• Frequency response templates

    The illustrations below are templates for measuring frequency response. The first is useful for third octave band analysis, the second being useful for full resolution analysis. 25 and 50 dB ranges are provided on the left hand side (which corresponds to 1 or 2 dB per horizontal division). The illustrations have been re-scaled to fit on the screen; the originals (which can be seen by clicking on the image, though some browsers will resize it to fit the screen and show it somewhat blurry; if that is the case clicking on the image would normally in its original form) are high resolution. To download, just place your cursor on top of the image, right-click and select "Save image as".

    A example of a filled template for the 1/3rd octave template can also be seen. Only filled down to 31 Hz, where response falls approximately 15 dB below the average response level. Avoid driving the system too hard with bands outside the system's main bandwidth.

    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
