V 1.2
55/ 58
Effect which causes the signal to move automatically within the
stereo basis (left-right).
Panning table
Table which contains already defined points of the signal within the
stereo basis.
Panorama
Stereo basis
The stereo effect is generated when identical sounds are perceived
in the centre between two loudspeakers. The level ratio between
the two channels (position of the mono signal within the stereo
basis) defines the panorama position of a signal.
Peak- type- filter
also bell-type filter
The filter curve corresponds with a Gauß curve or bell.
Amplification or attenuation are performed around the filter
frequency. The bandwidth is defined by the Q factor. Bell type
filters are typically used for mid-range controls and parametric
equalizers.
PFL
Pre Fader Listening
The activated channels can be monitored with the headphones
without being influenced by the position of the channel fader. As
with the PFL function the channels remain unchanged, they are
used for controlling during the concert or a recording.
Phantom power
Power supply for condenser microphones. The mixing console
supplies the microphone with the necessary power of 48V via the
symmetrical audio cable.
Q- Faktor
The bandwidth of a bell filter which is calculated as dimensionless
ratio of middle frequency and bandwidth. The larger the ratio the
better is the quality and the smaller the controlled frequency band.
Ratio
Compression or expansion ratio in a dynamic processor.
Release- Time
Time the level needs to die away completely.
Reset
= Warmstart
Resets the system to the status after switching it on.
Return
Return line or auxiliary input of the effect signal, e. g. reverberator.
Routing
Signal routing
The routing of a way from input to output of a mixing console.
RU
Rack Units
Ј
44,45 mm resp. 1,75 inch
Sampling rate
Speed during collecting the measured values during the sampling
Send
Ј
Aux- Send
Send channel that serves for editing by external signals.
Sensing
Function: multiple use of an operating element by touching it
Shelving- Filter
Shelving filters are used usually for bass and treble controls.
The frequency response of this filter type is characterised by lower
edges and resembles with an increase to a steep and with a
decrease to a softly hanging cow’s tail.
Sigma
Signalmatrix
Tool for programming project specific special functions, i. e. freely
programmable buttons can be individually defined by sigma
programming.
Slope
Rise or fall within a curve with regard to an envelope.
SMPTE
Abbreviation for Society of Motion Picture and Television Engineers
Standardised protocol for the synchronisation of audio and video
