Oscillator
The word oscillator is a slight misnomer in this case, as the console actually
provides a comprehensive tone and pink noise generator!
The ‘Oscillator’ section (see right), located just above the DAW control TFT screen,
contains controls for frequency, level and routing of tone or pink noise to the Main
Mix and Track bus outputs and to the monitor outputs for use in monitor
calibration.
OSC ON – Activates the oscillator output (surprise, surprise!). It’s good practice to turn the oscillator off when
recording, to prevent any accidental routing to desk outputs.
PINK ON – Switches the output from tone to pink noise. Note that the pink noise level can only be adjusted
using the Pink ‘Cal’ preset.
The LEVEL control adjusts the level of the tone generator from -25dBu to +20dBu. When fully anticlockwise, a
preset ‘Cal’ level is selected that can be calibrated using the multiturn preset located below the level control; a
red LED lights to show when the level control is in the calibrated position. When OSC ON is selected, the
rotary FREQ switch provides six preset frequencies.
The oscillator may be routed to the Main MIX busses, the TRACK busses and the CHANNEL OUT(puts)
(individually or simultaneously).
The oscillator output is also available on an XLR on the centre section connector panel.
