PXWX70 Wonky Sound 

My Sony PXWX70s are not doing me any audio favors. I record loud, often screechy music from fiddles, banjo and hammer dulcimers played by my subjects (wired with Sennheiser ew100s). More often than not, the frequencies appear to "shock" my camera's audio to where it produces the "warbly/digital soup" you hear in these 4 samples (of music and voice). Is there a MENU adjustment I can make that will prevent this "shock" to the camera's audio in order to help maintain decent sound? Please reply either below (comments) or on the PXWX70 thread. Thanks!!
