Signal generator
The signal generator section can output to pink noise (pink noise generator) or sine wave tone (sinusoidal oscillator), and connect to the internal and external talk buses.
Signal generator controls on the control surface and GUI
Item Element Description
1 frequency/[freq] control knob Gives continuous adjustment of the sinusoidal oscillator frequency from 50 Hz to 5 kHz.
2 1 kHz/[1K] switch Overrides the swept frequency control (item 1) and provides a xed 1 kHz tone.
3 PINK switch Overrides the sinusoidal oscillator and converts output signal to pink noise.
4 OSC switch This OSC external switch connects signal generator output to talk external output XLR.
5 OSC switch
This OSC internal switch connects signal generator output to the control centre’s internal talk and talk
select buses. The internal talk bus can then be mixed onto any of the control centre’s buses by pressing
the internal talk switches associated with those buses, or mixed onto a group of buses by activating an
internal talk group (see “Talk osc/routing”).
6 level control knob Gives continuous adjustment of signal generator peak output signals from o (4) to +10 dB.
The OSC switches (internal and external) are the talk routing switches.
