First, both of them are wires. From the point of view of circuit (electronics), they can both build effective circuits. Let the audio signal transmit;

second, it definitely affects the sound quality and volume (the former is more obvious than the latter). These two products have different functions and different character indexes. The analysis is as follows:

1. Cable is for the purpose of (power) electric energy transmission. During the design and production, the technology, materials, structure and thermal processing. . . And so on are all around this purpose; The speaker cable is responsible for transmitting audio signals in the audio system. Similarly, its technology and materials. . . . Such as cable, distinct. It can be abbreviated as: the cable is heavy in power and light in waveform, and the speaker is heavy in waveform and light in power;

2. Therefore, the disadvantages of cable used in audio system are mainly: poor anti-interference (some are insulated, but basically not), unstable waveform (external disturbance and self-excitation), easy to generate clutter (material purity and process accuracy), difficult to meet the requirements of audio system (from the size of material process accessories, etc.), skin effect (distortion caused by inductance and capacitance, internal setting and external twisting).

to put it simply, cables used as speaker wires have two serious defects: one is that the transmission path can't guarantee the distortion index required by the sound system, and the other is that the reliability of the connector can't meet the distortion index. Therefore, replacing the speaker wire with cable wire has a positive and obvious impact on the sound quality, which is positively related to the sensitivity of the sound system and the listener's hearing. The volume reduction is not necessarily (clearly felt). Under the condition of good connection, the cable is originally used for power transmission, and there will be no obvious power attenuation at a distance of several meters.

the speaker cable is used to connect the power amplifier and the speaker, in which the current signal is much larger than the video cable and audio cable mentioned above. Because of the large signal amplitude, this kind of cable often has no shielding layer. For this kind of wire, the key is to reduce its resistance. Because the output impedance of modern power amplifier is very low, the requirements for the speaker cable are also increased, such as using large cross-sectional area or multi-strand stranded wire.

the function of the audio cable is to connect all parts of the audio and transmit audio and video signals. Many people think that the audio cable is just an accessory in the audio system, so there is no need to be so particular about it. Just find a few pieces casually. Of course, the sound can also produce sound and pictures, but in fact the effect has been discounted. Because, the transmission process of the audio signal from the disc drive to the amplifier and then to the speaker, or the transmission process of the video signal from the disc drive to the TV set and the projector has been affected by the poor transmission performance of the wire itself and external electromagnetic interference, which weakens and pollutes these influences, so that the audio can not emit high-fidelity sound, and the TV and projector can not reproduce lifelike. Therefore, it is necessary for friends who are using or will use the audio cable to know more about it, make a reasonable investment in it, and use it correctly, so as to ensure the best effect of the audio.

VideoTwistTM cable is a new brilliance &; Reg, this cable adopts unshielded twisted pair (UTPs), supports high-definition video transmission and accurate data transmission, and KVM (keyboard, monitor and mouse) technology. It is the best solution for professional video and data applications, and provides excellent low offset performance for component video applications, which conforms to and is suitable for TIA/EIA standards.
