18 How to Interpret the Graphs As indicated in Things you can accomplish with this applicati on (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). By cont rast, with the receiver’ s Advanced EQ Setup functio n allowing more professional equaliz[...]

20 How to Interpret the Graphs (Continued) Pattern 2: Different reverb charac teristics for different channels If the reverb characteristics differ for the different channels as shown in Figu re 3, equalization using the conventional Ac oustic Cal EQ acquired data between 80 and 160 [ms] (red part of Figure 3), so equalization was perfor med to gra[...]

33 Troubleshooting As you use the Advanced MCACC app lication, errors can occur for a variety of reasons, such as incompatibilities wit h other applications and the current configuration of your PC. If an error occurs, r efer to the troubl eshooting points below . If the tr ouble cannot be rectified even after checking t he points listed below , as[...]

34 Troubleshooting (Continued) Cause 1: An error message may appear if there are not enough system resources available. If an error message like the one shown below appe ars, re-start the PC, then star t the installer (PioneerAdvancedMCACC_e_ver_*_*.exe) with no other application s active. Cause 2: Installation of Advanced MCACC may fail becau se o[...]

35 Troubleshooting (Continued) T r y the followin g, in the order indicated. 1) In the setup screen of the receiver , check that “Star t the MC ACC application on y our PC” is di splayed. (This message indicates that the receiver is r eady to send data to the PC.) 2) Check that the RS-232C cable is properly connected. (Be sure to switch off all[...]

36 Troubleshooting (Continued) Cause: It is not possible to print reverb characteristics graph s displayed in the “ALL” mode. Print after selecting an individual channel or frequency graph . Cause: You may not properly use the applica tion software not corresponding to your receiver. Check the model number of your receiver and use the applicati[...]

37 Troubleshooting (Continued) Cause 1: The slope of the graph indicates the reverb characteristics. The reverb characteristics of the room itself cannot be corrected by equalization alone, so the angle of the graphs’ slope is the same before and after calibration. Through calibration, the graphs for the dif ferent frequencies move horizontally b[...]
