Central processing unit in a digital signal processor on a board. The
DSP is used for processing of data in realtime, which means it can
permanently receive, process and give out data without
interruption. This allows also a permanent reverberation.
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
Filter Device or circuitry which changes the frequency response of the
amplitude (

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
⇒
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.

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 1) Frequences above a defined limiting frequency can pass this filter
type, requencies below this value are attenuated with a certain
edge steepness.
2) 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

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

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
