Revision S2005-6 S-Type
Out-of-phase signal A signal is said to be out-of-phase if the positive
and negative parts of the waveform are opposed
to the positive and the negative parts of a
source waveform to which it is being compared.
override Bypass or cancel a function.
pad Electronic circuit that attenuates an input signal
to allow for a line-level source to be connected
to a microphone input.
PAN Control Potentiometer used to place a signal some-
where in the stereo field.

P-Fade Programmable fader function.
PFL Abbreviation of Pre Fader Listen.
PFL to AFL Conversion of Pre Fader Listen to After Fader
Listen.
phase-change Change of the polarity of the in-coming signal.
PNG Abbreviation of Pink Noise Generator.
Pink noise Electronically generated noise that has equal
noise power per octave. This means that the
power per Hz drops at 3dB per octave.Thus the
power spectrum is similar to live music.
post fader metering The signal level displayed on the meter indicates
the level of the signal after the fader.
POST-FADE Indicates after fader.
post-fade signal The signal that is available after the fader.
Pre/Post fader monitor Function that allows the signal to be monitored
either before or after fader.
pre-fader signal A signal that is not controlled by the fader.
Pre-INS monitor A monitoring point before the insert stage.
PSU fault indicators LEDs on the CCM that illuminates when a power
supply system is connected to the console.
PSU SYSTEM One or more power supply systems that provide
power to the console.
Q-control The Q-control varies the bandwidth of the cut/
boost frequency selected on the equalizer,
thereby narrowing or widening the frequency
band affected by the EQ-section.
redundant configuration Cadac consoles are designed to allow the use
of two independent power supply systems in a
redundant configuration
– “main” and
“backup”. Both sets of power supply units are
used to power the console system so that under
normal conditions, the ‘load’ is shared between
the “main” and “backup” PSU’s. If a fault occurs
in one of the power units (causing it to ‘shut-
down’), the remaining power unit will continue to
power the console.
