Pan and Operating Levels Preferences
The Pan & Operating Levels page is used to set the indication response of faders and Logicators and the overall
operating levels for the console.
The Pan & Operating Levels page will appear.
Fader Indication
By default, the alpha for the path on the surface will indicate the fader level when the fader is touched.
ä To prevent the alphas displaying the fader levels click the Fader Level Indication On Touch check box so the
X is removed.
The alphas will now display path names at all times.
Pan Logicator Arc
The sweep of the Logicators can be set to 180° or 270° for when they are used for panning. The lower value
allows the pan to be changed more rapidly with a greater panning effect for less Logicator movement.
System Operating Level
This sets the digital headroom to a value between 8dBu and 30dBu. The default is 18dBu.
Changing the operating level alters the PPM and VU meter sensitivity, offsets the level of the tone generator and
changes the dynamic processing threshold levels accordingly.
Operating Level Notes
0dBu = 18dBuFs. Levels are expressed in dBFS because the only useful reference point for digital signals is full
modulation of the digital signal path (similar to defining 0.775v rms as 0dBu)
Choosing Operating Level
The choice of operating level is primarily a question of the headroom preferred for a particular application.
However the need to interface with external equipment with operating levels that cannot be adjusted can also
determine operating levels.
Both operating levels and ADC/DAC scaling can be matched so that the console is consistent with external
devices in those circumstances. Having set the operating level the PPM and VU meters read zero (as marked on
the meter scale) when a signal at the operating level is present.
The console tone generator will produce a signal at the operating level when set to 0dB and dynamics
thresholds will be at the operating level when set to 0dB. This will be sufficient for all digital interfacing but the
utility only sets the operating level within the digital domain, therefore further adjustments may be required to
ADCs and DACs to set the desired operating level in the analogue domain.
