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.)
BUSS
An output destination in a mixer. For example, the left and right main outputs
are called busses, because you can send a channel to one or both of them.
Also spelled Bus
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.
EQUALIZATION
Electronic filters that adjust the level of certain frequencies. Used for tone
enhancement or to reduce extraneous sounds. Two types of EQ shapes are
Peak and Shelving, described below.
HI-Z (HIGH IMPEDANCE)
In the audio equipment realm, the term “Hi-Z” or “High-Impedance”
generally refers to inputs designed for passive guitar or bass signals (1MΩ
or thereabouts).
HPF (HIGH-PASS FILTER)
An electronic filter that passes signals with a frequency higher than a
specific cutoff frequency and attenuates signals with frequencies lower than
the cutoff frequency.
IMPEDANCE
Resistance in an electrical circuit measured in Ohms (Ω). Maintaining proper
impedance (between amplifier and speakers for example) is important to
prevent damage to the amp.
48V PHANTOM POWER
A voltage signal that runs through a microphone cable to power condenser
microphones. Harmless to microphones that don’t need it, except for very old
and/or damaged ribbon microphones.
SHELVING EQUALIZER CONTROL
Increase or decrease of all frequencies above or below a specific point.
(Compare to Peak Equalizer Control; see pages 8-9 for more information.)
TRS
Acronym for Tip-Ring-Sleeve — the three parts of a three-conductor (including
shield) audio plug. TRS phone plugs are often used for “balanced” mono
connections, or stereo “unbalanced” (head-phone) connections.
TS
Acronym for Tip-Sleeve, the two parts of an unbalanced, two-conductor
(including shield) phone plug. TS connectors are some-times called mono or
unbalanced plugs or jacks.
UNBALANCED
A two-conductor (including shield), high-impedance connection. These are
most commonly used for instrument connections and cable runs of less than
20 feet.
XLR
The three-pin connector universally used for balanced audio connections.
A balanced connection reduces outside noise and interference.
(See Balanced above.)
