    Parallel and series connections: description and calculations

    In this article we'll explain impedance calculations as simply as possible, as well as describe the different types of connection.... Read more

    Loudspeaker impedance

    Measured in ohms (symbol, Ω, upper case Greek letter omega), electrical impedance is defined as the opposition to the flow of alternating current by means of presenting an electrical load. In a loudspeaker, impedance varies with frequency, so manufacturers often publish "impedance curves" showing impedance with frequency for passive units. These curves give us... Read more

    Balanced and unbalanced connections

    There are two basic ways to carry an electrical audio signal.


    • The first one is unbalanced. The signal is carried on a two-conductor cable. Unbalanced signal connectors have two pins, such as the RCA (also called Phono and Cinch, commonly used by home hi-fi equipment) and the unbalanced 1/4" (used in musical instruments and semi-professional audio). Multi-pin connectors can also carry
