I've been trying to get ETF5 demo to work but I must be doing something wrong. First off, I have the SoundBlaster 16 PCI card in my computer. Something really weird is that when I do the setup test in "getting started" and use the LINE IN input, I get a strange result. The frequancy response is an erratic signal that rises lineraly from about 92 to 100 dB. I also tested the MIC IN input, and that will give me a response that is very similar to the one in the help file. But I can't use the MIC IN input because the RS Meter will not work with it (I guess because of an impedance mismatch). Anyway, ignoring the frequency response problem above, I have everything connected as follows (I do not have the BFD yet, I'm just trying to position the speakers in the room first): LINE OUT Left -> LINE IN Left LINE OUT Right -> Receiver's AUX -> Speaker being tested RS Output -> LINE IN Right. I can hear the MLS signal being output to my speakers perfectly, but I can't seem to get a good level reading from the RS Meter. It's always too low (between -20 and -30 dB). Any ideas... please...?
