  2. Balun - Wikipedia

    en.wikipedia.org/wiki/Balun

    In audio applications, baluns serve multiple purposes: they can convert between high-impedance unbalanced and low impedance balanced lines. Another application is decoupling of devices (avoidance of earth loops). A third application of baluns in audio systems is in the provision of balanced mains power to the equipment.

  3. Balanced line - Wikipedia

    en.wikipedia.org/wiki/Balanced_line

    In telecommunications and professional audio, a balanced line or balanced signal pair is an electrical circuit consisting of two conductors of the same type, both of which have equal impedances along their lengths, to ground, and to other circuits. [ 1] The primary advantage of the balanced line format is good rejection of common-mode noise and ...

  4. Balanced audio - Wikipedia

    en.wikipedia.org/wiki/Balanced_audio

    Balanced audio is a method of interconnecting audio equipment using balanced interfaces. This type of connection is very important in sound recording and production because it allows the use of long cables while reducing susceptibility to external noise caused by electromagnetic interference. The balanced interface guarantees that induced noise ...

  5. Antenna tuner - Wikipedia

    en.wikipedia.org/wiki/Antenna_tuner

    An antenna tuner, a matchbox, transmatch, antenna tuning unit ( ATU ), antenna coupler, or feedline coupler is a device connected between a radio transmitter or receiver and its antenna to improve power transfer between them by matching the impedance of the radio to the antenna's feedline. Antenna tuners are particularly important for use with ...

  6. Choke (electronics) - Wikipedia

    en.wikipedia.org/wiki/Choke_(electronics)

    Choke (electronics) In electronics, a choke is an inductor used to block higher-frequency alternating currents (AC) while passing direct current (DC) and lower-frequency ACs in a circuit. A choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a doughnut-shaped ferrite bead strung on a wire.

  7. AES3 - Wikipedia

    en.wikipedia.org/wiki/AES3

    AES3. AES3 is a standard for the exchange of digital audio signals between professional audio devices. An AES3 signal can carry two channels of pulse-code-modulated digital audio over several transmission media including balanced lines, unbalanced lines, and optical fiber. [ 1]

  8. Impedance matching - Wikipedia

    en.wikipedia.org/wiki/Impedance_matching

    Impedance matching. Source and load impedance circuit. In electrical engineering, impedance matching is the practice of designing or adjusting the input impedance or output impedance of an electrical device for a desired value. Often, the desired value is selected to maximize power transfer or minimize signal reflection.
