L1202FX Owner's Manual
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.
REVERB
An audio effect that emulates the echo reflections and decay time
of a large space.
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.)
