The sound can broadcast a good sound, and the wire is a key link in the sound system. Different levels of Hi-Fi speakers, amplifiers, and sources all have a certain level. Advanced audio even has its own unique technology and features in some aspects, and has a better balance between tone and volume. Most of the audio cables sold in the market are not listed with technical specifications. For the average enthusiast, the match between the wire and the equipment is at a loss.
The rendering performance of the sound transmission of the sound wire has the following four aspects;
In the first aspect, the signal transmission between the audio equipment is partially lost or unbalanced by the wire, which attenuates certain information in the sound spectrum. For example, the sense of the mid-range of the audio response range is reduced, the sound of the resonance box of the playing instrument is weakened, the sound of the chest of the human voice is weak, and the overall thickness of the sound intermediate frequency is reduced. In another case, the sound of the sound is high and low, that is, the lowest frequency and the highest frequency are weakened, and the intermediate frequency part performs well. The low-frequency sound is imaginary, lacking in density and detail and texture. The high-frequency part lacks detail and texture, and the width of the head and tail extends less.
The second aspect; the sound volume of a certain frequency band is more, the sound of this frequency band will be tight and hard, and it will be sharp and harsh if it occurs in the high frequency band. This kind of sound is hard to accept.
In the third aspect, the frequency response curve caused by the inductance and the capacitance in the acoustic wire is not linear and the phase drift is distorted. This is inevitable when making wire materials. It can only be applied by various manufacturers, using different weaving methods of wire, to minimize the existing inductance and potential cloth capacitance. The self-induction of the wire is correctly used in the acoustic wire, which is a very important topic in wire design. The pure resistance value of the wire has nothing to do with the frequency. The inductance and capacitance in the wire will have an effect on the sound, especially the extension of the high and low frequencies and the influence of the sound speed and transient.
The fourth aspect; the purity of the copper material used for the acoustic line, the crystal structure, the oxygen-free copper and the single crystal copper. The material of the oxygen-free copper has grain boundary distortion, and the copper purity is not high and there is impurity distortion. Most audio wire manufacturers use materials that typically have several N high purity copper. The grain boundary distortion is much less affected than other parts of the sound system, such as the connection between the boards inside the chassis and the wiring inside the speaker box. Most of the expensive wires are silver-plated ultra-high purity oxygen-free copper.
The structure of the audio wire is the key to the audio equipment to achieve high sound balance and low rendering sound design. The wire material is fundamental. Most of the materials used by the manufacturers are currently of good quality. Because there is no uniform standard for wire structure, each manufacturer's line has its own tricks, and the line technology is not open, mainly because of trade secrets. For different sound systems, it is rare to be able to achieve the absolute balance of sound through the wire. Most audiophiles are satisfied with the equipment and sound performance they are wearing, which is a very personal favorite. It is also the reason why audiophiles have different evaluations of the sound of the same set of audio equipment. Enthusiasts must practice a pair of golden ears. The first thing to understand is the structure of the sound.
The DMX console is the central controller for controlling all stage lights and special effects equipment. Almost all equipment needs to be connected to it, and users use it to issue control commands to all equipment. It can be controlled in real time, or the device can be programmed to display specific effects at a fixed time. Even with the stage equipment, the DMX console is also essential, just like there are more soldiers, the commander still needs to give orders to them. There are also many different types controllers to work for different quantity Stage Lights.
