Dynamic parameters
Real audio parameters like e. g. fader or equalizer, the dynamics
unit or the pan/bal module.
Equalizer
An equalizer is used for adjust imbalances of the frequency
response of the amplitude (equalising non-linearities of the
frequency response).
Fader
Potentiometer often for gain adjustments
FC
Free Control
Control elements that can be individually assigned by the user.
Filter
Device or circuitry which changes the frequency response of the
amplitude (
Ј
Equalizer)
Floor
This value defines by which amount the input signal is diminished
when it falls below a certain threshold.
fps
Frames per second
The
Ј
SMPTE timecode subdivides the time in hours, minutes,
seconds, and frames.
Gain
The gain control serves for the adjustment of the level to the
requirements, i. e. an increase of the gain leads to an
amplification, whereas a reduction leads to an attenuation.
GPI/O
Actually GPI

General Purpose Interface
GUI
Graphical User Interface
Screen unit for performing a multitude of settings and
configurations.
Headroom
Modulation reserve, usually at +9dB (Germany)
High pass filter
Frequences above a defined limiting frequency can pass this filter
type, frequences below this value are attenuated with a certain
edge steepness.
High pass filter
Filter in the input of microphone amplifiers and gain faders to
suppress rumbling noises that occur when stepping noises
penetrate as impact sound the mic housing via the mic tripod.
Hold
Gate and expander allow to keep open the
Ј
VCA for a certain time
after the falling below the threshold. This parameter is named
hold; the respective time is the hold time.
HP
Horizontal pitches
Ј
5,08 mm resp. 0,2 inch
Input- channel
This channel type is used to edit supplied external sources
individually. The input channel receives its source signal via matrix.
The output signal is usually routed with the console-internal
summing buses to groups, sums or also tracks.
Insert point
Connection (combined input and output) that routes an amplified
signal into an effect device and back again into the signal path.
Insert return = Input of the insert point
Insert send = Output of the insert point
IT
Internationales Tonspurverfahren = international sound
Last access
Function to return to the channel accessed last.
Level control
Serves for displaying the input signal (input level) to be set by gain
control or fader that level peaks do not cause distortions but the
basic noise (signal to noise ratio) is drowned.
LFE
Low Frequency Effect = a channel for certain surround formats.
