The exact value of any control will be shown on the Touch Screen using the Function Focus feature (see section 7.1) as you adjust them.7.5: DSP ELEMENTS > ACSUser Manual7.2.1: ACS INPUT SECTIONDSP ELEMENTS > ACS > INPUTThe input section mainly provides the features required for input channels such as phantom power and mic/line level. Metering is applicable to all DSP channel types, and HPF (High Pass Filter) is available in Mix Bus Master Channels.MeteringSignal level in channel shown as dBfsStereo channels use both L and R bargraphs, mono channels use the L/MONO bargraph. The scale is relative to digital 'full scale', so 0dBfs is the maximum before clipping. For input channels, the meter source is 'PRE' (just after the analogue-to-digital conversion but before the rest of the channel processing) so you can adjust for optimum Gain. The output/bus channel metering source is 'POST' (just before the physical output).48V Phantom PowerTurn 48V phantom power supply on or off.
