18 How to Interpret the Graphs As indicated in Things you can accompl ish with this application (page 3) , the reverb characteristics graph can be used as reference when determining the calibra tion time posi tion with the receiver’ s “Advanced EQ Setup” function. It is also a valuable means for c hecking the effect of measur es taken to impr[...]

19 How to Interpret the Graphs (Continued) Deciding the time period for Advanced EQ Setup calibration With conventional MCACC EQ calibration, the microphone input’ s data acquisition time was fixed at between 80 and 160 [ms] (red part of Figure 1).
