

2. Plug one end of the cable into the audio output interface of the computer and the other end into the audio input interface (left and right channels) of the speaker;

This connects the computer with the speaker. Turn on the computer and the speaker, and the sound signal of the computer will be output to the speaker, which can be used as the speaker of the computer.

Extended data:

ADAT format is included in the professional audio format. As a professional audio interface with TV station audio, the format of communication optical cable is often used. Use common single-mode and multimode optical fibers, and connectors that meet commercial communication specifications.

Connection of audio cable

Audio cable is more complicated than video cable, and there is a problem of balanced and unbalanced connection.

balanced connection

The so-called balanced connection is a connection mode that uses two signal lines to transmit a pair of balanced signals. Because the interference of the two signal lines is the same in magnitude and opposite in phase, the interference will be cancelled in the end.

Because of the low frequency range of audio, it is easy to be disturbed in the case of long-distance transmission. Therefore, as an anti-interference connection method, balanced connection is the most common in the audio connection of professional equipment. Dual-core shielded wires are also used as audio connection wires in household appliances, but they transmit left and right channels, which are two signals, and are not balanced connections.

Unbalanced connection

Unbalanced connection is a connection mode that only uses one signal line to transmit signals. Because this connection is easy to be disturbed, it is generally only used for household appliances or some occasions with low requirements. Take XLR connector as an example for specific connection:

1, balanced connection: 1 pin-connected shield, 2 pin-connected+terminal (also called hot terminal), and 3 pin-connected-terminal (also called cold terminal);

2. Unbalanced connection: 1 pin and 3 pin are connected to shield, and 2 pin is connected to+terminal (signal terminal).

What connection method to choose generally depends on the specific requirements of the equipment for the interface. If you can use the balanced connection method, try to use the balanced connection method. When connecting, be sure to read the instructions on the panel first, and it is best to read the relevant instructions and requirements in the instruction manual first.

In some cases, it may be encountered that the device interface at one end is a balanced interface and the device interface at the other end is an unbalanced interface. If the requirements are not strict, the balanced end should be connected by balance, and the unbalanced end should be connected by imbalance. Pay attention to the correspondence of each foot. In the case of strict requirements, it is necessary to use conversion circuits to change balance into imbalance or imbalance into balance.
