The main task of the audio - is to transmit
a signal from the source to the receiver, in spite of all kinds of noise in
high quality. Thus, when transmitting an audio signal in addition there is also
the attenuation of inductance and capacitance problems that affect the quality
of sound timbre.
Therefore, the main parameter of the audio is
the percentage decrease in resistance. Manufacturers solve this problem by
making the cables of high conductivity copper. Mainly used oxygen-free, Electrolytic
copper, designated the cable and specifications as the OFC.
Conventionally, you can share all the audio
cables into two categories - Acoustic unbalanced cables and linear, i.e.
signal. The first option is namely linear cables for low level audio transmission
the value of tens of millivolts to a few volts and with a current of tens of
millivolts. Line cable connected to the
main different blocks, which include: a signal source, mixers and sound
processing equipment, power amplifiers. These cables come in two flavors -
balanced and unbalanced.
The second category, speaker cable (e.g. Mic extension cable), is used for transmitting single-ended line-level
audio signal, and it is all the signals used in consumer and computer
technology. At the professional level, unbalanced cables are used for
connecting musical power tools, other stereo sources. It’s often referred to as
a cable tool.
Acoustic unbalanced cable is made for both
stereo and mono. For professionals and advanced amateurs specially designed
expensive cables (e.g. 3.5mm 4 pole Audio jack) of excellent quality. They are made with the work
without external interference and the preservation of signal in its original
form. Cables high sound transmission, that is, there are high-quality and with
additional "bells and whistles". For example, the connectors may be gold-plated
wires made of 99.9% copper, although such refinements are not so important.
Though gilding and reduces the level of
resistance, but it is subject to more wear and tear than nickel, which means
that this option is not suitable for connector cables that connect regularly on
and off. And among the wires made of oxygen-free copper, the resistance is less
usual and depends on the width of the wire section.
