2. Speaker wire - Wikipedia

   en.wikipedia.org/wiki/Speaker_wire

   Speaker wire is a passive electrical component described by its electrical impedance, Z. The impedance can be broken up into three properties which determine its performance: the real part of the impedance, or the resistance, and the imaginary component of the impedance: capacitance or inductance. The ideal speaker wire has no resistance ...

   en.wikipedia.org/wiki/RCA_connector

   The RCA connector [3] is a type of electrical connector commonly used to carry audio and video signals. The name RCA derives from the company Radio Corporation of America, which introduced the design in the 1930s. [4] The connector’s male plug and female jack are called RCA plug and RCA jack . It is also called RCA phono connector [5] or ...

4. Speaker terminal - Wikipedia

   en.wikipedia.org/wiki/Speaker_terminal

   Speaker terminal. A speaker terminal is a type of electrical connector often used for interconnecting speakers and audio power amplifiers . The terminals are used in pairs with each of the speaker cable 's two wires being connected to one terminal in the pair. Since speaker connections are polarized, the terminals are typically color-coded so ...

5. Speakon connector - Wikipedia

   en.wikipedia.org/wiki/Speakon_connector

   A Speakon connector is designed with a locking system that may be designed for soldered or screw-type connections. Line connectors (male) mate with (female) panel connectors and typically a cable will have identical connectors at both ends. If it is needed to join cables, a coupler can be used (which essentially consists of two panel connectors ...

6. Constant-voltage speaker system - Wikipedia

   en.wikipedia.org/wiki/Constant-voltage_speaker...

   Constant-voltage speaker systems are also commonly referred to as 25-, 70-, 70.7-, 100 or 210-volt speaker systems; distributed speaker systems; or high-impedance speaker systems. In Canada and the US, they are most commonly referred to as 70-volt speakers. In Europe, the 100 V system is the most widespread, with amplifier and speaker products ...

7. Audio and video interfaces and connectors - Wikipedia

   en.wikipedia.org/wiki/Audio_and_video_interfaces...

   Audio and video interfaces and connectors. Audio connectors and video connectors are electrical or optical connectors for carrying audio or video signals. Audio interfaces or video interfaces define physical parameters and interpretation of signals. For digital audio and digital video, this can be thought of as defining the physical layer, data ...
