12. s look like invesions from each other What I mean is as one waveform goes down the other goes up Like a mirror image center Perception is that the audio sounds like it is a little on the left If you look at the waveform it confirms this The right channel is about 2 3 the volume of the left right This almost sounds like they are equal but very very slightly more volume on the right The waveform confirms this There is about 10 more amplitude on the curve than on the left The solution it seems to sound best panned almost all the way to the right but not quite all the way like 90 I hate this because I was hoping to have a dumb way of just plugging it up maybe even using a mono cable and not have to tweak it on a mixer in order to get a good sound Anyone else have the same results My guess is that they are doing some funky processing to make it sound more stereo For one thing there are only 2 mics and one points directly forward and the other just to the side Confusing Also using a voltmeter there is about 3 x volts DC on both the left and right wires I d assume that I should be using a capacitor or something to filter off the DC Mike Spice Tue 05 Sep 2006 20 27 16 0700 Hey all thanks for the useful comments I am thinking about connecting 2 3 5mm mono stereo jack sockets to accomplish this however I am not sure which wires to connect to each jack Should I be connecting the white yellow 2black wires to th
