I asked in another thread about whether I could just use an XLR to 3.5mm converter to plug my recently acquired Senheisser ME66/K6 into my Panasonic NV-GS400 or whether I needed a Beachtek/Juicedlink pre-amp. As the K6 is battery powered the consensus was a converter would do.
However, I hit upon a gotcha that I hadn't considered. When I came to use it in earnest the signal is too loud for the camera. The external mic level on the camera can obviously be adjusted but the range (-30dB to +6dB) is not enough to prevent regular clipping (at 1m one person singing)
So, looks like I'll need a Beachtek/JuicedLink preamp after all to attenuate the signal further. Or buy a new cam with XLRs.
FWIW My Rode VideoMic does not peak (it has a DIP switch which allows one to attenuate the signal by 0, -10 or -20dB and on the advice of someone elase I had that set at -20dB anyway) also the ME66/K6 does not peak using a similar source when used in my Zoom H2 (with input level set to mid or low)
