Level pop-up
The Level pop-up menu allows the user to program the indications shown on the blue "fuel gauge"
pop-up display which is indicated when the level pots are adjusted.
The microphone display scale menu allows adjustment of the scale of the level indication so that it will
correspond to the actual dBSPL value according to the specific sensitivity of the microphone being used. If the
sensitivity of the microphone is known (supplied by the manufacturer in the technical specifications of the
microphone), select the corresponding sensitivity for the microphone. The correct dBSPL indication will now be
shown as soon as a potentiometer is touched. If the microphone sensitivity is unknown, select "Attenuation"
so as to see dB rather than dBSPL. "Not indicated", can be selected so that the "fuel gauge" will no longer
appear when the potentiometer is touched.
In the Automatic position, the sensitivity selected in the inputs menu will be used as the scale for the fuel
gauge. This setting will have no effect on the input sensitivity only the scale of the level display.
If Attenuation is selected, then the indication will be in dB's from 0 when the pot is touched.
If a particular potentiometer is assigned to more than one input gain, then when the blue fuel gauge is
indicated it will only show the corresponding level in "dB" rather than "dB SPL" if their sensitivity settings are
different.
This selection will NOT alter the actual sensitivity of the pre-amplifier which is adjusted using the
Note:
potentiometer for the corresponding input.
For the line inputs and line outputs, the display can be selected to dBu or attenuation.
