【 Weak current College 】 signal lines on what sound---Power By 【 China power house network 】
Signal cable to the sound effects are what
In the audio sector, with the exception of the sophisticated amplifier, speakers, sound generators and other equipment, connect the signal wire is also quite high, the price of each line in the hundred-thousand or even millions of $, someone is not to say that in order to improve the sound quality will be money and effort invested in the wire is a great waste of, the improvement of the quality wire rod is very small, and its price compared to serious imbalances. Then the signal line whether the effect of the sound quality? I'm not an audio enthusiast, there are no fever frenzy on wire infatuation, but I also negative wire useless, I take a pragmatic attitude to discuss my views on audio wire. Any transmission cable is equivalent, on the grounds of resistance, capacitance and inductance of the distribution system, due to the presence of capacitance and inductance, so transmission cable has its special frequency characteristics of the signals of different frequencies are different delay (also known as different transmission rate) and render different impedance, obviously, this makes a certain amount of distortion signal generation. In addition, the cable resistance will signal generation loss, but because the audio signal connector are usually shorter, this loss can be ignored. But the speaker connectors cannot be ignored, because the power amplifier and speaker connectors are long and transmission of power, the connector's resistance on the amplifier output stage will have a direct impact (load impedance larger). Transmission line there is also a very important parameter is the characteristic impedance, although in audio circuits connect small-signal distribution, impedance matching is not high-frequency circuit or large signal circuit so fastidious, but if too much also affects the playback of the sound. Audio amplifier of audio sources generally have: radio, tape playback head, CD player, player, etc., these sources of output impedance is different, so when the matching characteristic impedance of wire should be sources equipment output impedance. We can use the signal cable is divided into strong signal line, the weak signal lines and standard signal lines are discussed separately: 1, strong signal line refers to the speaker and the connector between the amplifier, such lines are often not shield, for this kind of wire, the key is to reduce their resistance, because modern power amplifier output resistance is low, so at the request of the speaker cable is increasing, such as selection of the cross-sectional area of large or stranded wires. Wire from pure copper to the silver line are, more expensive price of a speaker cable for oxygen-free copper speaker-only lanes, it features good electrical conductivity, resistivity, use it in the playback sound timbre increased a lot. As a result of the transmission line to a different frequency signals have different impedance, this feature in the sound-reducing blur shown as the voice for the people produce a known as intelligent signal line of high-end loudspeaker connector, this line is characterized by a high or low depending on the signal frequency is divided into two channels, certain thickness of the outer lines of the above by 5KHZ signal, the signal through 5KHZ following line inside the transmission, which greatly improved the frequency characteristics of transmission lines, to replay sound clear and transparent. However if your amplifier output power of smaller or speaker line for shorter is not wasting money to use the expensive wire, in this case, the effect is not prominent. 2, weak signal line refers to the microphone to the connection between the preamplifier is usually shielded cable. 3. standard level signal line refers to the sound source and the connection between the amplifier, it's about the transport-level 1V is shielded type of transmission line. This line in the audio industry's most widely used, it is interesting, different dielectric and metal material wire sound quality is delicate, the manufacturers of a variety of types and specifications of wire rod and satisfy people's music appreciation level different requirements. High quality finished product line, with an antistatic layer of nylon braided sleeve for outer, lined with metal-mask set then use oxygen-free copper for the core wire, with gold-plated plugs, prevent plug contact bad and generate noise. Standard level signal wire brand: United States of MONSTER STANDRDINTERLINK (Monster), AUDIO0UEST (line St.), SUPRA (turtle fish), M0NITERPC (Magic), SPACE & TIME (time), M I S S I O N (Bel Canto), PATRDNICS (Po-force), and so on. Japan's MAKURAWA (Jimmy dew can be smelt), DENK0 (ascent), N I C S PATRD (Po-force), and so on.
Japan's MAKURAWA (Jimmy dew can be smelt), DENK0 (ascent), 0SONIC (Austrian Sonic), P C 0 C C (River) and ACROTEC (Japan mining), HISAGO (with crab), Guinness, voice, and so on, as well as European PHILIPS (Netherlands a Philips), V D H (Netherlands-million niedernhall), S X O I (United Kingdom-love cable wire), 0RT0F0N (Denmark-level wind), and so on, these cables are nothing more than through the use of different production materials and technology to achieve change improved frequency characteristics of sound playback, at best, only serve to improve the role of musical expression. If you are not a music fan or your power amplifier level is too low, you should never wasting money to buy those expensive audio wire, because if your amplifier on musical expression itself deficient, General wire and expensive wire effect is the same. According to one of my friends told me the audio, if your amplifier price no more than 2 million to use expensive wire does not improve the audio quality obviously. To sum up, a sound system, the standard level signal wire of sound quality of only secondary roles, expensive audio wire can only love expensive power amplifier. According to the size of the output power to choose the most appropriate speaker wire.
