Hi... sorry to butt into this thread, but I'm using almost the exact same equipment (MZ-N707) but with SP-BMC-3 bianural mics (not SP-BMC-2) and have been having some problems with distortion, both from the lower levels (bass on highly amplified concerts) and the higher levels (extremely loud or high vocals in a more intimate concert setting). I've gathered that I need either an attenuator or a battery box, and it seems like this contraption from Radio Shack supposedly does the trick as an attenuator: http://www.radioshack.com/sm-gold-plated-v...pi-2102975.html But is there a "real" attenuator out there I should get instead? I figured I would try this solution first since it is considerably cheaper than the battery box. A440, you've mentioned the battery box from Microphone Madness (MM-CMB-Mini) module several times... so this works with your MZ-N707 and the Sound Pro mics? I was looking at a battery box from Sound Professionals (that they recommended to go with the mics I have) and it also has optional add-ons of levels adjustment and bass roll-off. http://www.soundprofessionals.com/cgi-bin/...?item=SP-SPSB-1 However, with adding on both of those options, it brings this one to $99.00, whereas the one you recommend is only $50... Since bass has been one of my primary problems, this bass roll-off feature sounds very appealing. However, it seems I've gathered (from what I've read on these forums) that with the battery box and using line in, that might solve my bass problems anyway and I wouldn't NEED the bass roll-off. The levels adjustment is attractive to me, though, esp. because of the ridiculously annoying maunal level adjustment on the Sony models where you have to set the recording level manually, through those five million steps, EVERY time. This is difficult in "stealth" situations. I figured it would be easier to adjust levels if there's an easily accessible switch in this battery box. Anyway, just wondering if you have any recommendations on this... Thanks!!!
