Type of audio wire

There are many varieties of audio wires, and the design concept is also very different, and the price is high or low.

When the ideal speaker cable and signal cable transmit signals between the audio equipment, the signal should not cause any loss, no distortion, and no external interference. However, in the music playback system, there are indeed a number of acoustic wires that play a role, and people's understanding of the role they play is not enough. In fact, choosing the right speaker cable and signal cable can make the complete sound system perform its best performance. When a sound device is equipped with a small sound cable, it will not let it in any way. Audio equipment can fully realize its potential when playing music. Therefore, the purchase of good audio wire can make the audio equipment have the best performance under the premise of spending as little as possible.

The following is a more comprehensive analysis of speaker and signal lines. The analysis will introduce the balance and unbalanced cables, the two-wire crossover cable, the matching of audio cables with audio equipment, and the purchase of audio cables . At the same time, it should be pointed out that some of the most expensive speaker cables and signal cables do not necessarily have the best sound.

First, some terminology related to speaker and signal lines will be introduced.

·Cable: Usually used in any kind of connecting cable (wire) in the sound system, but it is more than yesterday to refer to the speaker cable (called the speaker cable) between the power amplifier and the speaker.

• Speaker cable: The speaker cable is used to transmit the high-current music signal output from the power amplifier to the speaker.

• Signal line: A signal line is an audio signal used to transmit line levels in an audio system. The sound source (LP turntable, CD player, receiving tuner, and recording dock) is connected to the preamplifier and the preamplifier with the power amplifier to transmit analog music signals.

Unbalanced signal line: The unbalanced signal line has two wires and is mostly connected to an RCA plug, also called a single-ended signal line.

• Balanced signal line: The balanced signal line has three wires instead of two wires and is connected to the 3-pin XLR plug. The balanced signal line can only be used between audio equipment with balanced input and balanced output.

Digital signal line: A single signal line used to transmit a two-channel stereo digital audio signal from a CD turntable or other digital source to a digital processor. .

· Two-wire crossover cable: refers to the dedicated speaker cable used to connect a power amplifier through two sets of (pair) speaker cables instead of a set (pair) of speaker cables.

RCA plugs and sockets: RCA plugs and sockets are a common type of connection used to transmit unbalanced signals. Almost all audio equipment is equipped with an RCA socket to allow connection to unbalanced signal lines. The RCA socket is always mounted on the base of the audio equipment, while the RCA plug is the one used for the unbalanced signal line.

XLR plugs and sockets: The XLR plug is a three-pin plug for balanced signal lines. The XLR socket is mounted on the base of the audio equipment and is designed to be connected to the XLR plug.

• Terminal: Refers to the terminal for the speaker cable that is attached to the power amplifier and speakers.

• Five-way binding post: A terminal that can be inserted into a bare wire, forked lug or banana plug. This five-way binding post is mounted on the rear panel of most power amplifiers and speakers.

• Fork-shaped solder tab: Refers to a contact strip that is shaped like a fork for terminating the speaker cable. The fork-shaped soldering piece can be connected to the terminal of the power amplifier and the speaker, and is the most commonly used connecting piece for the speaker cable.

Banana plugs and sockets: Sometimes, some of the speaker cables are not terminated by a fork-shaped solder but a banana plug. A speaker cable with a banana plug can be plugged into the five-way binding post. On some European power amplifiers, there is a banana socket for connecting to the speaker cable.

• AWG Specification: Refers to the American Wire Specification, which measures the diameter of a wire (usually a speaker cable). The smaller the label of the AWG, the thicker the wire diameter. Usually, the wires used for lighting are 18th.

In addition, the simplest is to strip the bare wire ends of the outer insulation.

RCA plugs, XLR plugs, banana plugs and forked lugs, and bare wire ends are shown in the figure.
