R-Type Revision R2005-2
D/O Direct Output.
DC Group A direct current bus that controls the VCA drive
voltage.
DC Master DC controlled fader serving as a master fader to
which one or more channel faders has been
assigned.
DC Master assignment Assignment of one or more channel faders to a
Master fader.
DC master membership Channel fader assigned to a certain DC Master
fader.
debug menu Menu with a number of options to assist in fault
finding and preventive maintenance.
dedicated stereo bus Bus exclusively used for stereo signals
destructive SOLO Pressing CHECK will invert the MUTE-function
so that all unmuted channels will become muted
and the muted channel will become unmuted. A
form of SOLO function.
Differential mode Currents flowing in a pair of signal lines that are
pricipally concerned with the signals them-
selves. Any induced interference on either line
appears to be in common mode with respect to
the signal currents (differential or normal mode)
and thus cancel.
DIM Feature on the Listen & Stereo output module
that attenuates the Listen L/S outputs 1 and 2
by approximately 20dB.
Direct Output Select The direct output signal is normally post fader.
Pressing the PRE button will take the signal
from pre-fader but post INS/EQ. Pressing MIC
will override the PRE button (the PRE LED will
go out) taking the d/o directly from the o/p of the
MIC amp. In this state the highpass filter is still
available if needed.
dual group Group module with odd end even mixing amplifi-
ers.
dual mono
A group module configured for dual mono oper-
ation.
Dynamic actions A dynamic action is defined as data contained
within a specific scene and lasting for a certain
length of time.
EARTH IMPEDANCE The total opposition to the flow of current in a
dedicated earth conductor. At frequencies
above 50/60 Hz, the total opposition to current
flow will be more inductive than resistive in the
context used (power supply mains connections),
Best results are achieved if the length of the AC
power input cables to the main and backup
PSUs are the same.
EDIT button Button on the CCM to be pressed when editing
the contents of a scene.
electro-magnetic interference Radiated and conducted phenomena associ-
ated with the electric and magnetic fields gener-
ated unintentionally by electronic circuits and
systems.
