8 MACHINE CONTROL
The OnAir 1000 provides different control inputs and outputs. These can
be used e.g. for switching an input channel on and off, or for starting,
stopping, and cueing of the connected source unit (as CD/cartridge/MD
players, tape recorders, or a CAB system). The control inputs and outputs
are input channel-related and are re-assigned together with the input chan-
nel signal to the respective fader strip if the channel routing is changed.
Each audio input holds two control outputs and one control input on D-
type connectors. The signals are:
• CTRL OUT 1 (normally used for fader start, but configurable for other
functions; see chapter 8.2.1 )
• CTRL OUT 2 (configurable functions see chapter 8.2.2 )
• CTRL IN (configurable functions see chapter 8.3.1 )
The status of the output signals depends on the control elements of the
fader strip (keys 1 to 3, fader, input selection, channel routing, and output
bus assignment), as well as on the console configuration.
Each input channel has two physical audio inputs, each of them with own
control input and two control outputs, allowing to control every external
source separately.
8.1 Keys and LEDs
Key 1/LED 1 The first key (labeled “PFL”) is always used to activate/deactivate the PFL
function; if active, LED 1 is illuminated.
The PFL function can affect the CTRL OUT1 and/or CTRL OUT2 control
signals, depending on the configuration. This configuration is performed in
the center part of the INPUT CONFIG. page and is identical for all types
of input units.
Key 2/LED 2 The second key (labeled “ON”) is used either to switch the input channel
ON or to toggle the input channel ON/OFF, depending on the configura-
tion of key 3. This function affects the CTRL OUT1 control signal. LED 2
always indicates the input channel's ON/OFF status.
