GLOSSARY-IX
Revision S2005-6 S-Type
sub-group Normally receives a signal via an on/off switch
only, with no independent level control.
sub-output Level controlled output of the resulting mixed
signals of the sub-group.
summed signal One or more signals that are electronically
added together.
switch-mode power supply A power supply whose operation is based on
high-frequency switching and may or may not
include an input transformer stage. The switch-
mode power supply output voltage variations
are filtered out by an LC filter.
test signal A signal that has a known voltage or power
level.
TIP Part of the 0.25” TRS carrying the in-phase-sig-
nal (hot).
TRS jack connectors A type of input or output connector where:
TIP = In-phase signal (hot)
RING = Out-of-phase signal (cold)
SLEEVE = Screen
VCA Abbreviation of Voltage Controlled Amplifier
VCA switch Allows the A & B outputs and matrix output on
an O/P module to be controlled by the VCA
fader directly below the module.
WRITE mode Indicates that a motorized fader is sending posi-
tion data to the CCM.
X-fade Also referred to as cross-fade, this feature of
CADAC’s console automation software allows
programmed cross-fading
XLR connectors A type of input or output connector where:
PIN 1= ground
PIN 2= + phase
PIN 3= - phase
zero-signal reference potential The potential of a point or area in a circuit, sys-
tem or sub-system that is conventionally taken
as 0 volts with respect to all other local voltages.
