A nominal signal level which is around -10dBV for semi-pro equipment and +4dBu for professional equipment.

A device where the output is a direct multiple of the input with no unwanted distortions.

An automatic gain-control device used to restrict the dynamic range of an audio signal. A Limiter is a form of compressor optimised to control brief, high level transients with a ratio greater than 10:1.

see ADAT Lightpipe.

Low Frequency Oscillator, often found in synths or effects using modulation.

Liquid Crystal Display.

Light Emitting Diode. A form of solid state lamp.

The distance along the length of a cable over which the twisted core wires complete one complete turn. Shorter lay lengths provide better rejection of electromagnetic interference, but make the cable less flexible and more expensive.
