1.2 Definition of Terms
Terms used in this manual:
Inputs: The physical inputs of the input unit; all input units have mono or stereo
inputs with A/B selection.
Analog inputs are equipped with 3-pin XLR connectors.
Digital inputs are equipped with AES/EBU inputs on XLR connectors, and
S/PDIF inputs on Cinch/RCA and optical (TOSlink) connectors.
Input Unit: An input unit is a hardware assembly installed within the console. All in-
put units contain two selectable mono or stereo inputs; all input signals to
the input units are connected to the input connectors at the rear of the con-
sole.
Microphone input units have transformer-balanced mono inputs on XLRs,
with selectable 48 V phantom supply and A/B selection.
Analog Line input units have two electronically balanced stereo inputs on
XLRs, with A/B selection.
On Digital Line input units, there is a selection of AES/EBU inputs on
XLR connectors, and S/PDIF inputs on Cinch/RCA and optical (TOSlink)
connectors available.
Each (A or B) input of every input unit is equipped with general-purpose
control inputs and outputs (GPIO) that can be used for fader start, mute,
signaling, etc.; these control inputs and outputs are available on D-type
connectors.
Input Channel: An input channel is the combination of all signal processing functions that
can be assigned to a fader strip, as A/B input selection, gain, filter, EQ,
pan/balance etc.; each input channel can be routed to any fader strip thanks
to the input channel routing performed in the DSP section of the console.
Fader Strip: A fader strip contains the operating elements for an input channel, as a
linear fader and a few keys and LEDs (e.g. ON, OFF, and PFL keys, and
OVL and AUTO TAKEOVER LEDs).
As the number of operating elements is reduced to a minimum, the adjust-
ment of some less often used input channel functions, as e.g. EQ setting, is
performed on the center touch-screen and the rotary encoders located next
to this screen.
