I spent the day trying to correctly setup TMREQ on my AV32R yesterday and I must say it's far from being easy. In fact the case study is so outdated that it's discouraging. It doesn't take into account the changes in the AV menus and seems to be completely unaware of the TMREQ wizard 2.1. So please, could some TMREQ expert explain the latest choices available in the AV menus and tell how to setup TMREQ using BOTH ETF and TMREQ wizard ? So far, here is what I've done : 1) System calibration using the usual RS SPL meter (it seems inaccurate with low frequencies) and the AV speaker setup menu. 2) Connecting the laptop, the USB soundcard, the mic and preamp (those sold with ETF) and the AV together following ETF's help instructions 3) Checking the level settings as explained in the TMREQ case study 4) Measuring the subwoofer low frequency response and save it 5) but then ??? It looks like I can import the file in TMREQ wizard, launch the filters calculation and input the values in the AV without having to do any of the reconnections described in the case study, no ? These connections/reconnections seems to be completely useless to me, am I right ? 6) Once the filter of the subwoofer is in place, the case study explains that we have to re-run a speaker calibration and make a SPL level calibration in ETF... Ok it's official, I'm lost ! As I don't use the SPL meter with ETF but the mic + preamp, how can I have an SPL reading here ? Do I have to use my RS SPL meter "in conjunction" with the mic + preamp ? Last question : In TMREQ wizard and AV menus, there are several filter types. Could someone explain them. In which case, do we use them ? Does the wizard calculate filters other than peak ones ? Thanks in advance for your explanations.
