GLOSSARY OF TERMS
BALANCED
A 3-conductor (including shield), low-impedance connection. Balanced cables are the preferred method for hum-free
interconnection of a sound system for their noise-rejection characteristics. (Also see Unbalanced.)
BUS
An output destination in a mixer, that allows for the routing of individual input signals. For example, the left and right main
outputs are each called buses, because you can send a channel to one or both of them by using the pan or balance knob on the
individual input channel.
CHANNEL
One of any number of signal paths in an audio circuit, such as input channel, output channel, recording channel, left channel, right
channel, etc.
DECIBEL (DB)
A term representing the ratio between different audio levels. It can either refer to the electrical signal running through a channel or
the acoustic sound level coming from a sound source.
DELAY
Like an echo, this effect duplicates the original signal, then plays it back at a rate you control. The rate at which these repeats
occur is the “delay time.”
