2 – Basic operational concepts : Encoder mappingsTASCAM DM-4800 User’s Manual 25The Q encoders of each EQ band are used to controlthe Q (bandwidth), as shown here:Module levels and AUX sends The level isdisplayed up to the nominal level, and the nominallevel is marked by the lower indicator lighting withall indicators up to the nominal position half-lit.Levels above the nominal are shown by additionalsegments above the nominal segment lighting, andthose below the nominal position changing to half-litstatus, as shown in the illustration here.If the encoders are “flipped”, the position of thechannel faders is represented in the same way as foraux sends.Dynamics settings These are “rotary” settings,with higher levels lighting more segments. An excep-tion to this is the output level, which works in thesame ways as an EQ gain encoder.Other settings Aux levels from busses (includingthe stereo buss), delay time, and surround LFE levelsare also “rotary” settings, with higher levels lightingmore segments.Figure 2.17: Encoders in frequency Q adjustment modeHigh Q value(minimum band-width)A little wider Minimum Q(widest band)Figure 2.18: Encoders used to make module level and aux send adjustmentsFull cut Below nominal(0dB)Nominal (0dB) Above nominallevel
