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 left), located above the TFT screen, contains
controls for frequency, level and routing of tone or pink noise to the Mix,
Record and Track bus outputs and to the monitor outputs for use in monitor
calibration (see page 4-22).
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 which can be calibrated using the multiturn presets 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 TRACK busses, the MIX bus and the RECord bus (individually or
simultaneously).
The oscillator output is also available on an XLR on the centre section connector panel.
