Hi all,
I have just taken the plunge and made my most significant investement in nature
recording yet. I have, after quite literally years of deliberation bought a
matched pair of DPA 4006's. I appreciate that two omnis are not the easiest
mics to get good recordings with, but with a little fieldcraft they are capable
of the most startlingly transparent but present sound.
I am however in need of your advice following up on the matched pair issue
raised with binaural mics recently.
I have seen DPA mics with ruler straight on-axis free field response but mine
have a 1/2dB variation with quite a few wiggles between 20Hz and 7kHz then a 1
1/3 dB rise starting at 7khz and peaking at 15khz, beyond 15khz there is a
1/2dB disparity between the mics.
My question is, what is more important having a pair of mics that are acurately
matched or having a ruler straight dB-frequency response (I have been given the
best matched pair of capsules they had) and are any of the stats quoted above
an "issue" in a practical sense given that DPA mics often have ruler straight
responses and subscribe to very high standards.
It has been a massive investement for me and although some of these things may
seem fussy I still have an opportunity to exchange them, so your advice would
be warmly welcomed.
Yours,
Tom
