I want to add this to the top as I think Brian brings up a good point in the comments section. The maximum SPL (or Maximum Input Sound Level) on the SP-PSM-8 is 113. Basically SPL levels are the loudest sound pressure level a microphone can take before the mic begins to introduce distortion. So, this could totally explain what was going on. If that is the case, 113 is pretty low (for what I do) and I need higher. The SP-PSM-3 can handle 120. Better, but is it good enough? The Rode Videomic can handle Maximum SPL 134dB SPL (@ 1kHz, 1% THD into 1KΩ load). So, it looks like I will need to send the mic I’m using back in and upgrade to this one. It’s a good thing I’m selling a different set of mics to cover this. ugh.
Back to the original post…
OK, I had time to look at and analyze the wave files from the Nana Grizol show the other night. I’ll post a couple of screen shots and a sample of what the mic recorded. If I have to use battery power with the new mic, then I have to work on how to set that all up on the camera (and look at spending more money). I’m writing this up as I’m going to email SP today and point them to these posts. That way they can tell me what I need and then I can make my decision to send the mic back or not. Either way, a decision has to be made in the next day or so as I would have to get the mic back quick.
From the previous post about the mic, you’ll know I was really excited about the new stereo mic for my camcorder. I was thinking that it had to be an upgrade over the ECM-909a and after reading this: “If you have been using the Sony MS907 or similar stereo mic, this mic will make you want to list your old mic on Ebay! It sounds better (much better bass and highs), can handle loud sounds better, is more sensitive for those quiet situations, and will take care of everything in-between, too.” I was sure it would be.
That doesn’t appear to be the case. You’ll have to download the sample as the mp3 I tried to embed sounded 100X worse than it actually does. So, I don’t know what the problem is. I would right click the file and choose save as. Here is the sample:

It sounds as if everything is overloading, but it isn’t. Here’s a screen cap of the whole song:

Notice that the levels definitely aren’t overloading and seem to be fine. So, why the issue. Here is another screen cap of just the wave file I uploaded:

Obviously the mic isn’t handling the loud sounds well, like I was lead to believe. So, maybe the batteries were dying? Well, the next night I took Torsten to see the same band when they played up in Anacortes. I bought two new six volt batteries and put them in. The new batteries produced the same results–distortion and overloading. I do notice that the levels don’t seem to be even meaning that one side of each channel appears to be recording higher (not sure how to describe that), but the levels are not too high. Here is a screen cap of that:

Is it the old brickwalling issues that was fairly common with Sony DAT’s and mic in? If so, would using a battery pack be useful? If so, what would be a compromise for that as it will be part of my mic set-up? Hmmm…
Or is there a better mic than the Sony 909a that doesn’t need to have phantom power and would be able to avoid the issues I’m running into? In fact, I’m thinking of sending the SP mic and buying the Rode Stereo Videomic, but will the same thing happen with that? I’m so confused.
